Hello friends,

Sometimes we need to set the maxlength for textbox or textarea depend upon the value selected.

For example in US the zip code contain only 5 characters.But in india this going to be six.
It is simple and easiest way in the javascript.Set the maximum length by using the following code...

  
document.getelementid('textbox1").maxLength=10
