How to use a button to show the modal in other components? For example, I have the following components:
info.vue
<template>
<div class="container">
<button class="btn btn-info" #click="showModal">show modal</button>
<example-modal></example-modal>
</div>
</template>
<script>
import exampleModal from './exampleModal.vue'
export default {
methods: {
showModal () {
// how to show the modal
}
},
components:{
"example-modal":exampleModal
}
}
</script>
exampleModal.vue
<template>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
hihi
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</template>
How to show the modal from exampleModal.vue? I know that I can
use data-toggle and data-target to show the modal, like this:
<button class="btn btn-info" data-toggle="modal" data-target="#exampleModal">show modal</button>
But is there any way to show the modal by using the method "showModal"?
According to your snippet, you're using a classic Bootstrap modal. You just need to use data-toggle and data-target attributes in that case:
<div id="app">
<div class="container">
<button class="btn btn-info" data-toggle="modal" data-target="#exampleModal">show modal</button>
<example-modal></example-modal>
</div>
</div>
Edit
I misread the question so i edit my answer.
It's possible to open the modal with a custom method. You just need to find the element "#exampleModal" by using refs and then open the modal with a bootstrap method (Bootstrap Programmatic API)
<div id="app">
<div class="container">
<button class="btn btn-info" #click="showModal">show modal</button>
<example-modal ref="modal"></example-modal>
</div>
</div>
methods: {
showModal() {
let element = this.$refs.modal.$el
$(element).modal('show')
}
}
Fiddle example
Without jQuery you could create a function on "method:" block like this:
openEditModal(data){
// <handle with your data>
this.$root.$emit("bv::show::modal", "your-modal-id");
}

From Bootstrap website, it always use button to show the modal.
I am using React, so I want to use javascript manipulate whether the modal shows.
Is there any way to make the modal show as default?
Modal.js
...
return(
<div class="modal" tabindex="-1" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>Modal body text goes here.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
)
import "./styles.css";
import Modal from './Model'
export default function App() {
return (
<div className="App">
<h1>123</h1>
<Modal/>
</div>
);
}
you can use jquery to show or hide
$("#id of your modal").modal("show");
$("#id of your modal").modal("hide");
jQuery must be referenced first . before the bootstrap
if you wanna use pure javascript only you can change it manually like bellow:
<!-- Modal -->
<div id="mymodal">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
<button type="button" class="close" id="close-btn" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button id="close-btn" type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
<script>
// select close buttons
const mymodal = document.getElementById('mymodal');
const close_btn = document.querySelectorAll("#close-btn");
//show the modal
mymodal.style.display = "block"
//close modal function
function hide() {
mymodal.style.display = "none"
}
//clise the modal when you click the close btns
close_btn.forEach(close => {
close.addEventListener("click", hide)
})
</script>
and change the script in order you want
I'm new to programming, and I have this simple question but I can't figure out how to do it.
I got this working code from Boostrap 4:
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalLong">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModalLong" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
But instead of having a button I want to create a function to fire up the modal content:
function openModal(){
/* DESCRIPTION: Open the warning modal */
// data-toggle="modal" data-target="#exampleModal"
}
But I don't know how to the same thing as data-toggle and
data-target do in the button click.
Someone has a hint how to do that?
You have to use the Bootstrap JS api for the modal ( Link attached at the end of this answer ).
Here is the straight answer :-)
function openModal(){
/* DESCRIPTION: Open the warning modal */
$('#exampleModalLong').modal('show');
}
Here is another SO question related to this : How can I trigger a Bootstrap modal programmatically?
Here is a detailed link on Bootstrap official documentation on various javascript methods for modals.
https://getbootstrap.com/docs/4.0/components/modal/#methods
Just use this line in your function:
$('#myModal').modal('show');
Note: remember to replace your modal id with myModal.
Below is the current HTML code --
<div class="container">
<h2>Basic Modal Example</h2>
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal 1</button>
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal 2</button>
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal 3</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Content of modal -- </p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
Here multiple buttons call the same modal. Now inside the modal there is no way to determine which button press has called this.
I want to modify the above code so that i can pass a parameter into the modal. For example, clicking on 1st button should pass "button 1" and that should be displayed in the modal body section.
I know I can add ng-click to the buttons and call a function. I can pass the string button 1/2/3 as its parameter. Inside the function I can set a particular global parameter value as the string passed. But how do I invoke the modal from inside this function? I am not sure whether this is even possible.
Please let me know how I can achieve the above using angular JS.
You can implement ng-clicks of each button and then can create a scope variable inside the function that gets triggered on click. And by using the same variable you can now update the modal body section.
HTML Would be like:
<div class="container">
<h2>Basic Modal Example</h2>
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal" ng-click="data = 'content 1'">Open Modal 1</button>
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal" ng-click="data = 'content 2'">Open Modal 2</button>
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal" ng-click="data = 'content 3'">Open Modal 3</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Content of modal -- {{data}} </p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
You don't need to use global things.
You can do it using resolve property.
defined the function which will going to call your modal function which open the modal.
<button ng-click="callModalFun('Btn1')">Btn1</button>
<button ng-click="callModalFun('Btn2')">Btn2</button>
<button ng-click="callModalFun('Btn3')">Btn3</button>
JS :
function callModalFun(strBtnName){
var modalInstance = modal.open({
..,
resolve : {
data : {
strFromBtn : strBtnName;
}
},
controller : 'myCtrl'
});
}
and in the controller do like this one.
.controller('myCtrl',function($scope,resolveData){
$scope.strBtnName = resolveData.data.strFromBtn;
})
strBtnName is available inside of the template.
I have 5 modal forms in a page. And I want to get the Id of the currently opened one.
I know I can check with $('#myModal').hasClass('in');. If I have 5 modal forms I have to write this 5 times. Which I don't want to.
Is there some way I can determine which modal the user has open currently open and then I will get the id of that.
You can use the shown.bs.modal event to get the current open modal.
Modal Events
shown.bs.modal
This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the relatedTarget property of the event.
Here is an example
$('.modal').on('shown.bs.modal', function (e) {
var crntModalId = "current modal id is: " + $(this).attr('id');
$('.output').text('');
$('.output').text(crntModalId);
})

It's very simple, with bootstrap modal event's
To get any attribute value from the modal trigger button you can use $(e.relatedTarget)
To get the modal attribute value you can use $(e.currentTarget)
In your case, you can get the Opened modal id with
$('.modal').on('shown.bs.modal', function(e) {
var modalid = $(e.currentTarget).attr('id');
});
Fiddle
A bootstrap modal gets automatically the class 'shown.bs.modal' when is open, so you can use this to track which one is open.
I have a bootstrap modal, which has table with attribute contenteditable = trueinside of it (table is created dynamically with js). I'd like to set up a neat feature - if user presses cancel then the changes in table will be dismissed. I understand that i could do this with writing a function for different states and then calling out the previous state in case of cancel. I'm just thinking that is there a quicker-better-faster approach?
I did some searching and found one link which had similar issue, but the approach and result there are a bit different from mine which means that it didn't work for me.
Here's my code - parts of it are in Estonian, i don't think in general code is necessary for this question but i'll still provide:
<div class="modal fade" id="ajamasinModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel"><i class="fa fa-cog" style="font-size:20px"></i> Ajamasin</h4>
</div>
<div class="modal-body">
<div id="changeablevoor"></div>
<button type="button" class="btn btn-primary" onClick="muudaClick()">Change</button>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-success" data-dismiss="modal">Save</button>
</div>
</div>
</div>
</div>
Try the following approach ( view comments inline ):
Html
<div class="modal fade" id="ajamasinModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
//...
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-success" data-dismiss="modal">Save</button>
</div>
</div>
</div>
</div>
JS
// Add hidden event of the modal
$('#ajamasinModal').on('hidden.bs.modal', function (e) {
cancelModal(); // Call the function to cancel the modal after hiding of the modal
})
// Cancel the modal
function cancelModal() {
// Re-generate content with default values
}
