Bootstrap Select and dynamic rows issue in vue.js - vue.js

I have the following dynamic table/rows in vue.js and I use bootstrap-select to have a nicer dropdown select. The form has a add/remove line to be dynamic. I cannot load the options of a select using bootstrap select. The select appears on each row but no dropdown list appears.
What am I doing wrong?
here goes my jsfiddle
HTML:
<div id="app">
<table class="table">
<thead>
<tr>
<td><strong>Date</strong></td>
<td><strong>Account</strong></td>
<td><strong>Debit</strong></td>
<td><strong>Credit</strong></td>
<td></td>
</tr>
</thead>
<tbody>
<tr v-for="row in rows">
<td>
<input type="date" v-date="row.myDate">
</td>
<td>
<select class="selectpicker" ref="select" v-model="row.select">
<option value="Acc1">Account1</option>
<option value="Acc2">Account2</option>
<option value="Acc3">Account3</option>
<option value="Acc4" selected>Account4</option>
</select>
</td>
<td>
<input type="text" v-model="row.debit" v-on:keypress="isNumber(event)">
</td>
<td>
<input type="text" v-model="row.credit" v-on:keypress="isNumber(event)">
</td>
<td><a #click="removeRow(row)">Remove</a></td>
</tr>
</tbody>
<tfooter>
<td class="al-g"> <button class="button btn-primary" #click="addRow">Add Line</button></td>
<td></td>
<td class="al-r">tot D.: {{ totaldebit | roundme }}</td>
<td class="al-r">tot Cr.:{{ totalcredit | roundme}}</td>
<td class="al-r">Dif: {{ totaldebit-totalcredit | roundme}}</td>
</tfooter>
</table>
</div>
JS:
Vue.filter('roundme', function (value) {
return value.toFixed(3);
})
var app = new Vue({
el: "#app",
data: {
rows: [{debit:0, credit:0},
]
},
computed: {
totaldebit() {
return this.rows.reduce((total, row) => {
return total + Number(row.debit);
}, 0);
},
totalcredit() {
return this.rows.reduce((total, row) => {
return total + Number(row.credit);
}, 0);
}
},
methods: {
addRow: function() {
this.rows.push({myDate:"",
account:"",
debit: "",
credit: ""
});
},
removeRow: function(row) {
//console.log(row);
this.rows.$remove(row);
},
isNumber: function(evt) {
evt = (evt) ? evt : window.event;
var charCode = (evt.which) ? evt.which : evt.keyCode;
if ((charCode > 31 && (charCode < 48 || charCode > 57)) && charCode !== 46) {
evt.preventDefault();;
} else {
return true;
}
}
}
});

You are going to need a wrapper component like this.
The way bootstrap-select normally activates is to scan the HTML at startup and apply itself to .selectpicker elements. That won't work if the DOM is dynamic, as it is with Vue. You have to activate the elements using the $(element).selectpicker() method as they are created or updated.

Unable to set the value to the first input field using id of the field - in vue

I have an input field and a button (when clicked on displays a dropdown with few items) when selecting the items it has to be shown on the first input field. Similarly when clicking on the 2nd button where the dropdown is shown the selected value is shown in the 2nd input field. This entire runs in a for loop , which is where I am facing the problem.
<tr v-for="items in itemList">
<td valign="top"> {{items}} </td>
<td align="left" nowrap>
<input v-model="itemCode" type="text" :id="'item_code_'+items"
#input="handleInput"
size="20" maxlength="27"
autocomplete="off">
<br/>
</td>
<td align="left" nowrap>
<a id="myDropdown" class="dropdown" style="text-decoration:none;font-
size:10pt; padding-left: 10px;padding-right: 10px;"
#click="loadFavs()"
href="javascript:void(0)" title="Click to choose an item from your
favorites">
<img hspace="3" alt="Favorites" src="/images/icons/LoadFav.png"
height="16" width="16"
onmousemove="this.style.cursor='pointer'"
:id="'bd_fav_image_' + items" title="Click to choose an item from
your favorites">
<select class="dropdown-content" v-if="showFav" name="BOMList"
:id="'bd_list_'+items" style="font-size:10pt;width: 100%" v-
model="selected" #change="selectingFav(items)">
<option value=""></option>
<option v-for="(fav,index) in favList" :id="index" v-
bind:value="fav" :key="fav" v-bind:index="index">{{fav}}
{{index}}</option>
</select>
</a>
</td>
<td valign="top" nowrap >
<input type="Text"
:id="'bd_qty_ '+ index"
value="" size="2"
inputmode="numeric"
maxlength="">
</td>
</tr>
favList--> this list holds a list of items , For eg:- A,B,C,D
When I select A it has to be shown in the input field.
selectingFav: function(value) {
console.log("Inside the selectingFav..." + this.selected + "value is ." +value);
setTheValue(value);
}
function setTheValue(val){
console.log("Inside the setThevlaue");
if (val === 1 ){
console.log("inside the if");
$j('#item_code_1').val(this.selected);
console.log("inside the if witht the value " + $j('#item_code_1').val());
}
Tried setting the value based on the id of the input field but nothing is showing up.
If I set the v-model to the input field then all the 3 fields will be showing up the same value.
Can someone please let me know what is the issue. Hope these details are sufficient.
a) v-model is internally implemented as:
<input v-model="myval">
<!-- is --!>
<input :model-value="myval" #update:model-value="v => myval = v">
so you can freely define your own function
<input v-for="obj, ind of whatever" #update:model-value="v => myfn(v, obj, ind)">
b) same as you have an array you v-for on you may make a parallel array
// you get the idea
data: () => ({ imputs: entries.map(e => 0) })
<div v-for="entry, ind of imputs">
<Whatever :entry="entry"/>
<imput v-model="imputs[ind]">
</div>
c) keep your imputs in objects, generally the best choice
// you get the idea
data: () => ({ imputs: entries.map(e => ({ entry: e, input: 0 })) })
// or
computed: {pairs(){ return this.entries.map(e => ({ entry: e, input: 0 })) }}
<div v-for="item of imputs">
<Whatever :entry="item.entry"/>
<imput v-model="item.input">
</div>
Here is how you can achieve that.
data() {
return {
itemList: [
{ id: 1 , value: '' },
{ id: 2, value: '' },
{ id: 3, value: '' }
]
}
},
methods:{
selectingFav: function(value) {
// value holds the index
if (value === 1 )
this.itemList[0].value = this.selected;
else if(value === 2 )
this.itemList[1].value = this.selected;
else
this.itemList[2].value = this.selected;
}
}
}
In HTML template section
<tr v-for="(items,i) in itemList">
<td valign="top"> {{items.id}} </td>
<td align="left" nowrap>
<input v-model="items.value" type="text" :id="'item_code_'+items"
#input="handleInput" size="20" maxlength="27" autocomplete="off">
<br/>
</td>

display a foreign data in a table vuejs

I am creating a page, in which a section called product, I show data and in this I have a data called id_categoria, where instead of showing the id I want to show the name of that category in question, this data is in the table of categories and in the product table I have the id. I already managed to show the data, but not this, besides that I managed to save and edit it in question, it is only necessary in show.
When working with vuejs I saw that you have to use a v-if but I do not know how to do it, or at least the attempts I have made have been wrong.
this is the code of the table where I show the data
<div class="card-body table-responsive">
<table id="example1" class="table table-bordered table-striped">
<thead>
<tr>
<th>id_producto</th>
<th>imagen</th>
<th>código</th>
<th>producto</th>
<th>categoria</th>
<th>stock</th>
<th>precio_compra</th>
<th>precio_venta</th>
<th>fecha</th>
<th colspan="2" class="text-center">Acciones</th>
</tr>
</thead>
<tbody>
<tr v-for="pro in productos" :key="pro.id_productos">
<th>{{pro.id_productos}}</th>
<td>
<img :src="pro.imagen" class="img-circle elevation-2" alt="Product Image" width="60" />
</td>
<td>{{pro.codigo}}</td>
<td>{{pro.producto}}</td>
<td>{{pro.id_categoria}}</td>
<td>{{pro.stock}}</td>
<td>{{pro.precio_compra}}</td>
<td>{{pro.precio_venta}}</td>
<td>{{pro.fecha}}</td>
<td class="text-center">
<button #click="modificar=true; abrirModal(pro)" type="button" class="editar btn btn-primary"><i class="fa fa-pencil-alt"></i></button>
</td>
<td class="text-center">
<button #click="eliminar(pro.id_productos,pro.producto)" type="button" class="eliminar btn btn-danger" data-toggle="modal" data-target="#modalEliminar"><i class="fas fa-dumpster-fire"></i></button>
</td>
</tr>
</tbody>
<tfoot>
<tr>
<th>id_producto</th>
<th>imagen</th>
<th>código</th>
<th>producto</th>
<th>categoria</th>
<th>stock</th>
<th>precio_compra</th>
<th>precio_venta</th>
<th>fecha</th>
<th colspan="2" class="text-center">Acciones</th>
</tr>
</tfoot>
</table>
</div>
and this is the script to bring the info to me
<script>
import axios from "axios";
export default {
watch: {
$route: {
immediate: true,
handler(to, from) {
document.title = to.meta.title || 'Productos';
}
},
},
data() {
return{
productosdatos:{
id_producto: "",
codigo: "",
producto: "",
stock: "",
precio_compra: "",
precio_venta : "",
id_categoria: "",
},
id: 0,
modificar: true,
modal: 0,
tituloModal: '',
productos:[],
categorias:[],
}
},
methods: {
async listarcategorias(){
const res = await axios.get('http://localhost:8000/categoria/');
this.categorias = res.data;
console.log(this.categorias)
},
async listar(){
const res = await axios.get('http://localhost:8000/productos/');
this.productos = res.data;
console.log(this.productos)
},
cerrarModal(){
this.modal = 0;
}
},
created() {
this.listar();
}
}
</script>
as you can see I have a variable called products, where is the id_category corresponding to the product, and categories where I bring all the category info.
the table looks something like this:
how can I make it not show the id of the category but the name of the category in question ?
pd: the category data is received in json as follows:
{
"id_categoria": 8,
"categoria": "Electrodomesticos",
"fecha": "2021-10-24 13:55:00"
}
thank you if you can help me to show the name of the category thank you
You can implement a function like this:
const findCategory = (id)=>{this.categorias.find(category=>category.id_categoria===id)?.categoria}
And in the template:
<td>{{findCategory(pro.id_categoria)}}</td>
Only one small change. In your code you have to edit. pro.id_categoria to pro.categoria. see comment inline.
<tr v-for="pro in productos" :key="pro.id_productos">
<th>{{pro.id_productos}}</th>
<td>
<img :src="pro.imagen" class="img-circle elevation-2" alt="Product Image" width="60" />
</td>
<td>{{pro.codigo}}</td>
<td>{{pro.producto}}</td>
// this line
<td>{{pro.id_categoria}}</td>
// edit to
<td>{{ pro.categoria }} </td>

Vuejs2- Avoid repetition of select field options using vee-validate

Iam using vee-validate plugin for validation. In my form, there is a select field in the table. Rows will be added dynamically in the table. I don't want to select the same select(Description column) option again and again Image. Hence I want to throw an error like "Selected description already exists in a table" this using vee-validate. Kindly help me to solve this.

Thanks in advance.
You're on the right track, but a couple changes need to be made. When you call this.$validator.extend, that only needs to be done once - when your component is created. It attaches the check method to the validator, so then every time you have the attribute v-validate="'required|check'" in your HTML, it will run that check method.
In your check validator, you need to answer the question "is this value already selected". The answer is to go through the this.rows and see if any of them have the same billChgDesc property. Because this is in Vue, by the time the validator gets run, the row in question already does have that value, so you want to check if MORE than one row have that value. So, something like this:
mounted() {
var self = this;
this.$validator.extend('check', {
getMessage: field => '* Selected ' + field + ' already exists',
validate: function(value){
return (self.rows.filter(function(v){
return v.billChgDesc == value;
}).length <= 1);
}
});
}
This validator returns true if only one item has the given value. I'm using the built-in filter method of Array (see docs).
You can see an example of this all working here: https://jsfiddle.net/ryleyb/f9q50wx4/1/

vue.js does not correctly rerender compared to the vue instance object

I have a small issue with my vue template. The code is the following :
<template>
<div class="panel panel-default"
v-bind:id="'panel_'+noeud.id">
<div class="panel-heading">{{noeud.name}}</div>
<div class="panel-body">
<table class="table">
<thead>
<tr>
<th>Noeud</th>
<th>Poid</th>
</tr>
</thead>
<tbody>
<tr
v-for="noeud_poids in weightSorted"
v-if="noeud_poids.macro_zonning_noeud_id_2 != noeud.id"
is="macrozonningproximitenoeudpoids"
:noeud_poids="noeud_poids"
:noeud="noeud"
:noeuds="noeuds"
:delete_callback="delete_final"
:change_callback="update_line">
</tr>
<tr>
<td>
<select v-model="new_noeud">
<option value=""></option>
<option v-for="one_noeud in noeuds "
v-bind:value="one_noeud.id">{{one_noeud.name}}</option>
</select>
</td>
<td>
<input type="text" v-model="new_weight">
</td>
<td>
<input type="button" class="btn btn-primary" #click="addNoeudProximite" value="Ajouter"/>
</td>
</tr>
</tbody>
</table>
</div>
</div>
</template>
<script>
export default {
props: ['pnoeud', 'pnoeuds'],
data: function(){
return {
points: 0,
points_restants: 100,
new_weight:0,
new_noeud:0,
noeud:this.pnoeud,
noeuds:this.pnoeuds,
weightSorted:this.pnoeud.weightSorted
}
},
mounted() {
},
methods:{
delete_final(macro_zonning_noeud_id_2){
axios.delete("/macrozonning/proximite/",{
params:{
macro_zonning_noeud_id_2:macro_zonning_noeud_id_2,
macro_zonning_noeud_id_1:this.noeud.id
}
}).then((res) => {
Vue.delete(this.weightSorted, String(macro_zonning_noeud_id_2));
})
},
update_line(nb_points){
this.points_restants = this.points_restants - nb_points;
this.points = this.points + nb_points;
},
addNoeudProximite(){
axios.put('/macrozonning/proximite/', {
'macro_zonning_noeud_id_1': this.noeud.id,
'macro_zonning_noeud_id_2': this.new_noeud,
'weight': this.new_weight
}).then((res) => {
Vue.set(this.weightSorted, String(this.new_noeud), res.data);
});
}
}
}
</script>
When the function delete_final is executed on the last item of my list, the view is correctly rerendered as the last item of my list is removed. But when I try to remove the first item of my list then the view rerenders but the the last item has been removed. When I check the Vue object in devtools, it does not reflect the new view, but it reflects the action taken (my first item has been removed).
If you have any idea where this problem comes from it would be awesome.
Thanks a lot community
Use a key attribute on the element you are rendering with v-for so that vue can exactly identify VNodes when diffing the new list of nodes against the old list. See key attribute
<tr> v-for="noeud_poids in weightSorted" :key="noeud_poids.id" </tr>

Can datatables sort a column with an input field?

I am trying to make datatables sort my columns. The first column works okay as it's a simple number. However the next column is an input field. When I try to make that sort then nothing happens.
<table width="100%" cellspacing="0" class="table sortable no-margin">
<thead>
<tr>
<th scope="col" class="sorting" style="width: 57px;">
<span class="column-sort">
</span>
ID
</th>
<th scope="col" class="sorting_desc" style="width: 94px;">
<span class="column-sort">
</span>
Order
</th>
</tr>
</thead>
<tbody>
<tr id="row_20" class="odd">
<td id="refKey_20" style="text-align:center;" class="">
1Y
</td>
<td class=" sorting_1">
<input type="text" value="160" size="3" name="item.Order"
maxlength="3" id="Order_20" >
</td>
</tr>
<tr id="row_19" class="even">
<td id="refKey_19" style="text-align:center;" class="">
1X

<td class=" sorting_1">
<input type="text" value="150" size="3" name="item.Order"

Is there some way that I can get datatables to sort input fields?
The easiest way is to add a hidden span inside columns <span style="visibility:hidden">value of the input</span>
You should look at this example that explains how to do sorting on input fields. Basically you declare a sorting function
/* Create an array with the values of all the input boxes in a column */
$.fn.dataTableExt.afnSortData['dom-text'] = function ( oSettings, iColumn )
{
var aData = [];
$( 'td:eq('+iColumn+') input', oSettings.oApi._fnGetTrNodes(oSettings) ).each( function () {
aData.push( this.value );
} );
return aData;
}
And then tell to your table to use that
$('#example').dataTable( {
"aoColumns": [
null,
{ "sSortDataType": "dom-text" }
]
} );
or wit aoColumnDefs
$('#example').dataTable( {
"aoColumnDefs": [{ "sSortDataType": "dom-text" , aTarget: "yourclass"}]
} );
For versions of Datatables 1.10+ the names of some option variables have been changed and a new API introduced. Documentation here: http://datatables.net/examples/plug-ins/dom_sort.html.
Here is a working version of the above accepted answer in 1.10+:
$(document).ready(function () {
var table = $('#example').DataTable({
"columnDefs": [
{
"orderDataType": "dom-input",
"targets": 0, // Just the first column
},
],
});
});
The custom sort function:
$.fn.dataTable.ext.order['dom-input'] = function (settings, col) {
return this.api().column(col, { order: 'index' }).nodes().map(function (td, i) {
return $('input', td).val();
});
}
jQuery.fn.dataTableExt.oSort['textbox-asc'] = function (a, b) {
var vala = $('#' + $(a).filter('input').attr('id')).val().toLowerCase();
var valb = $('#' + $(b).filter('input').attr('id')).val().toLowerCase();
if (vala === '')
return 1;
if (valb === '')
return -1;
return vala < valb ? -1 : vala > valb ? 1 : 0;
};
jQuery.fn.dataTableExt.oSort['textbox-desc'] = function (a, b) {
var vala = $('#' + $(a).filter('input').attr('id')).val().toLowerCase();
var valb = $('#' + $(b).filter('input').attr('id')).val().toLowerCase();
if (vala === '')
return 1;
if (valb === '')
return -1;
return vala < valb ? 1 : vala > valb ? -1 : 0;
};
then use it like this
$(datatable).dataTable({
"iDisplayLength": 50,
"bLengthChange": false,
"bPaginate": false,
"columns": [
null, { "sType": "textbox" }
],
});
If you decide to use the columns option where you are rending information from a JSON file you can easily add a hidden span on your render property. It appears as though DataTables looks for text to order and if it cannot find any, it will break. The example at https://datatables.net/examples/plug-ins/dom_sort.html uses a table that has already been rendered. Here is an example using an API:
...columns([{
"data": "receivedDate",
"render": function (data, type, row, meta)
{
if (data == "null")
{
return "<input type='text' id='datepicker_" + meta.row + "' class='datepicker form-control' /><span class='hidden'><span>";
}
else
{
return "<input type='text' id='datepicker_" + meta.row + "' class='datepicker form-control' value='" + moment(data).format("MM/DD/YYYY") + "'/><span class='hidden'>" + moment(data).format('MM/ DD / YYYY') + "</span>";
}
}
}]);
Set an invisible div with the value before the input field.
<tbody>
<tr id="row_20" class="odd">
<td id="refKey_20" style="text-align:center;" class="">
1Y
</td>
<td class=" sorting_1">
<div style="display:none;">160</div>
<input type="text" value="160" size="3" name="item.Order"
maxlength="3" id="Order_20" >
</td>
</tr>
<tr id="row_19" class="even">
<td id="refKey_19" style="text-align:center;" class="">
1X
</td>
<td class=" sorting_1">
<div style="display:none;">150</div>
<input type="text" value="150" size="3" name="item.Order"
maxlength="3" id="Order_19" >
</td>
</tr>
</tbody>
