javascript - Check if element exists -

-

possible duplicates:
is there “exists” function jquery
jquery determining if element exists on page

if(tr) returning true when tr not element, how check whether it's element exists?

var tr = $('#parts-table .no-data').parent(); $('.delete', row).bind('click', function (e) {   that.delete(e.currenttarget); }); console.log(tr); if (tr) //returns true when shouldn't

check length property:

if(tr.length) {     // exists }

if(tr) evaluates true because jquery object, or any javascript object matter, truthy.
