Vue - Clear true false toggles from out side a loop - vue.js

I am relatively new to Vus.js and vanilla js, Im looking for some help. I have a loop where filters are toggled between false and true depending on the criteria. I have a button outside of all the vue loops that I would like to use to clear all the toggles - set all the data back to false.
I am using axios and a json file for my data. Theere are three filess I am working with filters.json, filters.js and the html
Thanks in advance for you help

.then(response => {
// JSON responses are automatically parsed.
this.shopFilters = response.data;
})

// my attempt at clearing filter
clearAll: function(filter) {

:class="{'active' : option.selected}">

I got a fix for this
clearAll: function() {
for (var i = 0; i < this.shopFilters.length; i++) {
var filter = this.shopFilters[i];
filter.buttonActive = false;
filter.filterVisible = false;
for (var j = 0; j < filter.values.length; j++) {
var option = filter.values[j];
option.selected = false;
}
}
}, // end clearAll

Computed instead of v-if in v-for

I have a page that displays the birthdays per month of the teams.
With two buttons that allow you to change the current month.
The solution with v-if works fine but since it is not a good practice I try with a computed property.
<tr v-for="birthday in birthdays" :key="birthday.name" v-if="birthday.month[month]">
<td class="px-6 py-4 whitespace-nowrap">
<div class="flex items-center">
<div class="text-sm font-medium text-gray-900">
{{ birthday.name }}
Sample data of birthdays :
[
{
"month": {
"1": false,
"2": false,
"3": true,
"4": false,
"5": false,
"6": true,
"7": true,
"8": false,
"9": true,
"10": false,
"11": true,
"12": false
},
"name": "team 2"
},
{
"month": {
"1": false,
"2": false,
"3": true,
"4": false,
"5": false,
"6": true,
"7": true,
"8": false,
"9": true,
"10": false,
"11": true,
"12": false
},
"name": "team 1"
}
]
and my code with the computed property :
export default {
data() {
return {
birthdays: {},
month: false,
};
},
async asyncData({ $axios, store }) {
let email = store.state.auth.user.email;
let month = new Date().getMonth() + 1;
let { data } = await $axios.get("/birthday/?email=" + email);
return { birthdays: data, month: month };
},
methods: {
nextMonth() {
if (this.month === 12) {
this.month = 1;
} else this.month = this.month + 1;
},
previousMonth() {
if (this.month === 1) {
this.month = 12;
} else this.month = this.month - 1;
},
},
computed: {
fiestas: function () {
let birthdays = this.birthdays;
for (let team in birthdays) {
if (!birthdays[team].month[this.month]) {
birthdays.splice(team, 1);
}
}
return birthdays;
},
},
};
This works for the current month (with a few ms or we see the data before the computed) but when we change the month nothing works like birthdays has been modified.
Maybe in my case it is better to stay on a v-if?
splice modifies array in-place (instead of creating new array) so your fiestas computed is changing this.birthdays array...
Compute should never have a side-effects. Do this instead:
computed: {
teamsWithBirthdayInCurrentMonth: function () {
return this.birthdays
.filter(team => team.month[this.month])
.map(team => team.name)
},
},

Vuejs get dynamic form values

I have select and input component with made by buefy. Everything is ok till I realize how can I get the data.
I'm sort of new on vuejs. So I will be glad if you help me out.
I'm getting dynamic form from backend
So my question is how can get values these inputs and submit to backend again with getOffer() methot.
Here is my codes;
Input.vue
<template>
<b-field :label="fieldLabel">
<b-input
:name="inputName"
:type="inputType"
:maxlength="inputType == 'textarea' ? 200 : null"
></b-input>
</b-field>
</template>
<script>
export default {
name: "Input",
props: {
inputType: {
type: String,
required: true,
default: "text",
},
inputName: {
type: String,
required: true,
},
fieldLabel: {
type: String,
required: true,
}
}
};
</script>
Home.vue
<template>
<div class="container is-max-desktop wrapper">
<div v-for="element in offer" :key="element.id">
<Input
v-model="element.fieldValue"
:value="element.fieldValue"
:fieldLabel="element.fieldLabel"
:inputType="element.fieldType"
:inputName="element.fieldName"
v-if="element.fieldType != 'select'"
class="mb-3"
/>
<Select
v-model="element.fieldValue"
:fieldLabel="element.fieldLabel"
:options="element.infoRequestFormOptions"
:selectName="element.fieldName"
v-if="element.fieldType == 'select'"
class="mb-3"
/>
</div>
<b-button type="is-danger" #click="getOffer()">GET</b-button>
</div>
</template>
<script>
import axios from "axios";
import Select from "../components/Select.vue";
import Input from "../components/Input.vue";
export default {
name: "Home",
data() {
return {
offer: [],
};
},
components: {
Select,
Input,
},
methods: {
getOfferForm() {
axios({
method: "get",
url: `/GETDYNAMICFORM`,
})
.then((response) => {
this.offer = response.data;
})
.catch(() => {
this.$buefy.toast.open({
duration: 3000,
message: "oops",
position: "is-bottom",
type: "is-danger",
});
});
},
getOffer() {
console.log(this.offer);
},
},
created() {
this.getOfferForm();
},
};
</script>
Example Dynamic Form Response like;
[
{
"id": 58,
"fieldLabel": "Name Surname",
"providerLabel": "Name Surname",
"fieldName": "nmsrnm",
"fieldType": "text",
"fieldValue": null,
},

"fieldType": "email",
"fieldValue": null,
},
{

"fieldLabel": "Budget",
"providerLabel": "Budget",
"fieldName": "bdget",
"fieldType": "select",
"fieldValue": "",
"infoRequestFormOptions": [
{
"id": 1,
"orderNum": 0,
"optionValue": 0,
"optionText": "Select",

"orderNum": 1,
"optionValue": 1,
"optionText": "10-30",

}
]
}

Search Builder extension of DataTables does not save values

I am using the SearchBuilder extension to filter data.
Because I am also using sever-side processing, I force a search only when the user presses the enter key, like example.
But when I click button ">" to add new criteria, the previous value is empty.
Any suggestion for me?

v-on not working with v-for which is created dynamically

I am looping a bit complex data using v-for. I have a text box to add new data set to it. Each cell in the table toggles to edit mode on double clicking it. It works fine when there are no new entries added. But when I add a new entry using 'Add a category' textbox, the double click is not working properly. Here is jsfiddle. Can someone help on this?

When adding properties to an object you run into what Vue's docs call Change Detection Caveats
In relation to your code what this means is that this part
addSubCategory: function(category) {
for (var i = 3; i > 0; i--) {
this.expectedMonthlyBudget[category][this.newCategory[category]] = {
won't add the new object to Vue's change detection flow.
You have to use Vue.set (or its alias, this.$set):
addSubCategory: function(category) {
for (var i = 3; i > 0; i--) {
this.$set(this.expectedMonthlyBudget[category], this.newCategory[category], {
"2020": {
"1": {
"value": 0,
"editing": false
},
"2": {
"value": 0,
"editing": false
},
"3": {
"value": 0,
"editing": false
}
}
});
}
this.newCategory[category] = '';
},
Note that I've also initialized the "editing" property (instead of creating it inside toggleEditingMoney method via element.editing = true;), as this is also necessary so Vue is aware of its presence.

Filter on nested (recursive) data ( Vue 2 )

Here is an example of my JSON data :
"data":[
{
"id":01,
"name":"test",
"parent_id":null,
"children":[
{
"id":15,
"name":"subChild",
"parent_id":21,
"children":[
{
"id":148,
"name":"subSubChild",
"parent_id":22,
"children":[
....
]
}
]
}
]
},
I would like to filter this level by level. I have made this method :
computed: {
filteredData: function () {
let filterData = this.filter.toLowerCase()
return _.pickBy(this.data, (value, key) => {
return _.startsWith(value.name.toLowerCase(), filterData)
})
},
This work for only the first "level" and I tried several solutions but none worked for children.
So, I would like to be able to filter by several levels.
If you have an idea!
Thank you
A recursive function could come in handy for this particular purpose.
Try the following approach, and for better view, click on Full page link next to the Run code snippet button down below.
new Vue({
el: '#app',
data() {
return {
filter: '',
maintainStructure: false,
data: [{
"id": 01,
"name": "test",
"parent_id": null,
"children": [{
"id": 15,
"name": "subChild",
"parent_id": 21,
"children": [
{
"id": 148,
"name": "subSubChild",
"parent_id": 22,
"children": []
},
{
"id": 150,
"name": "subSubChild3",
"parent_id": 24,
"children": []
}
]
}]
}]
}
},
methods: {
$_find(items, predicate) {
let matches = [];
for (let item of items) {
if (predicate(item)) {
matches.push(item);
}
else if (item.children.length) {
let subMatches = this.$_find(item.children, predicate);
if (subMatches.length) {
if (this.maintainStructure) {
matches.push({
...item,
children: subMatches
});
}
else {
matches.push(subMatches);
}
}
}
}
return matches;
},
filterBy(item) {
return item.name.toLowerCase().startsWith(this.filter.toLowerCase());
}
},
computed: {
filteredData() {
return this.$_find(this.data, this.filterBy);
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<div>
<label>Filter by <code>item.name</code>:</label>
<input v-model.trim="filter" placeholder="e.g. subsub" />
</div>
<div>
<label>
<input type="checkbox" v-model="maintainStructure" /> Maintain structure
</label>
</div>
<hr />
<pre>{{filteredData}}</pre>
</div>
Note that I'm prefixing the function with $_ to sort of mark it as private function (as recommended in this Style Guide) since we're not going to invoke it anywhere else.
