I'm using Vuejs and dataTable for one of my project. I make an Ajax call and push data into an array. After that I use v-for to loop the data in the <tr> tag. Most of the time it doesn't work. The table loads as soon as the page has finished loading.. it takes a bit of time to receive the ajax data. Here is the output. It says no data available in the table
So the serch option doesn't work properly. I thought to use a setTimeout function (which was a bad idea) to load the table after a bit of time. What would be the proper way to do it? Sharing the code :
new Vue({
el: '#app',
data: {
entries: [],
},
methods:{
getData(){
var route = '/admin/temporary-enrolled-students';
this.$http.get(route).then((response)=>{
for(var i = 0; i< response.data.length;i++)
{
this.entries.push({
scId: response.data[i].id,
name: response.data[i].user.name,
phone: response.data[i].user.phone,
email: response.data[i].user.email,
courseId: response.data[i].course.id,
courseName: response.data[i].course.course_title,
expiryDate: response.data[i].expiry_date,
shares: response.data[i].number_of_shares,
expired: (response.data[i].expired == 1),
enrollDate: response.data[i].created_at
})
}
})
},
},
mounted(){
this.getData();
},
});
//data table
$(function () {
setTimeout(()=> {
$("#temp-enroll").DataTable({
"paging": true,
"ordering": false,
"info": true,
"autoWidth": false
});
},1000);
});
in blade:
Ok I tried this and working exactly what I have wanted. Thanks everyone for supporting.
new Vue({
el: '#app',
data: {
entries: [],
},
methods:{
getData(){
var route = '/admin/temporary-enrolled-students';
this.$http.get(route).then((response)=>{
for(var i = 0; i< response.data.length;i++)
{
this.entries.push({
scId: response.data[i].id,
name: response.data[i].user.name,
............................
......................
enrollDate: response.data[i].created_at
})
}
}).then(()=>{
$("#temp-enroll").DataTable({
"paging": true,
"ordering": false,
"info": true,
"autoWidth": false
});
});
},
},
mounted(){
this.getData();
},
});
I think someone mentioned that a computed property is the way to go, and that is what I would recommend as well.
The reason why is that as soon as your template makes a reference to the computed property, this triggers your ajax call. The page will then render any other available elements, and when your ajax call returns, it will then render the data it received. No special action in code is required.
Anyway, here is what it would look like...
In your html, as an example...
<table>
<tr v-for="item in serverData">
<td>{{item.name}}</td>
<td>{{item.someOtherValue}}</td>
</tr>
</table>
export default {
name: 'pets',
data () {
return {
}
},
computed: {
serverData: function() {
// ajax call using axios - returns a json array []
axios.get("http://localhost:8080/getSomeData")
.success(function(data) {
return data;
};
}
}
}
Notice the return in the success promise returned from the ajax call - there is no need to store the data to another variable (and you should definitely not have to loop through it like the noob coder example above shows. Do that on the server, return an array ready to render - if it isn't your web service, then write your own that calls the original and do the data manipulation there).
The parts of your template that reference the computed value will render after the data arrives - there is no need to watch it.
Hope this helps!
Vue is the bomb!

You could try watch property https://v2.vuejs.org/v2/guide/computed.html#Watchers. From the doc:
While computed properties are more appropriate in most cases, there
are times when a custom watcher is necessary. That’s why Vue provides
a more generic way to react to data changes through the watch option.
This is most useful when you want to perform asynchronous or expensive
operations in response to changing data.

I am trying to add multiple product in the cart. I am using vuejs and django rest framework. My problem is: When I add a product into the cart it added successfully But when I add another product it doesnt add. It adds the same product again and again.
For example:
I have three products named "A" and "B" and "C". I added "A". Then i try to add "C" in the cart. But it stills adds "A" in the cart. I cleared the session and tried again still add the "A" product if I try to add "C" product first. It always add "A" product.
Here is my store/index.js:
import { createStore } from 'vuex'
export default createStore({
state: {
cart: {
items: []
},
isAuthenticated: false,
token: '',
isLoading: false,
},
mutations: {
initializeStore(state){
if(localStorage.getItem('cart')){
state.cart = JSON.parse(localStorage.getItem('cart'))
}
else{
localStorage.setItem('cart', JSON.stringify(state.cart))
}
},
addToCart(state, item) {
let exists = state.cart.items.filter(i => i.product.id === item.product.id)
if (exists.length){
exists[0].quantity = parseInt(exists[0].quantity) + parseInt(item.quantity)
}
else{
state.cart.items.push(item)
}
localStorage.setItem('cart', JSON.stringify(state.cart))
}
},
actions: {
},
modules: {
}
})
Here is my add to cart page and code:

I am new in vue js. I am trying to build this projetc so that i can learn. But this issue is eating my brain. I tried to use find function in sotre/index.js. It solved my problem though but if i clear the cookies and try to add product it gives me error.
is there any solution for me?
Thanks in advance.
I'm learning Vue JS. I'm using el-table to display my data as follows:
el-table data
Basically, I'm creating a function for a button's clicking event that contains parameter using properties of the row in the table (scope.row.id) in the code:
<el-table-column align="center" prop="id" label="Chức năng" width="150">
<template slot-scope="scope">
<el-button
type="primary"
icon="el-icon-switch-button"
#click="searchImportForm(scope.row.id)"
></el-button>
</template>
</el-table-column>
Normally it works fine. However, I've recently added a new feature to the table which is the "search" feature. There is a new text box for the user to input a keyword and the table returns all the information containing that keyword.
Now, when I press the button, the function does not work anymore. And my problem is that the error tells "Cannot read property "id" of undefined".
Does anyone how to handle with dynamic data table like this ??
Update: Here is the full code of my problem

I am not getting any console error as well.
This is what i have tried so far.
Can you guys please have a look at this!
The problem is that #change is not trigger when you choose the same file. The simplest solution is reset value of input when you click delete
this.$refs.fileToUpload.value = '';
new Vue({
el: "#app",
data() {
return {
form: {
message: '',
fileurl: ''
},
loading: false
}
},
methods: {
uploadImage(event) {
this.form.fileurl = 'uploaded!'
},
deleteFile(furl) {
this.form.fileurl = ''
this.$refs.fileToUpload.value = '';
}
}

You need to clear you input field first.
Update your upload method with this.
uploadImage(event) {
this.form.fileurl = 'uploaded!'
this.success = false
this.$nextTick(() => {
this.success = true
})
Have a look at this working demo

Following is the code, I define a my data in Vue as below:
{
result: {
name: 'user A',
age: 20,
male: true
},
showDetails: true
}
There are several filter/computed/methods in the view will do the result formatting.
The problem is even I just change the value of the showDetailds, the methods and filters defined for the result will be triggered as well.
May I know any issue in my code ? Or it's the natural of Vue.js (I don't believe.) ?
function countTheCall(key) {
let counter = document.getElementById(key)
if (!counter) {
let container = document.getElementById('statList')
var item = document.createElement('li')
item.innerHTML = `${key}: <span id='${key}'>0</span>`
container.appendChild(item)
counter = document.getElementById(key)
}
counter.innerText = _.parseInt(counter.innerText) + 1
}
var vm = new Vue({
el: '#app',
data() {
return {
result: {

},

}

This is natural to Vue.
Methods & Filters run on every DOM re-render.
This is why it's best to use Computed whenever possible - these re-run only on change of connected properties.
I want to make pagination for my table but, when I run, my data does not appear anything. I am confused my code which is wrong perhaps here anyone can help me.
var newVue = new Vue({
el: '#app',
data: {
items: [
{ name: "item #1" }, { name: "item #2" }, { name: "item #3" }, { name: "item #4" },
{ name: "item #5" }, { name: "item #6" }, { name: "item #7" }, { name: "item #8" },
{ name: "item #9" }, { name: "item #10" }, { name: "item #11" }, { name: "item #12" }
],
start: 0,
limit: 2,
pagination: null,
total: 12
},
computed: {
filtered: function(){
return this.items.slice(0, this.limit)
}
},
mounted: function() {
this.limit = parseInt(this.pagination);
},
watch: {
pagination: function() {
this.limit = parseInt(this.pagination);
if(this.limit != this.start && this.start > 0)
this.start = parseInt(this.pagination);
this.limit = this.start + parseInt(this.pagination);
}
},
methods: {
paginate: function(direction) {
if(direction === 'next') {
this.start += parseInt(this.pagination);
this.limit += parseInt(this.pagination);
}
else if(direction === 'back') {
this.limit -= parseInt(this.pagination);
this.start -= parseInt(this.pagination);
}
},
},
filters: {
paginate: function(array, start, limit) {
return array.slice(start, limit);
}
}
});

There are few problems with your code, after removing those your code works as can be seen here in fiiddle.
You dont need | paginate with v-for as filtered is computed property which will give you paginated result
<tbody>
<tr v-for="item in filtered | paginate">
<td>{{ item.name }}</td>
</tr>
</tbody>
in filtered you needed to pass correct params in slice method.
computed: {
filtered: function(){
return this.items.slice(this.start, this.limit)
}
},`
