[jQuery] Syntax confusion
X-no-archive:yes
Is the comma after line 1854 valid syntax or is it an error?
// Init the element's event structure
1854 var events = jQuery.data(elem, "events") || jQuery.data(elem,
"events", {}),
1855 handle = jQuery.data(elem, "handle") || jQuery.data(elem,
"handle", function(){
1856 // returned undefined or false
1857 var val;
1858
1859 // Handle the second event of a trigger and when
1860 // an event is called after a page has unloaded
1861 if ( typeof jQuery == "undefined" || jQuery.event.triggered )
1862 return val;
1863
1864 val = jQuery.event.handle.apply(arguments.callee.elem,
arguments);
1865
1866 return val;
1867 });
