Text Box Validation

[Mark Sreeves]

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

<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>
