Select box on change event in Bootstrap Modal Window - twitter-bootstrap-3

I am using bootstrap 3. There is a select box inside the modal window. On change event of that select box i have to display its value at console. First time the value is correct but after that no value is shown on change event. Here is my code.
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true"></button>
<h4 class="modal-title">Class</h4>
</div>
<div class="modal-body">
<form>
<div class="form-group">
<select name='class' id='class'>
<option value='Class 1'>1</option>
<option value='Class 2'>2</option>
<option value='Class 3'>3</option>
<option value='Class 4'>4</option>
</select>
</div>
</form>
</div>
<script>
var class = $('#class');
class.on('change', function (e) {
console.log(this.value);
});
</script>
Can anyone help me out..where I am wrong.
Note: The code is working first time without any problem. But when I close the modal & open the modal again without page refresh then no value is shown at console. If page is refreshed then its working.

Here is the working fiddle for you.
Please avoid using reserved keyword as variable, class or id names.[https://jsfiddle.net/4s5mkbj8/2/]
$('#class').on('change', function (e) {
console.log(this.value);
});

Vue.js 3 and Modal with DaisyUI (Tailwind CSS)

I'm tinkering with DaisyUI within Vue.js 3 (porting an existing Vue+Bootstrap application to Tailwind CSS). I liked the idea that DaisyUI doesn't have JS wizardry going on behind the scenes, yet there seems to be some CSS voodoo magic that is doing things more complicated than they need to be (or at least this is my impression).
From the DaisyUI examples, here's the modal I'm trying to integrate:
<input type="checkbox" id="my-modal" class="modal-toggle"/>
<div class="modal">
<div class="modal-box">
<h3 class="font-bold text-lg">Congratulations random Internet user!</h3>
<p class="py-4">You've been selected for a chance to get one year of subscription to use Wikipedia for free!</p>
<div class="modal-action">
<label for="my-modal" class="btn">Yay!</label>
</div>
</div>
</div>
no javascript, yet the problem is that the modal will come and go according to some obscure logic under the hood that tests the value of the my-modal input checkbox at the top. That's not what I want. I want my modal to come and go based on my v-show="showModal" vue3 reactive logic!
Daisy doesn't seem to make that possible. Or at least not easily. What am I missing?
The modal is controller by the input field, so to open or close the modal just toggle the value of that input:
<template>
<!-- The button to open payment modal -->
<label class="btn" #click="openPaymentModal">open modal</label>
<!-- Put this part before </body> tag -->
<input type="checkbox" v-model="paymentModalInput" id="payment-modal" class="modal-toggle" />
<div class="modal modal-bottom sm:modal-middle">
<div class="modal-box">
<h3 class="font-bold text-lg">Congratulations random Internet user!</h3>
<p class="py-4">You've been selected for a chance to get one year of subscription to use Wikipedia for free!</p>
<div class="modal-action">
<label class="btn" #click="closePaymentModal">Yay!</label>
</div>
</div>
</div>
</template>
<script lang="ts" setup>
const paymentModalInput = ref()
const openPaymentModal = () => {
paymentModalInput.value = true
}
const closePaymentModal = () => {
paymentModalInput.value = false
}
</script>

Don't see div with v-if, regardless of the value in the data

I have problem with displaying component with v-if.
In one component i have <div v-if="seen">...</div>.
In another component I have <button v-on:click="seen = !seen">...</button>.
In "var vue = nev Vue({...})" file, in data: I have seen: true and this is not working.
I found "solution" which works: example
and I tried this "function version" of data in my code, but it doesn't work too :/
Here is my code:
Main File
var vue = new Vue({
el: '#app',
components: {
Navigation,
Home,
Footer,
Login
},
data: function () {
return {
seen: true
}
},
template: "<div><navigation></navigation><login></login><home></home><Footer></Footer></div>"
})
template that I can't see
<div v-if="seen" id="loginbox">
<form>
<input type="text" placeholder="login" class="input is-rounded"/>
<input type="password" placeholder="password" class="input is-rounded"/>
</form>
</div>
button template
<div class="navbar-menu">
<div class="navbar-start"></div>
<div class="navbar-end">
<p class="nav-item">
<a class="nav-link" v-on:click="seen = !seen">Login</a>
</p>
<p class="nav-item">
<a class="nav-link">Register</a>
</p>
</div>
</div>
I expect that when I click on button, "loginbox" template will be shown.
EDIT:
I did it in half way. I used props (used export default...) in in template that I cannot seen. It not work properly, becouse now I can change value of "seen" only with button which is in this template. I'd like change value of it by button which is in another template.
You should somehow share data between components.
You can do it many ways, but for this case i suggest to use event handling https://v2.vuejs.org/v2/guide/events.html#ad

Vue.js: Loading template (or div) when user clicks button?

So I currently have a template sitting in a ".vue" file like so:
<template>
<div id="dataAttachToMe"></div>
</template>
I don't want this to load, unless a user clicks a button, something like
<button #click="loadTheTemplateAbove">See Data</button>
I've tried using this example:https://v2.vuejs.org/v2/guide/conditional.html#Controlling-Reusable-Elements-with-key. But it says something like "Component template should contain exactly one root element" in the error message.
I need more than a show/hide here I think, something that can initiate the template dynamically.
<template>
<div id="data">
<button #click="loadTemplate">Load the template</button>
<div v-if="buttonClicked">
<div id="dataAttachedToThisDiv"></div>
</div>
</div>
</template>
The error you are getting, means that there is more than one root element inside <template></template> tag.
It is required in Vue.js (and other template based frameworks/libraries) to have only one root element.
This will NOT work:
<template>
<div id="dataAttachToMe"></div>
<button #click="loadTheTemplateAbove">See Data</button>
</template>
This will work:
<template>
<div id="someRootDiv">
<div id="dataAttachToMe">Some data</div>
<button #click="loadTheTemplateAbove">See Data</button>
</div>
</template>
Here is a code example (App.vue) of what you are trying to achieve:
Basic idea: we have to create a variable, that will be changed upon button click. We add v-if directive that depends on that variable and will handle element's visibility.
Welcome to StackOverflow. When you get the error Component template should contain exactly one root element it means that you can only have one root element in your template. You can fix that error by wrapping everything in a blank div like so
<template>
<div>
<template v-if="loginType === 'username'">
<label>Username</label>
<input placeholder="Enter your username">
</template>
<template v-else>
<label>Email</label>
<input placeholder="Enter your email address">
</template>
</div>
</template>
Please edit your post and place you <script> tag. Conditional Rendering requires a data field of a boolean that you can place in your if statement on your template
<template>
<div>
<div v-if="show">{{message}}</div>
<div v-if="#show">Not Showing when show is set to false</div>
<button v-on:click="show = true">Show</button>
</div>
</template>
<script>
module.exports {
data: function () {
message: 'Hello Vue!',
show: false
}
}
</script>

vue js navigate to url with question mark

my Vue js project login template click button it redirects to like this
http://localhost:8080/#/login to http://localhost:8080/?#/login
both Url show interface.
1st Url not set the local storage variable 'token'.
2nd Url is set the local storage variable 'token'.
how to solve it?
Login.vue
<template>
<div class="row col-sm-12">
<form>
<div class="form-group">
<label>Email address:</label>
<input type="email" class="form-control" v-model="email">
</div>
<div class="form-group">
<label>Password:</label>
<input type="password" class="form-control" v-model="password">
</div>
<div class="checkbox">
<label><input type="checkbox"> Remember me</label>
</div>
<button #click="login" type="submit" class="btn btn-success">Submit</button>
</form>
</div>
</template>
<script>
export default{
data(){
return{
email:'',
password:''
}
},
methods: {
login(){
var data = {
email:this.email,
password:this.password
}
this.$http.post("api/auth/login",data)
.then(response => {
this.$auth.setToken(response.body.token)
// console.log(response)
})
}
}
}
</script>
The form is getting submitted as the button you have provided in the form has type="submit" which is the default behaviour of a button present inside form even if you do not add the attribute type="button"
So replace the type submit to button o prevent form submission like this:
<button #click="login" type="button" class="btn btn-success">Submit</button>
I just faced the same issue, and the provided solution did not worked for me (Vue 2.5.17).
I had to add a modifier to the #click event to prevent the default behavior:
<button class="btn btn-primary" #click.prevent="login">Login</button>
Changing the button type to button, you disable default form behaviour, like pressing enter and release submit event.
Just add a modifier to the #submit or #reset event to prevent default behaviour:
<b-form #submit.prevent="onSubmit" #reset.prevent="onReset">
In order to keep the default behaviour of submitting the form using the "Enter" key on the keyboard as well, another solution is:
to keep the type = 'submit' on the button
handle the event parameter on the callback and process it with event.preventDefault(); like that:
login(event){
event.preventDefault()
var data = {
email:this.email,
password:this.password
}
...
}
Event.preventDefault() will prevent the default behaviour which is here to submit the form on the current url with the issue we are dealing with here.

How i Solve this error?
I believe your problem is that your blueimp gallery is initially hidden as it is in a Bootstrap Modal. As such, when you first initialize the gallery it can't find the gallery. I think all you need to do is wait for the Bootstrap modal to be shown and then initialize the gallery.
Bootstrap triggers an event that you can listen for for this very purpose - http://getbootstrap.com/javascript/#modals-events - You probably want the shown.bs.modal event.
You would use it something like this. (assuming jQuery is loaded)
$('#portfolioModal1').on('shown.bs.modal', function (e) {
blueimp.Gallery(
document.getElementById('links').getElementsByTagName('a'),
{
container: '#blueimp-gallery-carousel',
carousel: true,
}
);
})
Bear in mind this is untested code and may not 'just work'. But hopefully you get the idea. You also may want to do a test to see if you've already initialized the gallery, as it stands this would re-initialize it every time the shown.bs.modal event was fired.
