How do you hide or get rid of debug and error messages that appears when you load a webpage???

Uh, fix the errors :D

Seriously...what exactly are you trying to do? Debug errors? Or cancel the notification of errors to the user?

window.onerror = function(){return true;}

or if you want to customize the error:

window.onerror=errorHandler;
function errorHandler(reason,page,line) {
alert('A JavaScript error has occurred on the page:\n '+page+'\n\nOn line #:\n '+line+'\n\nFor the reason:\n '+reason;
return true;//return true to suppress the error message thrown by the browser
}

Well, I know I made a joke about it in my first post, but it really is best to find the error and fix it. What are the details of the error? Is your page online so I can see it?

ok thats my source code
it says T is undefined line 125
but without it the code does not work
hey beetle this is like a code snippet aswell :)

Can you highlight line 125? I can't possibly know which it is, I could guess, but I would probably just be wasting time.

To remove the similies, edit the post, and check the checkbox that says 'Disable Smilies in This Post'

asian42die4,
I don't want to appear as if I'm picking on you, but most of your questions suffer from the following problems:

1) Gross lack of description/articulation of what the problem is
2) Dumping full page lengths of script, instead of doing some work yourself first, and posting only the problematic code.

This is why we created the Posting Guideline, which can be viewed here: http://www.codingforums.com/showthread.php?s=&threadid=2090

Sorry about that, sometimes I have lack of information, but I have done the work... but like heres the thing i under stand how it works but my knowledge of Javascript is minimal, but like if i use the VB i know, they do not declare it as a integer...

If the blue highligted line is the one you're always seeing the error on then it's obvious the problem is that the global variable t isn't being declared and is only given a value in other functions (which therefore declare it as a global variable by default). The code is checking the value of t before it's been given a value so it doesn't exist and thus gives the error. Declare the variable, give it a default value and the error should go away.
