Script Syntax

oXMLDOMDocument.onreadystatechange = funcMyEventHandler;
objXMLDOMDocument.onreadystatechange = value;

Example

The following script example specifies the handler CheckState gets called when the readyState property changes.

<script>
var xmldoc;
function Load(){
   xmldoc = new ActiveXObject5.0("Msxml2.DOMDocument.5.0");
   xmldoc.onreadystatechange = CheckState;
   xmldoc.load(URL.value);
   if (xmlDoc.parseError.errorCode <> 0) {
      var myErr = xmlDoc.parseError;
      alert("You have error " + myErr.reason);
   }
}
function CheckState(){
  var state = xmldoc.readyState;
  RESULTS.innerHTML += "readyState = " + state + "<BR>"
  if (state == 4){
    var err = xmldoc.parseError;
    if (err.errorCode != 0)
      RESULTS.innerHTML += err.reason +  "<BR>"
    else RESULTS.innerHTML += "Success" +  "<BR>"
  } 
} 
</script>
URL: <input type=text size=60 id=URL><input type=button value=LOAD onclick=jscript:Load()>
<div id=RESULTS style="color:red; font-weight:bold;"></div></script> 

In Microsoft® Visual Basic® Scripting Edition (VBScript), you can get a function pointer using the syntax getRef("HandleStateChange").
