为什么 jquery 不确认模态在我的应用程序上工作？

Question

can someone please tell me why is the jquery confirm modal doesn't work on my app? here's my code

        <div id="dialog-confirm" title="Empty the recycle bin?">
            <p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>These items will be permanently deleted and cannot be recovered. Are you sure?</p>
        </div>

here's the js code

 if(userid == ""){
        $( "#dialog:ui-dialog" ).dialog( "destroy" );

        $( "#dialog-confirm" ).dialog({
            resizable: false,
            height:140,
            modal: true,
            buttons: {
                "Delete all items": function() {
                    $( this ).dialog( "close" );
                },
                Cancel: function() {
                    $( this ).dialog( "close" );
                }
            }
        });
 }

there's no pop-up that come out, but when i tried the simple modal alert, it works

i have this in my header

jquery-ui.min.js
