TypeError: $(...).modal is not a function with bootstrap Modal

Solution 1:

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

Solution 2:

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>

Solution 3:

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>
