I'm trying to drag a dialog in a web app and its not working why?
My code is something like this... draggable is set to true but still its not dragging... and for your info there is movable objects in the background also. dragging symbol is shown but the dialog is not moving why? Can you explain how to make a dialog draggable?
$dlgLibrary = $('<div style="overflow-y:hidden;color:#FBFBEF"" id="eBLibrary"></div>')
.dialog({
autoOpen: false,
title: 'Browse & Select',
maxWidth:1000,
maxHeight: 600,
width: 800,
height: 600,
dialogClass: "alertDialog",
modal: true,
closeOnEscape: true,
canMaximize:true,
draggable: true,
resizeHt: 0,
resizeWd: 0,
resizeStop: function(event, ui) {
if (resizeHt== 0 && resizeWd== 0) {
resizeHt = $dlgLibrary.dialog( "option", "height" );
resizeWd = $dlgLibrary.dialog( "option", "width" );
};
$('#eBLibrary-Show').width(Number(resizeWd-(resizeWd*16/100)));$('#eBLibrary-Show').height(Number(resizeHt-(resizeHt*35/100)));
resizeHt= 0;
resizeWd= 0;
},
open: function(event, ui) {
}
$.ajax({ url: './Library.html',
success : function(data) {
},
buttons: libButtons,
close: function() {
});
