Javascript-Trim functions

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....

Code:

---

<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 ?

Code:

---

<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!

Code:

---


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

This is correct and it works fine for me.
