    Object Required In Ie After Xmlhttprequest

    in JavaScript

    Posted

    It could be saying that anything in the expression is undefined, not necessarily the XML object. Try alerting each thing to figure out which is not defined.alert(xmlDoc);alert(xmlDoc.getElementsByTagName("hometown"));alert(xmlDoc.getElementsByTagName("hometown")[0]);alert(xmlDoc.getElementsByTagName("hometown")[0].childNodes);alert(xmlDoc.getElementsByTagName("hometown")[0].childNodes[0]);alert(xmlDoc.getElementsByTagName("hometown")[0].childNodes[0].nodeValue);This line alone:xmlDoc=xmlhttp.responseXML;Is not going to set xmlDoc to an object, at that point it's just a string. You need to explicitly create a new object, I think the object you're looking for is a DOMDocument object but I could be wrong.
    in IE alert(xmlDoc); returns object alert(xmlDoc.getElementsByTagName("hometown")); returns object alert(xmlDoc.getElementsByTagName("hometown")[0]); returns null it doesnt matter which fireld i refer to note: 1. all other browsers work fine 2. this program is identical (i think) to the w3schools program PHP - AJAX responseXML
