[avinash]

I wanted to trim the varible for any leading and trailing empty spaces i.e if somebody enters a variable in the dynamic text box ,i should be able to remove the blank spaces in the beginng or the end.Is their any inbulit function in flash for triming?(like TRIM in ASP)If not how can i go about making this function i mean do i need to check each word...how?

Try this:

function trim(str) {
	var s=0;
	var e=str.length;
	while (str.charAt(s)==" ") {
		s++;
	}
	while (str.charAt(e-1)==" ") {
		e--;
	}
	return(str.substring(s,e));
}

trace("!" + trim("    THIS SHOULD WORK    ") + "!");
