This has been driving me insane so hopefully someone can help me out :-D

I am trying to create a jquery mobile popup and within the popup I want to dynamically create a jQuery mobile listview. However I keep getting the following error message.

Uncaught TypeError: Cannot read property 'jQuery19104145257784985006' of undefined.

Here is my code

$('#create').on('click', function () {
    //create a div for the popup
    var $popUp = $("<div/>").popup({
        dismissible: false,
        theme: "a",
        overlyaTheme: "a",
        transition: "pop"
    }).on("popupafterclose", function () {
        //remove the popup when closing
        $(this).remove();
    });

    //create a title for the popup
    $("<ul data-role='listview'/>").trigger("create").appendTo($popUp);

    $popUp.popup('open').trigger("create");
});

I have created a basic jsFiddle here http://jsfiddle.net/QA7Dm/

Any help is gratefully appreciated.

  • Remove `trigger('create')` after appending listview, underneath it add `$('[data-role=listview]').trigger('refresh');` – Omar May 07 '13 at 20:42

JS :

$(document).on('pageshow', '#index', function(){ 
    $(document).on('click', '#create', function(){     
        $('<div>').attr({'data-role':'popup','id':'popupBasic','data-dismissible':'false','data-theme':'a','data-transition':'pop'}).appendTo('[data-role="content"]');
        $('<div>').attr({'data-role':'header','data-theme':'b','id':'popup-header'}).append('<h1>Header</h1>').appendTo('#popupBasic');
        $('<ul>').attr({'data-role':'listview','id':'list-test','data-theme':'a'}).appendTo('#popupBasic');
        $('<li>').append('List test').appendTo('#list-test');
        $('#index').trigger('pagecreate');
        var popup = setInterval(function(){
            $("#popupBasic").popup("open",{
                overlyaTheme: "a"
            }).on("popupafterclose", function () {
                //remove the popup when closing
                $(this).remove();
            });
            clearInterval(popup);
        },1);      
    });    
});

  • Thanks for the in depth answer. I have simplified it a little but your answer has given me a good understanding. Thanks – user1812741 May 07 '13 at 21:34

Here is the fix.

$('#create').on('click', function () {
var $popUp = $("<div/>").popup({
    dismissible: false,
    theme: "a",
    overlyaTheme: "a",
    transition: "pop"
 }).on("popupafterclose", function () {
    $(this).remove();
 });
 $("<ul id='test' data-role='listview'/>").trigger("refresh").appendTo($popUp);
$popUp.popup('open');
});
