this not working in IE

cgishack · December 9th, 2006, 01:35 AM

Hello the below code is working in FF for me, but it IE its not.
[ill explain]

Code:

theReply = http.responseXML;
var layerInfo = theReply.getElementsByTagName("LAYERINFO");
alert(layerInfo.length);

FF is returning the proper length (27 characters) where IE returns 0 as a length

Any help would be great!

Firtst of all alert the http.responseText and, in IE, the http.responseXXML.xml, to make sure there actually is a response. Often IE doesn't recognise the content type of the response and so cannot form an XML document.
If this doesn't help let us know where in the book this example is taken from.

Hi,
Well from my readings it seems to be a Content-Type issue
The example i showed you above is not in the book. Its me just playing around and getting to know ajax more.

If I alert(http.responseXML.xml) in IE, i get nothing.
If I alert(http.responseText) in IE i do my get result.

How can it tell IE that the information coming in is in XML so it will work?
I do not have control of the XML coming in, it comes from a program I do not have access too.

Drew - you should set the content type of the response on the server-side.

For future reference, this forum is for supporting the book. General JavaScript/Ajax questions should be posted in the General JavaScript forum.

Thanks.

Thanks for the tip.
I am unable to set the content type on the server side because it comes from an external program i do not have control over.
I might look into converting it into an XML document somehow...

Ya. I googled "Ajax Forum" and this was in the top 3 results. I never really looked to see it was related to a book. :)

All good though. Gave me exposure to the site and maybe ill look into purchasing the book :)

Well in that case you need to hack it. If using IE load the responseText into a DomDocument and proceed from there.
You can also look at getAllResponseHeaders() to see what the actual content type is, it maybe one that IE doesn't recognise.
