TypeError: $(...).modal is Not a Function with Bootstrap Modal

Issue

When dynamically inserting a Bootstrap modal into the HTML of another view, you may encounter the following error: TypeError: $(...).modal is not a function. This error indicates that the modal() method is not recognized by jQuery, preventing the modal from functioning properly.

Solution: Check jQuery Inclusion

To resolve this issue, first verify that jQuery is included in the project. Ensure that there are no duplicate inclusions of jQuery, as this can lead to conflicts. Confirm that the jQuery library is referenced and loaded after any other JavaScript libraries in the page's

Sample Implementation

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

            // Check if jQuery.modal is defined before calling it
            if ($.fn.modal && typeof $.fn.modal === 'function') {
                $('#form-content').modal();
            }
        }
    }
});
//...

Closing Remarks

By verifying the proper inclusion of jQuery and conditional execution of the modal() method based on its availability, you can ensure that your Bootstrap modal will function correctly and avoid the TypeError: $(...).modal is not a function error.
