}

function gotoLogin invokes as follows

HTML

<input type="submit" name="Submit" value="Log in" onclick="gotoLogin(this.form)"/>

If anyone has any clue to correct this please let me know.
thanks.

On what grounds do you say readyState==4 is not set?

For all I can see, there are two conditions in your if condition.

Try following and see what's happening.

JavaScript

if (xmlHttp.readyState == 4) {
    alert('readyState==4, status==' + xmlHttp.status);

    if (xmlHttp.status == 200) {
        document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
    }
}

And see what happens.

Thank you very for your concern. I ckecked out your code fragment. But "alert" is not working

krumia 9-Jun-12 9:08am

What do you mean by alert not working?
Okay, does your function gets called at all?
Did you try to debug the code?
Did you try putting some alert() calls in the beginning of the getLogin function, and at the beginning of each if block? Are you trying to debug your code using us?
