Uncaught Error: Method show does not exist on jQuery.modal

Question

So I'm trying to force keep the bootstrap modal showing even on the toggle button click using $('#myModal').modal('show'); show method works when outside .click() function but says no such method when it is inside the .click() function

As such

$('document').ready(function() {

    $('#my-toggle-button').click(function() {   
        $('#myModal').modal('show'); // Throws up the below error
    });

});

Error:

Uncaught Error: Method show does not exist on jQuery.modal
at Function.error (jquery-2.2.4.min.js:2)
at n.fn.init.a.fn.modal (materialize.min.js:8)
at HTMLAnchorElement.<anonymous> (myScript.js:4)
at HTMLAnchorElement.dispatch (jquery-2.2.4.min.js:3)
at HTMLAnchorElement.r.handle (jquery-2.2.4.min.js:3)

However it works fine when

$('document').ready(function() {

    $('#myModal').modal('show'); // Works fine

    $('#my-toggle-button').click(function() {   

    });

});

Update: Turns out it's being caused because of script imports having defer and aysnc. I don't know what's the right place to use these as they don't recognize modal.

Answer 1

This problem occurs when trying to execute a bootstrap modal when you are also using materializecss, the best recommendation is to use the materializecss modal.

http://materializecss.com/modals.html

//initialize all modals
$('.modal').modal({
    dismissible: true
});

//call the specific div (modal)
$('#modal2').modal('open');

Enjoy!

Please, check the reference to bootstrap.js or bootstrap.min.js file. The file must include modals component. Also you need to check identificators of the modal and the button. The code must work fine, see the snippet below.

$('#my-toggle-button').click(function() {
  $('#myModal').modal('show');
});
