I have a filter dropdown in the header and when users apply the filters I want to run the assigned function according to their choices but I couldn't run it, I got "... is not a function" error.
Also, even if I solve this problem, I will probably have problems in applying more than one filter at the same time, I would be very grateful if anyone could offer a solution in the form of applying filters in multiple ways.
Example Object:
const filters = [
{
section: 'Call Types',
slug: 'call-types',
type: 'multiselect',
options: [
{
label: 'Inbound',
slug: 'inbound',
value: true,
func: (data) =>
data.items.filter((item) => {
return item.className === 'ib'
}),
},
{
label: 'Outbound',
slug: 'outbound',
value: true,
func: (data) =>
data.items.filter((item) => {
return item.className === 'ob'
}),
},
],
},
{
section: 'Data Types',
slug: 'data-types',
type: 'multiselect',
options: [
{
label: 'Sentiment',
slug: 'sentiment',
value: false,
func: (data) =>
data.items.filter((item) => {
return item.d1 === 1
}),
},
{
label: 'Capture Fails',
slug: 'capture-fails',
value: false,
func: (data) =>
data.items.filter((item) => {
return item.d2 > 0.5
}),
},
{
label: 'Audio Notes',
slug: 'audio-notes',
value: false,
func: (data) =>
data.items.filter((item) => {
return item.d1 === 1 && item.d2 > 0.5
}),
},
],
},
{
section: 'Others',
slug: 'others',
type: 'singleselect',
options: [
{
label: 'Show All Agents',
slug: 'show-all-agents',
value: true,
func: (data) =>
data.items.filter((item) => {
return item
}),
},
],
},
]
exports.filters = filters
And here is the method I'm trying to run when users click to "Filter" button.

I want to sum every existing and added value to a total sum, which I can always see.
I'm kinda struggling with how to include my existing values and those I want to add afterward.
In IncomeList I have two inputs. One for the incomeReason and with the other I can add the value (newIncomeValue). Every Item in my List contains an id. With sumValue I want to display the total amount, but I'm not sure how to do it
It looks like this:
IncomeItem.vue
<template>
<div class="income-item">
<div class="income-item-left">
<div v-if="!editing" #dblclick="editincome" class="income-item-label"
:class="{ completed : completed }">{{ title }}</div>
</div>
<div class="income-item-right"> {{ value }} </div>
<div class="remove-item" #click="removeincome(income.id)">
×
</div>
</div>
</template>
<script>
export default {
name: 'income-item',
props: {
income: {
type: Object,
required: true,
},
checkAll: {
type: Boolean,
required: true,
}
},
data() {
return {
'id': this.income.id,
'title': this.income.title,
'value': this.income.value,
'completed': this.income.completed,
'editing': this.income.editing,
'beforeEditCache': '',
}
},
watch: {
checkAll() {
// if (this.checkAll) {
// this.completed = true
// } else {
// this.completed = this.income.completed
// }
this.completed = this.checkAll ? true : this.income.completed
}
},
directives: {
focus: {
inserted: function (el) {
el.focus()
}
}
},
methods: {
removeincome(id) {
this.$emit('removedincome', id)
},
}
}
</script>

}
},

return this.incomes.filter(income => !income.completed).length
},

return this.remaining != 0

var total = parseInt(document.getElementsByClassName('newIncomeValue').value)

this.newIncome = ''
this.newIncomeValue = ''
this.this.idForincome++
},
removeincome(id) {
const index = this.incomes.findIndex((item) => item.id == id)
this.incomes.splice(index, 1)
},
checkAllincomes() {
this.incomes.forEach((income) => income.completed = event.target.checked)
},
clearCompleted() {
this.incomes = this.incomes.filter(income => !income.completed)

const index = this.incomes.findIndex((item) => item.id == data.id)
this.incomes.splice(index, 1, data)
},
//Same for Value
addValue() {
if (this.newIncomeValue.trim().length == 0) {
return
}
this.incomes.push({
id: this.idForincome,

value: this.newIncomeValue,
completed: false,
})
this.newIncome = ''
this.newIncomeValue = ''
this.this.idForincome++

}

</script>
If you want to sum the value property of your incomesFiltered, you can use reduce in your computed:
sumValue() {
return this.incomesFiltered.reduce((a, c) => a + c.value, 0);
}
I'm trying to create a checkbox select only one.
<div id="app">
<div v-for="(question, index) in questions">
<input type="checkbox" value="question.value" v-model="additional_grouped" #change="uniqueCheck"> {{question.title}}
</div>
{{ result }}
</div>
My JS looks like the following:
new Vue({
el: '#app',
data() {
return {
additional: [],
additional_grouped: [],
questions: [
{
title: 'A',
value: 0
},
{
title: 'B',
value: 1
},
{
title: 'C',
value: 2
}
]
}
},
computed: {
result: function(){
return this.additional.concat(this.additional_grouped);
}
},
methods: {
uniqueCheck(e){
console.log(e)
this.additional_grouped = [];
if (e.target.checked) {
this.additional_grouped.push(e.target.value);
}
}
}
});
This is the old result.
I'm trying to get results like this.
I can do this by not the v-for method, but I want to do it this way. Because I have a lot of data, How can I checked value in v-for?
Here is my pen: enter link description here
You are missing the value binding (:value), here's your example fixed:
new Vue({
el: '#app',
data() {
return {
additional: [],
additional_grouped: [],
questions: [
{
title: 'A',
value: 0
},
{
title: 'B',
value: 1
},
{
title: 'C',
value: 2
}
]
}
},
computed: {
result: function(){
return this.additional.concat(this.additional_grouped);
}
},
methods: {
uniqueCheck(e){
this.additional_grouped = [];
if (e.target.checked) {
this.additional_grouped.push(e.target.value);
}
}
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<div v-for="(question, index) in questions">
<input type="checkbox" :value="question.value" v-model="additional_grouped" #change="uniqueCheck"> {{question.title}}
</div>
{{ result }}
</div>
Documentation
uses :value="question.value" instead of value="question.value"
new Vue({
el: '#app',
data() {
return {
additional: [],
additional_grouped: [],
questions: [
{
title: 'A',
value: 0
},
{
title: 'B',
value: 1
},
{
title: 'C',
value: 2
}
]
}
},
computed: {
result: function(){
return this.additional.concat(this.additional_grouped);
}
},
methods: {
uniqueCheck(e){
this.additional_grouped = [];
if (e.target.checked) {
this.additional_grouped.push(e.target.value);
}
}
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<div v-for="(question, index) in questions">
<input type="checkbox" :value="question.value" v-model="additional_grouped" #change="uniqueCheck"> {{question.title}}
</div>
{{ result }}
</div>
If you want to get an array of the values of checked boxes, you should just do this
<div id="app">
<div v-for="(question, index) in questions" :key="index">
<input type="checkbox" v-model="question.checked"> {{question.title}}
</div>
{{ result }}
</div>
and
new Vue({
el: '#app',
data() {
return {
questions: [
{
title: 'A',
value: 0
},
{
title: 'B',
value: 1
},
{
title: 'C',
value: 2
}
]
}
},
computed: {
result: function(){
return this.questions.filter(q => q.checked).map(q => q.value)
}
}
});
I'm making a dynamic admin panel with crud generator with the help of laravel and vue.
I have a table where I'm loading data asynchronously from API. There is an is_featured column in my table which I want to be a switch. So that the user can change the value from the table page instead of going to edit page.
To generate my entire table there is a configuration object that contains which fields to show and the type of that field and other metadata. In the configuration object, there is a field named prerender which is responsible to prerender fields that require calling other API or some editable fields like select dropdown or switch.
To make switch and select fields work, I have an empty object named fieldData.
When a field with type: boolean and prerender: true is found, my code will initialize a property with field.name as property name in field data and fill it with the corresponding values under that field name
this.fieldData[field.name] = {};
this.tableData.forEach(
data => (this.fieldData[field.name][data.id] = data[field.name])
);
BUT THE SWITCH AND SELECT ARE NOT WORKING HERE
So I need help.

I guess this is a reactive issue. The value of dict and actually not affecting the feildData dict.
changes -
this.fieldData[field.name] = {};
replace this with
self.$set(self.fieldData,field.name,{});
and
this.fieldData[field.name][data.id] = data[field.name] // to
//Replace
self.$set(self.fieldData[field.name],data.id, data[field.name]);
I think this will fix the issue.Instead of using = use $set for value assignment.

I want to add checkboxes to Vuejs Treeview. So I added a checkbox to the template as this code:
<script type="text/x-template" id="item-template">
<li>
<input type="checkbox" id="checkbox">
<span
:class="{bold: isFolder}"
#click="toggle"
#dblclick="changeType">
{{ model.name }}
<span v-if="isFolder">[{{ open ? '-' : '+' }}]</span>
</span>
<ul v-show="open" v-if="isFolder">
<item
class="item"
v-for="(model, index) in model.children"
:key="index"
:model="model">
</item>
</ul>
</li>
</script>
But I don't know how to link those checkboxes to a model like this example. Please help! Thank you very much!
I think the simplest way to do that is by using VueX.
The store has a common variable for all checkBoxes accessible from everywhere.
When you click on a checkbox, it update the store.
https://jsfiddle.net/u91mxc58/14/
const store = new Vuex.Store({
state: {
checkBoxes:[],
},
mutations: {
updateCheckBoxes(state, value) {
state.checkBoxes = value;
}
}
})
// demo data
var data = {
name: 'My Tree',
children: [
{ name: 'hello' },
{ name: 'wat' },
{
name: 'child folder',
children: [
{
name: 'child folder',
children: [
{ name: 'hello' },
{ name: 'wat' }
]
},
{ name: 'hello' },
{ name: 'wat' },
{
name: 'child folder',
children: [
{ name: 'hello' },
{ name: 'wat' }
]
}
]
}
]
}
// define the item component
Vue.component('item', {
template: '#item-template',
props: {
model: Object,
},
data: function () {
return {
open: false
}
},
computed: {
isFolder: function () {
return this.model.children &&
this.model.children.length
},
checkBoxes: {
// accesseur
get: function () {
return store.state.checkBoxes;
},
// mutateur
set: function (newValue) {
store.commit('updateCheckBoxes', newValue);
}
}
},
methods: {
toggle: function () {
if (this.isFolder) {
this.open = !this.open
}
},
changeType: function () {
if (!this.isFolder) {
Vue.set(this.model, 'children', [])
this.addChild()
this.open = true
}
},
addChild: function () {
this.model.children.push({
name: 'new stuff'
})
}
}
})
// boot up the demo
var demo = new Vue({
el: '#demo',
data: function() {
return {
treeData: data
};
},
computed: {
checkBoxes() {
return store.state.checkBoxes;
}
}
})
