Hide html elements in vuejs2 - vuejs2

I want to hide html elements during the initial load, by clicking a button or link i will show those html elements. I can't find a solution to hide or show the element in vuejs2 version. I can able to see few options in vuejs but i am not sure how to use those methods. Below is my component code in that i want to hide the html element(id) "Message".
<template>
<div class="row">
<div class="col-lg-12">
<label class="checkbox checkbox-inline no_indent">
<input type="checkbox" value="">Show stats
</label>
</div>
</div>
<div class="row">
<div class="col-lg-12">
<div class="panel-group">
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">List Values</h3>
</div>
<div class="panel-body">
<button type="button" id="btn1" class="btn btn-warning btn-md" v-on:click="showWorkflow">Test 1</button>
<button type="button" id="btn2" class="btn btn-danger btn-md" v-on:click="showWorkflow">Test 2</button>
<button type="button" id="btn3" class="btn btn-info btn-md" v-on:click="showWorkflow">Test 3</button>
</div>
</div>
</div>
</div>
</div>
<div class="row">
<div id="Message">Hello i am here</div>
</div>
</template>
<script>
export default {
name: 'jobs',
methods: {
showWorkflow: function (e) {
console.log(e.target.id)
}
}
}
</script>

In Vue, you use the v-if directive to conditionally render elements.
You could also use the v-show directive if you wanted to just toggle the CSS display property.
See the section in the docs on Conditional Rendering for more info.
In your specific case, make showWorkflow a data property initially set to false.
Use this as the argument for a v-if directive on the content that you want to initially hide.
Then, when you want to show the content, set showWorkflow to true:
new Vue({
el: '#app',
data() {
return {
showWorkflow: false,
}
},
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.2/vue.min.js"></script>
<div id="app">
<div v-if="showWorkflow">
Here is the workflow
</div>
<button #click="showWorkflow = true">Show Workflow</button>
</div>

How pass Image-path from tag to Vue Component

I want to pass a image path from a tag that built by Vue to vue component(MyPost):
<my-post txt="Such a great Framework, Rouzbeh Said!" url="image.png"></my-post>
I use parameter in component like this but didn't work:
<img src="{{ url }}" alt="post-picture">
My component in Vue:
<script>
Vue.component('MyPost',{
props: ['txt', 'url'],
template: `
<div class="col">
<div class="card shadow-sm">
// this line didnt work
<img src="{{ url }}" alt="post-picture">
<div class="card-body">
<p class="card-text">{{txt}}</p>
<div class="d-flex justify-content-between align-items-center">
<div class="btn-group">
<button type="button" class="btn btn-sm btn-outline-secondary">View</button>
<button type="button" class="btn btn-sm btn-outline-secondary">Edit</button>
</div>
<small class="text-muted">9 mins</small>
</div>
</div>
</div>
</div>
`
});
var app = new Vue({
el: "#app",
});
</script>
You should use :src instead of src to indicate that you have an expression and not a static text:
<img :src="url" alt="post-picture">
{{ and }} should be used only in a tag content and not in tag attributes

How can I intercept the bootstrap "data-target" event?

Elaboration on Question:
I'm using a bootstrap modal dialogue, and I only want it to work if the user is logged in.
While vue.js can make this element disappear entirely if a user is not logged in, or handle links of any kind, 'data-target' is giving me trouble.
Goal: Check if a user is logged in before activating modal. If a user is NOT logged in, I handle it somewhere else in the code (details there are not germane to this question IMO, but involve activating a completely separate modal).
If the user IS logged in, then allow the modal to be activated via 'data-target'
Problem: Currently, when a user is NOT logged in, the 'reportModalIdWithHash' is activated before the
'checkForLogin()'
Code:
<span
class="float-right text-muted smaller-font make-clickable"
data-toggle="modal"
:data-target="reportModalIdWithHash"
v-on:click="checkForLogin()"
>
Report
</span>
Note About Preferred Solution:
I'd like to have "checkForLogin()" to happen before the modal is triggered by "data-target".
While I can always make elements dissappear with Vue.js, I want the user to see the option and then when they click on it, if they're not logged in, then present a login instead of the report modal.
Is it possible to intercept and re-fire 'data-target'?
Why not use a dynamic data-target?
:data-target="`#${isLoggedIn ? 'fancy' : 'login'}-modal`"
new Vue({
el: '#app',
data: () => ({
isLoggedIn: false
}),
methods: {
handleLogin() {
// replace this with an async API call...
this.isLoggedIn = true;
// and switch modals...
['fancy', 'login'].forEach(name => $(`#${name}-modal`).modal('toggle'));
}
}
})

<button type="button" class="btn btn-primary">OK</button>

Note: this is a simple proof of concept, not production ready code:
don't use Vue + Bootstrap + jQuery as in my example (it's pretty barbaric). You're better off using BootstrapVue (and getting rid of jQuery).
You might want to use a single dynamic modal and inject the body, title and footer contents via slots. That's not always better but, in general, leads to DRY-er code at expense of readability.
With BootstrapVue, your button would look more like this:
<b-btn v-b-modal[`${isLoggedIn ? 'fancy' : 'login'}-modal`]> Open Modal</b-btn>
...or, if you want to handle it in a method:
<b-btn #click="handleOpenModal">Open modal</b-btn>
and:
methods: {
handleOpenModal() {
this.$bvModal.open(this.isLoggedIn ? 'fancy-modal' : 'login-modal');
}
}

external page load in modal view + vuejs

I am trying to open an external page in bootstrap modal view.
It is working fine if the "open Modal" button is in normal div. But if the button is inside the div, which is accessed by vuejs, modal is opening but the page is not loading anymore.
here is my code
<div id="abc">
<button type="button" class="btn btn-primary" href="http://bing.com" data-toggle="modal" data-target="#myModal">
Open modal1
</button> <!-- this modal works perfectly and load bing webpage -->
</div>
<div id="products">
<div class="row">
<div v-for="product in allproducts" class="col-md-4 col-sm-12">
Price:{{product.price}}
<button type="button" class="btn btn-primary" v-bind:href="'http://bing.com'" data-toggle="modal" data-target="#myModal">
Open Modal 2
</button> <!-- on click, modal view is opening but bing webpage is not loading-->
</div>
</div>
</div>
<!-- The Modal -->
<div class="modal" id="myModal">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<script>
$('button.btn.btn-primary').on('click', function(e) {
e.preventDefault();
var url = $(this).attr('href');
$(".modal-body").html('<iframe width="100%" height="100%" frameborder="0" scrolling="no" allowtransparency="true" src="'+url+'"></iframe>');
});
new Vue({
el: '#products',
data: {
allproducts : myJsonData,
deviceType:myDeviceType,
},
methods: {
submitValue: function(event){
},
},
});
</script>
Any idea?
Got solution: As I am calling the button with v-bind so, the trigger function should be inside method of vue js:
So i replaced button in this way
<input class="btn btn-primary" type="button" value="Click it!" v-on:click="selectProduct(product.id+'.png');" data-toggle="modal" data-target="#myModal"/>
In script we do not need $('button.btn.btn-primary').on('click', function(e) { .....} any more. instead write a method inside vue
selectProduct: function(id){
var url = "/abc.html?myselection="+id; //or anyother html page
$(".modal-body").html('<iframe width="100%" height="100%" frameborder="0" scrolling="no" allowtransparency="true" src="'+url+'"></iframe>');
}

Vue: method is not a function within inline-template component tag

I have this component:
<template>
<div class="modal fade modal-primary" id="imageModal" tabindex="-1" role="dialog" aria-labelledby="ImageLabel"
aria-hidden="true">
<div class="modal-dialog modal-lg animated zoomIn animated-3x">

<div class="modal-body">
<div class="container">
<ais-results :results-per-page="10" inline-template>
<div class="row">

<div class="card" #click="getTemplate(result)">
<img class="img-fluid" v-lazy="result.image"/>
<div class="card-body">

<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</template>
<script>
import Algolia from '#/components/algolia/menu';
export default {
components: {
"algolia-menu": Algolia,
},
data() {
return {
category: 'category',
};
},
methods: {
getTemplate(result) {
console.log(result)
}
}
}
</script>
I have a click listener on the .card div within my <ais-results> tag which calls my getTemplate method. But, whenever I click on that element, it produces this error:
imageModal.vue?8d74:85 Uncaught TypeError: _vm.getTemplate is not a
function
at click (imageModal.vue?8d74:85)
at invoker (vue.runtime.esm.js:2023)
at HTMLDivElement.fn._withTask.fn._withTask
Why is this happening? I have tried #click.native as well, but that didn't work.
The issue is that you’re using an inline template for your <ais-results> component tag, so the data references within that tag are scoped to the <ais-results> instance. This means Vue is looking for a getTemplate method on the <ais-results> component, but not finding it.
In your case, instead of directly calling getTemplate, you could emit an event with the result data and then listen for the event on the <ais-results> tag.
Below is a simplified example where clicking on the .card div in the inline template will emit a card-click event (#click="$emit('card-click', result)"). The <ais-results> tag has a listener for that event (#card-click="getTemplate"), so when the card-click event is fired, the getTemplate method will be called with the result data being passed automatically.
<ais-results :results-per-page="10" inline-template #card-click="getTemplate">
<div class="row">
<div class="col-6" v-for="result in results.slice(0, 5)" :key="result.objectID">
<div class="card" #click="$emit('card-click', result)">
...
</div>
</div>
</div>
</ais-results>

How can I display modal in modal on vue component?

My view blade like this :
<a href="javascript:" class="btn btn-block btn-success" #click="modalShow('modal-data')">
Click here
</a>
<data-modal id="modal-data"></data-modal>
If the button clicked, it will call dataModal component (In the form of modal)
dataModal component like this :
<template>
<div class="modal" tabindex="-1" role="dialog">
<div class="modal-dialog" role="document">
<!-- modal content data -->
<div class="modal-content modal-content-data">
<form id="form">
<div class="modal-body">
...
</div>
...
<button type="submit" class="btn btn-success" #click="add">
Save
</button>
...
</form>
</div>
<!-- modal content success -->
<div class="modal-content modal-content-success" style="display: none">
<div class="modal-body">
...
</div>
</div>
<!-- modal content failed -->
<div class="modal-content modal-content-failed" style="display: none">
<div class="modal-body">
...
</div>
</div>
</div>
</div>
</template>
<script>
export default{
...
methods:{
add(event){
const data = {
...
}
this.$store.dispatch('add', data)
.then((response) => {
if(response == true)
this.$parent.$options.methods.modalContent('#modal-data', '.modal-content-success')
else
this.$parent.$options.methods.modalContent('#modal-data', '.modal-content-failed')
})
.catch(error => {
console.log('error')
});
}
}
}
</script>
If response = true then modal with class = modal-content-success will appear
If response = false then modal with class = modal-content-failed will appear
I want if response = false, modal with class = modal-content-data still showing. So modal with class = modal-content-failed appears in modal with class class = modal-content-data
How can I do that?
How to order that when response = false, modal with class = modal-content-data still appear?
Please help me
As i can see you are using bootstrap, this worked for me:
<template>
<div>
<div id="modal-example" class="modal" tabindex="-1" role="dialog">
...insert rest of code here as is in your example
</div>
</div>
</template>
And then in your href link tag:
<a href="javascript:void(0)" class="btn btn-block btn-success" data-target="#modal-example" data-toggle="modal">
Show Modal
</a>
