Javascript-Trim functions

[ranjith]

Can any one tell me,what are the equivalent functions in Javascript for trim,rtrim ,and ltrim.

There's no JavaScript trim() function as such. This should suit your needs though....

<script language="JavaScript">
<!-- 
function trim(strText) {
    	// this will get rid of leading spaces
    	while (strText.substring(0,1) == ' ')
        	strText = strText.substring(1, strText.length);     
	
	// this will get rid of trailing spaces
    	while (strText.substring(strText.length-1,strText.length) == ' ')
        	strText = strText.substring(0, strText.length-1);
    return strText;
}
 //--></script>

The script came from here: http://developer.irt.org/script/1310.htm

Hi, using the above trim function why is this not working ?

<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">
	
    function ValidateForm(form)
    {	
         //This line works
         alert ('*' + form.txtCourriel.value);

         // This line does not work 
         alert ('*' + trim(form.txtCourriel.value));
         // This line does not work 
         alert ('*' + trim(form.txtCourriel));
    } 
			
   </SCRIPT>

How do I use that trim function ?

Jeeze that's an old thread!

alert ('*' + trim(form.txtCourriel.value));

This is correct and it works fine for me.
