As a result document.getElementById("username") returns null and null.value throws an exception, since null is not allowed to have properties. Exactly why that is not finding your element depends on your HTML and when this JS snippets runs. share|improve this answer answered Feb 13 '12 at 5:37 Alex Wayne 86.3k27201249 add a comment| up vote 1 down vote try to put this text to debug alert(document.getElementById("use

The guy is making me crazy with this dumb thing and I am saying it has to be something on his machine because I see no problems, nor get any errors on any of my machines. Here is the code: function show_preview() { window.open("c_pop.php?to=" + document.getElementById('livesearch').value + "&sub=" + document.getElementById('subject').value object required + "&mess= " + document.getElementById('message').value, "Link", "toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1,resizable=1,width=450,height=400,left=30,top=80"); } The error from IE is simple: "Object required" line 2 character 2 - the window.open is line 2 Anyone able to help me get this guy out of my hair cause I give up!

UGH crmalibu 2009-06-03 17:53:12 UTC #5 Break your code up into many lines so the line number in the error message is more specific. Instead of assuming an object has a property or method, test it before using it. if (window.open) { window.open(...); } var elem = document.getElementById('livesearch'); // elem could be null. trying to use a property of something that is null will throw an error if (elem) { // elem is not null, we can use the property elem.value; } Be aware that an element with the given id needs to exist at the time that script runs for getElementById() to be able to grab it. dc_dalton 2009-06-03 18:20:42 UTC #6 crmalibu said: Break your code up into many lines so the line number i
