I have a doubt regarding including tags in a function.
I have written a function in javascript in a html page. The
function got called by clicking a button, i want to display
the results in same html page by placing tags in the
function. (this hmtl page is static page)
Is this possible?
example:
<SCRIPT LANGUAGE=javascript>
function calSubmit_onclick() {
var xyz=0;
..........
..........
document.write("<lable>"+xyz+"</label>"); /*Is it
possible*/
}
