javascript – TypeError: $(…).modal is not a function with bootstrap Modal-ThrowExceptions

Exception or error:

I have a bootstrap 2.32 modal which I am trying to dynamically insert into the HTML of another view. I’m working with Codeigniter 2.1. Following Dynamically inserting a bootstrap modal partial view into a view, I have:

<div id="modal_target"></div>

as the target div for insertion. I have a button in my view that looks like:

     <a href="#message" class="btn btn-large btn-info" data-action="Message" data-toggle="tab">Message</a>

My JS has:

$.ajax({
    type    : 'POST', 
    url     : "AjaxUpdate/get_modal",
    cache   : false,
    success : function(data){ 
       if(data){
            $('#modal_target').html(data);

            //This shows the modal
            $('#form-content').modal();
       }
    }
});

The button of the main view is:

<div id="thanks"><p><a data-toggle="modal" href="#form-content" class="btn btn-primary btn-large">Modal powers, activate!</a></p></div>

Here is what I’d like to store separately as a partial view:

<div id="form-content" class="modal hide fade in" style="display: none;">
    <div class="modal-header">
        <a class="close" data-dismiss="modal">×</a>
        <h3>Send me a message</h3>
    </div>
    <div class="modal-body">
        <form class="contact" name="contact">
             <fieldset>

               <!-- Form Name -->

            <legend>modalForm</legend>

            <!-- Text input-->
            <div class="control-group">
              <label class="control-label" for="user">User</label>
              <div class="controls">
                <input id="user" name="user" type="text" placeholder="User" class="input-xlarge" required="">
                <p class="help-block">help</p>
              </div>
            </div>

            <!-- Text input-->
            <div class="control-group">
              <label class="control-label" for="old">Old password</label>
              <div class="controls">
                <input id="old" name="old" type="text" placeholder="placeholder" class="input-xlarge">
                <p class="help-block">help</p>
              </div>
            </div>

            <!-- Text input-->
            <div class="control-group">
              <label class="control-label" for="new">New password</label>
              <div class="controls">
                <input id="new" name="new" type="text" placeholder="placeholder" class="input-xlarge">
                <p class="help-block">help</p>
              </div>
            </div>

            <!-- Text input-->
            <div class="control-group">
              <label class="control-label" for="repeat">Repeat new password</label>
              <div class="controls">
                <input id="repeat" name="repeat" type="text" placeholder="placeholder" class="input-xlarge">
                <p class="help-block">help</p>
              </div>
            </div>



                </fieldset>
        </form>
    </div>


    <div class="modal-footer">
        <input class="btn btn-success" type="submit" value="Send!" id="submit">
        <a href="#" class="btn" data-dismiss="modal">Nah.</a>
    </div>
</div>

When I click the button, the modal is inserted correctly, but I get the following error:

TypeError: $(...).modal is not a function 

How can I fix this?

How to solve:

i just want to emphasize what mwebber said in the comment:

also check if jQuery is not included twice

🙂

it was the issue for me

###

This error is actually the result of you not including bootstrap’s javascript before calling the modal function. Modal is defined in bootstrap.js not jQuery. It’s also important to note that bootstrap actually needs jQuery to define the modal function, so it’s vital that you include jQuery before including bootstrap’s javascript. To avoid the error just be sure to include jQuery then bootstrap’s javascript before you call the modal function. I usually do the following in my header tag:

<header>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
    <script src="/path/to/bootstrap/js/bootstrap.min.js"></script>
</header>

###

After linking up your jquery and bootstrap write your code just below the Script tags of jquery and bootstrap.

$(document).ready(function($) {
  $("#div").on("click", "a", function(event) {
    event.preventDefault();
    jQuery.noConflict();
    $('#myModal').modal('show');

  });
});
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>

<!-- Latest compiled JavaScript -->
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

###

Check that jquery library not included in html that load via Ajax .remove <script src="~/Scripts/jquery[ver].js"></script> in your AjaxUpdate/get_modal

###

Another possibility is that one of the other scripts your including is causing the problem by also including JQuery or conflicting with $. Try removing your other included scripts and see if it fixes the issue. In my case, after hours of needlessly searching my one code, I removed scripts in a binary search pattern and discovered the offending script right away.

###

I have resolved this issue in react by using it like this.

window.$('#modal-id').modal();

###

I resolved this issue in Laravel by modifing the line below in resources\assets\js\bootstrap.js

window.$ = window.jQuery = require('jquery/dist/jquery.slim');

to

window.$ = window.jQuery = require('jquery/dist/jquery');

###

Run

npm i @types/jquery
npm install -D @types/bootstrap

in the project to add the jquery types in your Angular Project.
After that include

import * as $ from "jquery";
import * as bootstrap from "bootstrap";

in your app.module.ts

Add

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

in your index.html just before the body closing tag.

And if you are running Angular 2-7 include “jquery” in the types field of tsconfig.app.json file.

This will remove all error of ‘modal’ and ‘$’ in your Angular project.

###

In my case, I use rails framework and require jQuery twice. I think that is a possible reason.

You can first check app/assets/application.js file. If the jquery and bootstrap-sprockets appears, then there is not need for a second library require. The file should be similar to this:

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap-sprockets
//= require_tree .

Then check app/views/layouts/application.html.erb, and remove the script for requiring jquery. For example:

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>

I think sometimes when newbies use multiple tutorial code examples will cause this issue.

###

In my experience, most probably its happened with jquery version(using multiple version) conflicts, for sort out the issue we can use a no-conflict method like below.

jQuery.noConflict();
(function( $ ) {
  $(function() {
    // More code using $ as alias to jQuery
    $('button').click(function(){
        $('#modalID').modal('show');
    });
  });
})(jQuery);

###

I had the same issue.
Changing

$.ajax(...)

to

jQuery.ajax(...)

did not work. But then I found that jQuery was included twice and removing one of them fixed the problem.

###

For me, I had //= require jquery after //= require bootstrap. Once I moved jquery before bootstrap, everything worked.

###

Other answers din’t work for me in my react.js application, so I have used plain JavaScript for this.

Below solution worked:

  1. Give an id for close part of the modal/dialog (“myModalClose” in below example)
<span>
   className="close cursor-pointer"
   data-dismiss="modal"
   aria-label="Close"
                     id="myModalClose"
>
...
  1. Generate a click event to the above close button, using that id:
   document.getElementById("myModalClose").click();

Possibly you could generate same click on close button, using jQuery too.

Hope that helps.

###

I guess you should use in your button

<a data-toggle="modal" href="#form-content"    

instead of href there should be data-target

<a data-toggle="modal" data-target="#form-content"    

just be sure, that modal content is already loaded

I think problem is, that showing modal is called twice, one in ajax call, that works fine, you said modal is shown correctly, but error probably comes with init action on that button, that should handle modal, this action cant be executed, because modal is not loaded at that time.
