hi all
in the following syntax document.getElementById('ID').innerHTML = 'value'; ID here is the element that has to be changed .is there any other way to use this method if the ID is not known.

What do you know? You must know something in order to find the right element. The right method depends on the situation-- you can use several other identifiers such as: location (first child element of a known element, for example), class (like id, but can be several elements), type (table, a, div, etc), maybe id based on some other knowledge you can determine?
