Question

I have:

<div data-role="page" class="type-interior">
    <div data-role="content" class="ui-body">
        <a href="#transitionExample" data-role="button" data-rel="popup">
          Pop Up
        </a>
        <div data-role="popup" id="transitionExample">This is a POP UP.</div>
        <a href=# onClick="$('transitionExample').popup('open')"
        data-rel="popup">OpenPopUp</a>
    </div>
</div>

If I click on Button It Works, but if I use Javascript method .popup(‘open’), nothing happens. Popup is not showed.

What is happening?
I use, JqueryMobile 1.2.0 and JQuery 1.8.2.

Answer 1

$('transitionExample').popup('open')

should be

$('#transitionExample').popup('open')

for more info see: http://api.jquery.com/id-selector/

then you better bind your link in the .ready(), you should try to avoid Javascript code in the DOM for better maintainability.

 <a href='#' id='myButton' data-rel="popup">OpenPopUp</a>

and between your <script></script> tags

$(function () {
    $("#myButton").click(function () {
        $('#transitionExample').popup('open');
    });
});
