Question

I have a form that when you submit it, it sends the data for validation to another php script via ajax. Validation errors are echo\'d back in a div in my form. A success messa

Answer 1

if(xmlhttp.readyState == 4 && xmlhttp.status == 200){

//Since your making php do the validation, there would be two cases,
//the first case is that the php script is not echoing any thing on success, and 
//the other case is that its echoing the error massages which will be assignedxmhttp.responseText
//so we need to check that xmlhttp.resposeText has been asigned a value.

   if(xmlhttp.resposeText){
       document.getElementById(displayContainers_id).innerHTML=xmlhttp.responseText;
   }
}
