I am having some problems with that bit of code. Basically I am launching a popup window and this is my js file -
$('a[rel="email_page"]').click(function(){ window.open(this.href,'mywindow','height=580,width=400,scrollTo,resizable=0,scrollbars=0,location=0','false'); return false; }); // This passes along the URL of the parent opener when clicking "Email this page" $("#message").get(0).value += window.opener.location.href; but it seems to be causing a conflict in the rest of my code. My Firebug console log says - $("#message").get(0) is undefined If I comment out the line, everything works nicely. Any idea if I can get rid of this error and still retain the functionality?
