I'm making age verification on page. When click #mbgo, page must open a page. But it is not opening. It must open #btn_AddToBasket's link
The problem is in function
$("#mbgo").click( function() {
window.location = link.href;
});
The variable link in undefined, so your code should be
window.location = $("#btn_AddToBasket").attr("href");

Currently learning Vue and Axios, and i'm trying to get data from an API and display it within an HTML card, but it seems that it tries to display the data before getting it from the API and then nothing renders.
<script type="text/javascript">
const {createApp} = Vue;
const data = null;
const error = null;
const app = createApp({
data(){
return{
movieID: localStorage.getItem("movieID"),
movieDetail: null
}
},
methods:{
getMovieDetail(){
var config = {
method: 'get',
url: 'https://api.themoviedb.org/3/movie/'+localStorage.getItem("movieID"),
headers: {
'Authorization': 'Bearer'
}
};
axios(config);
app.movieDetail = respuesta.data;
document.getElementById("tituloPeli").innerHTML = app.movieDetail.title
.then(function (response) {
app.movieDetail = response.data;
})
.catch(function (error) {
console.log(error);
});
}
},
mounted(){
this.getMovieDetail();
}
}).mount("#contenedor");
</script>
<div id="contenedor">
<div class="container-xxl my-4">
<h1>Data from movie with ID {{movieID}}</h1>
</div>
<div class="container">
<div class="row align-items-start">
<div class="col-12">
<div class="card my-2">
<img class="card-img-top" :src="'https://image.tmdb.org/t/p/w600_and_h900_bestv2' + movieDetail.poster_path">
<div class="card-body">
<h6 class="card-title">
{{movieDetail.title}}
</h6>
</div>
</div>
</div>
</div>
</div>
</div>
Highly appreciated if you could help me, thank u so much
The key is to not render the data until it's ready. This is called conditional rendering and can be done using the v-if directive
<h6 v-if="movieDetail?.title" class="card-title">
{{movieDetail.title}}
</h6>
Along with standard javascript optional chaining you can guarantee an object and it's properties are all defined before rendering it in your template.
good day; kindly need your support to finalize this issue i try to make infinite scrolle using laravel and vue.js and my proplem is get in finite loop to set request to data base and mu applocation hang up this is my code x component
<template>
<div class="container" style="margin-top:50px;">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header"><strong> Laravel Vue JS Infinite Scroll - ItSolutionStuff.com</strong></div>
<div class="card-body">
<div>
<p v-for="item in list">
<a v-bind:href="'https://itsolutionstuff.com/post/'+item.slug" target="_blank">{{item.title}}</a>
</p>
<infinite-loading #distance="1" #infinite="infiniteHandler"></infinite-loading>
</div>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
mounted() {
alert()
console.log('Component mounted.')
},
data() {
return {
list: [],
page: 1,
};
},
methods: {
infiniteHandler($state) {
let vm = this;
this.$http.get('/Services?page='+this.page)
.then(response => {
return response.json();
}).then(data => {
$.each(data.data, function(key, value) {
vm.list.push(value);
});
$state.loaded();
});
this.page = this.page + 1;
},
},
}
</script>
this is my route
Route::get('/Services', 'ServicesController#Services');
Problem 1
You are binding to the distance property wrong.
Solution
Instead of <infinite-loading #distance="1" #infinite="infiniteHandler"></infinite-loading>
it should be
<infinite-loading :distance="1" #infinite="infiniteHandler"></infinite-loading>
Problem 2
In the code, this.page is being incremented before $http.get is resolved.
This may result in unintentional side effects.
Solution
As per the example in docs vue-infinite-loading hacker news example you should be incrementing the page after data is loaded.
I'm trying to validate a simple form that contains two fields:
A select box
A file field
If one of the fields aren't filled in, a div (containing an error label) should be rendered next to the corresponding input field.
The problem: My 'error divs' aren't rendered when pushing data to the errors object (if the form is invalid).
Please note my console.log statement, that tells me that my error object has a key 'file' and a key 'selectedSupplier'.
Side note: I'm following this example: https://v2.vuejs.org/v2/cookbook/form-validation.html
Differences are, that I'd like to show error labels next to the corresponding field and that I'm setting errors in my errors object, instead of a simple array. So what could I be doing wrong?
Thanks.
This is my Main.vue file:

Apparently I had to use v-show instead of v-if, because v-if would be 'lazy' and will not render my error-div when the errors var gets filled.
It's working now, but not 100% sure if this is the best way, as I found another tutorial where v-if is used for form validation.(https://medium.com/#mscherrenberg/laravel-5-6-vue-js-simple-form-submission-using-components-92b6d5fd4434)
I was getting the same error, this is how I solved the problem,
<div v-if="errors.field1.length > 0 ? true : false"> // true or false
If you fix the code like this it will work
The reason might because the way you reassign object is not reactive, which not trigger v-if to re-calculate
this.errors.selectedSupplier = 'Supplier required';
this.errors.file = 'File required';
If you still want to use v-if , try change to this approach
this.errors = {...this.errors, selectedSupplier: 'Supplier required' }
this.errors = {...this.errors, file: 'File required' }
The way I handle my errors with VueJS is through lists and their length attribute.
I have an errors object in my data that looks like this:
errors: {
field1: [],
field2: [],
}
Then, when I submit the form, I will:
Empty all the lists for the errors (ie clearing the previous errors)
.push() new errors in the right lists (and .push() makes the Vue reactive)
Finally, in my form, my respective errors divs are displayed based on the length of the list:
<div class="error" v-if="errors.field1.length > 0">
use a v-for to display all the errors from the list
</div>
Hope it helps
I am trying to do a very simple vue example and it won't display. I've done similar things before, but this won't work.
It is an extremely simple task list. It is an input with a submit button that adds an item to a list. For some reason the component does not render at all. I am very lost am supposed to give a presentation on vue. I was hoping to use this as an example.
I'm really not sure what else to say about this, but stack overflow won't let me submit this without typing more information about the issue.
<div id="app">
<task-list></task-list>
</div>
Vue.component('task-list-item', {
props: ["task"],
template: '#task-list-item-template'
})
Vue.component('task-list', {
data: function () {
return {
taskList: [],
newTask: ''
}
},
methods: {
addTask: function () {
var self = this;
if (self.newTask !== ""
&& self.newTask !== null
&& typeof self.newTask !== "undefined") {
this.taskList.push(self.newTask);
this.newTask = "";
}
}
},
template: '#task-list-template'
})
new Vue({
el: '#app',
data: function () {
return {
}
}
})
<script id="task-list-template" type="text/x-template">
<input v-model="newTask" />
<button v-on:click="addTask()">Add Task</button>
<ul>
<task-list-item v-for="taskItem in taskList"
v-bind:task="taskItem">
</task-list-item>
</ul>
</script>
<script id="task-list-item-template" type="text/x-template">
<li>{{task}}</li>
</script>
I am getting no error messages of any kind.
I think the problem is there should be only 1 child under <script id="task-list-template" type="text/x-template"></script>. In task-list-template, you have multiple children. Try to wrap them in 1 div
<script id="task-list-template" type="text/x-template">
<div>
<input v-model="newTask" />
<button v-on:click="addTask()">Add Task</button>
<ul>
<task-list-item v-for="taskItem in taskList"
v-bind:task="taskItem">
</task-list-item>
</ul>
</div>
</script>
Demo on codepen
According to A Single Root Element
Every component must have a single root element
To fix you can do some thing like:
<script id="task-list-template" type="text/x-template">
<div>
<input v-model="newTask" />
<button v-on:click="addTask()">Add Task</button>
<ul>
<task-list-item v-for="taskItem in taskList" v-bind:task="taskItem">
</task-list-item>
</ul>
</div>
</script>
I try to call different elements(3 html pages like home, login and chat page) in spa with a v-show/v-if with von:click v-button.
Does somebody has a clear example?
new Vue({
el: '#app',
data() {
return {
page: 'login'
}
},
methods: {
loginClick() {
this.page = 'home'
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.min.js"></script>
<div id="app">
<div v-if="page === 'login'">
<button #click="loginClick">Login</button>
</div>
<div v-if="page === 'home'">
home page
go to chat
</div>
<div v-if="page === 'chat'">
chat page
</div>
</div>
