I am generating a some checkbox dynamically. Now I need to create v-model dynamic.
<div class="form-group input-group">
<label class="form-group-title">DIETARY PREFERENCES</label>
<p>Please mark appropriate boxes if it applies to you and/or your family</p>
<div class="check-group" v-for="v in alldietry" :key="v">
<input type="checkbox" v-model="userinfo.{{#Here will be the value}}" value="" id="Vegetarian">
<label for="Vegetarian">{{v.title}}</label>
</div>
</div>
into the v-model I have try v-model="userinfo.{{xyz}}" its shows error.
You can't use {{ }} interpolation inside attributes.
The v-model value is a javascript expression, so instead of
v-model="userinfo.{{xyz}}"
you can just do
v-model="userinfo[xyz]"
as you would normally do in javascript when accessing a dynamic property of an object.
To bind dynamic object to model, you need to access to key shared by the model value and the set of data used to display your list.
let vm = new Vue({
el: '#app',
data: {
userinfo: {
0: '',
1: ''
}
},
computed: {
alldietry() {
return [
{
id: 0,
title: 'Title'
},
{
id: 1,
title: 'Title'
}
]
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app" class="form-group input-group">
<label class="form-group-title">DIETARY PREFERENCES</label>
<p>Please mark appropriate boxes if it applies to you and/or your family</p>
<div class="check-group" v-for="(v, index) in alldietry" :key="index">
<input type="checkbox" v-model="userinfo[v.id]" value="" :id="v.id">
<label :for="v.id">{{v.title}}</label>
</div>
{{ userinfo }}
</div>

I have a dropdown list "functions" that is filled with database entries and a dropdown list with 2 hardcoded entries. When the vue website is opened the dropdown list remains empty but as soon as I change the value of the other dropdown field the desired data from the database is available.
I'm a bit confused because I expected that adding "retrieveFunctions()" into the mounted() function would trigger the v-for, and even more confused that changing something in another select field suddenly triggers it.
The HTML code:
<template>
<div class="submit-form">
<div v-if="!submitted">
<div class="row">
<div class="col-sm-12">
<p><a style="width:500px" class="btn btn-info" data-toggle="collapse" href="#generalInformation" role="button" aria-expanded="true" >
General Information</a></p>
<div class="collaps show" id="generalInformation">
<!-- NAME -->
<div class="form-group">
<input placeholder="Name" type="text" class="form-control"
id="name" required v-model="component.name" name="name">
</div>
<!-- DOMAIN -->
<div class="input-group mb-3">
<div class="input-group-prepend">
<label style="width:100px" class="input-group-text" for="inputGroupDomain">Domain</label>
</div>
<select v-model="component.domain"
class="custom-select"
id="inputGroupDomain"
>
<option value="Power System">Power System</option>
<option value="ICT">ICT</option>
</select>
</div>
<!-- FUNCTION -->
<div class="input-group mb-3">
<div class="input-group-prepend">
<label style="width:100px" class="input-group-text" for="inputGroupFunction">Functions</label>
</div>
<select v-model="_function" class="custom-select" id="inputGroupFunction">
<option :class="{ active: index == currentIndex }"
v-for="(_function, index) in functions"
:key="index"
value= _function.name>
{{ _function.name }}
</option>
</select>
</div>
</div>
<p>
<button #click="saveComponent" class="btn btn-success">Add Component</button>
</p>
</div>
</div>
</div>
<div v-else>
<h4>Component was added succesfully!</h4>
<button class="btn btn-success" #click="newComponent">Proceed</button>
</div>
The script part:
<script>
import FunctionDataService from "../services/FunctionDataService";
export default {
name: "add-component",
data() {
return {
component: {
id: null,
name: "",
type: "",
domain: "",
},
submitted: false
};
},
methods: {
retrieveFunctions() {
FunctionDataService.getAll()
.then(response => {
this.functions = response.data;
console.log(response.data);
})
.catch(e => {
console.log(e);
});
},
refreshList() {
this.retrieveFunctions();
},
},
mounted() {
this.retrieveFunctions();
}
};
</script>
refreshList() {
this.retrieveFunctions();
},
},
mounted() {
this.retrieveFunctions();
}
};
</script>
State in the beginning: Dropdown list empty
State after selecting something in the upper dropdown list: Database entries are visible and correct
You need to initiate all responsive properties on the data return object with either a value (empty string, array, object, etc) or null. Currently it's missing the _function attribute used in the select v-model and the functions array used in the v-for. You can try to change the data to the following:
data() {
return {
_function: "",
functions: [],
component: {
id: null,
name: "",
type: "",
domain: "",
},
submitted: false
};
},
I have form input using vue js and this input have button to add more column input this button. like this picture image. So on this single input I use v-model and its work , but on my new form this v-model and data binding didn't work. You can see my form like this :
on this new from , this v-model didn't work
<script type="x-template" id="form-input">
<div class="field">
<div class="field-body">
<div class="field">
<label class="label">Nama Barang: </label>
<p class="control is-expanded">
<input
type="text"
id="nama_barang"
class="input"
// v-model="userData.nama_barang" ---> if i add this v-model like this this form not showing , if i remove this its work , but i need v-model to store data
placeholder="nama barang">
</p>
</div>
<div class="field">
<label class="label">Satuan: </label>
<p class="control is-expanded">
<input
type="text"
id="satuan"
class="input"
// v-model="userData.satuan" ---> if i add this v-model like this this form not showing , if i remove this its work , but i need v-model to store data
placeholder="Satuan">
</p>
</div>
<div class="field">
<label class="label">Quantity:</label>
<p class="control is-expanded">
<input
type="number"
id="qtt"
class="input"
//v-model="userData.qtt" ---> if i add this v-model like this this form not showing , if i remove this its work , but i need v-model to store data
placeholder="Qtt" >
</p>
</div>
<div class="field">
<label class="label">Harga:</label>
<p class="control is-expanded">
<input class="input"
type="number"
id="harga"
//v-model="userData.harga" ---> if i add this v-model like this this form not showing , if i remove this its work , but i need v-model to store data
placeholder="Harga">
</p>
</div>
<div class="field">
<label class="label">Harga Total:</label>
<p class="control is-expanded">
{{(userData.qtt * userData.harga) | currency}} // its didnt work because this v-model didnt work
</p>
</div>
</div>
</div>
and its my export default
export default {
data(){
return{
fields: [],
count: 0,
userData:[{
rek_id:'',
tgl_pengajuan:'',
suplier_id:'',
status:'Aktif',
}],
rek:{},
suplier:{},
fields: [],
count: 0,
}
},
components:{
},
methods:{
submit() {
this.errors = {};
axios.post('/pengadaan/store_induk_pencairan', this.userData).then(response => {
window.location = response.data.redirect;
}).catch(error => {
if (error.response.status === 422) {
this.errors = error.response.data.errors || {};
}
});
},
addFormElement: function(type) {
this.fields.push({
'type': type,
id: this.count++
});
},
},
so how this v-model on new form can work like one single form ? this v-model only work on only first form
userData is a array, but in the v-model, you are calling like a js object
I have a button that should toggle and also call a method. How do I achieve this? Seems like it can be only one or the other.
new Vue({
el: "#app",
data: {
iExist:false,
iDoNotExist: true,
},
methods: {
iSignedUpforThis: function(){
console.log("step X");
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<p v-show="iExist"> i EXISTS </p>
<p v-show="iDoNotExist">
<strong> You are not found: </strong>
<form >
First name:<br>
<input type="text" name="firstname" value="Mickey">
<br>
Last name:<br>
<input type="text" name="lastname" value="Mouse">
<br><br>
</form>
<BUTTON v-on:click="iExists = iDoNotExist">
TOGGLE MY EXISTENCE
</BUTTON>
</div>
Move
iExists = iDoNotExist to a method:
methods: {
iSignedUpforThis: function(){
this.iExist = this.iDoNotExist
console.log("step X");
}
}
<button v-on:click="iSignedUpForThis">
TOGGLE MY EXISTENCE
</button>
First off to accomplish your desired result you need only one Boolean variable. Then in your method just switch between true and false. Also you have an invalid markup - there is closing tap p but no closing. That's why your example does not work.
Notice: it's bad idea to nest form tag inside p tag, so use div instead. It's considered a good practice to associate your input with it's label using label tag. Also there is shortcut for v-on:click - #click. data should be an function that returns an object, this will prevent . multiple instance to share the same object.
If you follow above recommendations you will make your code much clear and bug-less.
new Vue({
el: '#app',
data: {
isExist: false,
},
methods: {
method() {
this.isExist = !this.isExist
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<div v-show="isExist">I exist</div>
<div v-show="!isExist">
<strong>You are not found:</strong>
<form>
<label>First name:<br>
<input type="text" name="firstname" value="Mickey">
</label>
<br>
<label>Last name:<br>
<input type="text" name="lastname" value="Mouse">
</label>
</form>
</div>
<button #click="method">Toggle</button>
</div>
It might be late but I am sure it will help others. Create a component ToggleButton.js and paste the below codes.
<template>
<label for="toggle_button">
<span v-if="isActive" class="toggle__label">On</span>
<span v-if="! isActive" class="toggle__label">Off</span>
<input type="checkbox" id="toggle_button" v-model="checkedValue">
<span class="toggle__switch"></span>
</label>
</template>
<script>
export default {
data() {
return {
currentState: false
}
},
computed: {
isActive() {
return this.currentState;
},
checkedValue: {
get() {
return this.defaultState
},
set(newValue) {
this.currentState = newValue;
}
}
}
}
</script>

I have a HTML input field to enter some information:
<div id="fruitForm">
<div class="inputArea">
<label for="fruit0">Enter Fruit Name</label>
<input id="fruit0"></input>
</div>
</div>
<button #click="newInputField">Add More Fruit Input Fields</button>
<button #click="submit">Submit Fruit</button>
And then I handle that click event:
export default {
data() {
return {
}
},
methods: {
newInputField() {
//Create another input area for users to input fruits
},
submit() {
//Do something here
}
}
}
When a user selects the Add More Fruit Input Fields button, it should create a new input area so that the HTML looks like this:
<div id="fruitForm">
<div class="inputArea">
<label for="fruit0">Enter Fruit Name</label>
<input id="fruit0"></input>
</div>
<div class="inputArea">
<label for="fruit1">Enter Fruit Name</label>
<input id="fruit1"></input>
</div>
</div>
<button #click="newInputField">Add More Fruit Input Fields</button>
<button #click="submit">Submit Fruit</button>
Now, I've been using traditional DOM manipulation methods via vanilla Javascript to accomplish this... stuff like this:
const inputArea = document.getElementsByClassName('inputArea');
And then I change the id's of the input field, and then I use appendChild to add the new input field to the DOM.
So my question is: how should I be cloning this element with vuejs? I feel I'm not approaching this in the vuejs way. Should I be approaching this like a list and using v-for? Or something else?
Avoid direct DOM manipulations with Vue. You can use data property as a model for your template. The answer would be yes, you can and probably should use v-for for what you call cloning:
var demo = new Vue({
el: '#demo',
data: {
counter: 0,
inputs: [{
id: 'fruit0',
label: 'Enter Fruit Name',
value: '',
}],
},
methods: {
addInput() {
this.inputs.push({
id: `fruit${++this.counter}`,
label: 'Enter Fruit Name',
value: '',
});
}
}
});
<script src="https://unpkg.com/vue#2.5.16/dist/vue.js"></script>
<div id="demo">
<div class="inputArea" v-for="input in inputs" :key="input.id">
<label :for="input.id">{{input.label}}</label>
<input :id="input.id" v-model="input.value"></input>
</div>
<button #click="addInput">Add input</button>
</div>
So I have 2 blocks of HTML, each containing 2 input fields and when submitting the form, I want to get all values from the inputs, and then create an object from the values...
As of know I've done it with plain vanilla JS and it works as it should, however if feels like to touching the DOM a bit to much, and also are very much depending on a specific DOM struckture, and therefore I was thinking there must be a better way, the VUE way so to speak, however im a bit stuck on how to do this the VUE way, which is why posting the question here in hope of getting some useful tips :)
HTML:
<form novalidate autocomplete="off">
<div class="input-block-container">
<div class="input-block">
<input type="text" placeholder="Insert name" name="name[]" />
<input-effects></input-effects>
</div>
<div class="input-block">
<input type="email" placeholder="Insert email address" name="email[]" />
<input-effects></input-effects>
</div>
</div>
<div class="input-block-container">
<div class="input-block">
<input type="text" placeholder="Insert name" name="name[]" />
<input-effects></input-effects>
</div>
<div class="input-block">
<input type="email" placeholder="Insert email address" name="email[]" />
<input-effects></input-effects>
</div>
</div>
<button class="button button--primary" #click.prevent="sendInvites"><span>Send</span></button>
</form>
JS:
methods: {
createDataObject() {
let emailValues = document.querySelectorAll('input[type="email"]');
emailValues.forEach((email) => {
let name = email.parentNode.parentNode.querySelector('input[type="text"]').value;
if(email.value !== "" && name !== "") {
this.dataObj.push({
email: email.value,
name
});
}
});
return JSON.stringify(this.dataObj);
},
sendInvites() {
const objectToSend = this.createDataObject();
console.log(objectToSend);
//TODO: Methods to send data to server
}
}
You can provide data properties for each of your inputs if you have static content.
data: function() {
return {
name1: '',
email1: '',
name2: '',
email2: ''
}
}
Then use them in your template:
<input type="text" placeholder="Insert name" v-model="name1" />
Access in method by this.name1
Try this
<div id="app">
<h1> Finds </h1>
<div v-for="find in finds">
<input name="name[]" v-model="find.name">
<input name="email[]" v-model="find.email">
</div>
<button #click="addFind">
New Find
</button>
<pre>{{ $data | json }}</pre>
</div>
Vue Component
new Vue({
el: '#app',
data: {
finds: []
},
methods: {
addFind: function () {
this.finds.push({ name: '', email: '' });
}
enter code here
}
});
