Text Box Validation

This will trim the leading and trailing spaces. You can then check the length != 0

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>
