I am trying to show _FOC_NULL value when the edit box is blank. I put the below code on onclick button. it works when i click the button twice.
i appreciate your help, if i am missing anything in the below code.

 
//Begin function button1_onclick
function button1_onclick(event) {
var eventObject = event ? event : window.event;
var ctrl = eventObject.target ? eventObject.target : eventObject.srcElement;
var mystring = document.getElementById('edit1').value;
     if(!mystring.match(/\S/)) {
        document.getElementById('edit1').value = '_FOC_NULL' ;
        document.getElementById('combobox1').value = '_FOC_NULL' ;
          }
else {
 return true; }
}
//End function button1_onclick

I am a bit confused by this post, _FOC_NULL will never have a value hence the word NULL..
