I call an ajax method which return a response that will be used to update the page via javascript.
This method gets bound to an onload event, and then calls itself every 30 seconds.
If the internet connection goes down, it shows me javascript error as show in below image file.

Did you try adding a custom error handling and detecting that error, canceling your interval if its hit?

Hello

I haven't written any custom error handling script.
Do You mean that I should not call that function again if the internet connection is down?
I have big Demo on weekend. Please help me in this.
script is as below.
It calls getUpdate() every 5 seconds.
Please tell me what I should do.
getUpdate()
{
strMessage = objLocal.getMessage();
if(strMessage)
{
/*
Parsing Script for strMessage
*/
}
setTimeout("getUpdate();",5000)
}

Correct its up too you to manage error conditions, HTML_AJAX doesn't do it for you automatically.

If you set
HTML_AJAX.onError(error,request) {
// an error happened, display error messages cancel future requests etc
}

You should be able to handle it. If the error isn't being caught if you can give me reproducable steps i'll try to get that part fixed, but depending on the cause (which IE bug) that could take awhile

Did adding an error handler work for you?
