New JavaScript Error

[cmattoon]

Hi all,

I recently put a live search box on a website, and it was working fine for the past few weeks. Suddenly, I receive the following error when the page is accessed via a link (after it's accessed, 'refresh' cures the problem) - but I'm not sure why it's showing up suddenly. The search box does not work when the error is shown.

 

Webpage error details

Message: Object doesn't support this property or method

Lines 1-9 of "ajax_search.js":

function getXmlHttpRequestObject() {
if (window.XMLHttpRequest) {
	return new XMLHttpRequest();	
} else if(window.ActiveXObject) {
	return new ActiveXObject("Microsoft.XMLHTTP");	
} else {
	alert("Your Browser Sucks!");	
}
}

 

I've tried deleting the whitespace and replacing it, in hopes that character 3 was an invalid 'invisible' character, but that didn't work. I also uploaded the backup copy, in case it was the other guy who messed it up (which I doubt, since neither of us touch JS files that are working...purely for this reason..)

 

Any thoughts?

 

Thanks!

You could use the IE8 developer tools te debug: press F12 -> script tab -> debugging option.

 

So apparently it trips over the XMLHttpRequest object? Try:

 

function createXMLHttpRequest() {
  var myXMLObject = false;
  if (window.XMLHttpRequest) {
   myXMLObject = new XMLHttpRequest();
  } else if(window.ActiveXObject) {
   try {
    myXMLObject = new ActiveXObject("Msxml2.XMLHTTP");
   } catch (e) {
    try {
     myXMLObject = new ActiveXObject("Microsoft.XMLHTTP");
    } catch (e) {
     myXMLObject = false;
    }
   }
  }
  return myXMLObject;
};
