Thierry Posted July 2, 2007 Share Posted July 2, 2007 I'm getting my hand at AJAX and I've got a small problem. I'm simply using AJAX to test a request to the contents from an XML document and in Firefox it works perfectly, but in IE the contents never update, but they do in Firefox. As I'm new with AJAX its probably a small issue but I can't seem to find it. <html> <head> <title>AJAX test</title> <script language="javascript"> <!-- function data_request(url) { var httpRequest = ""; if(!(window.XMLHttpRequest == null)){ // Mozilla, Safari, ... httpRequest = new XMLHttpRequest(); //if we dont have a Content Type (format), we make it XML if(!(httpRequest.overrideMimeType == null)){ httpRequest.overrideMimeType('text/xml');} //attempt 1 for IE }else if(!(window.ActiveXObject == null)) { // IE try{ httpRequest = new ActiveXObject("Msxml2.XMLHTTP"); httpRequest.setHeader("Cache-Control", "no-cache");} //attempt 2 for IE catch(e){ try{httpRequest = new ActiveXObject("Microsoft.XMLHTTP"); httpRequest.setHeader("Cache-Control", "no-cache");} catch(e){}} } //end of if else //if we can't create the XML request, we end if(!httpRequest){ alert('Giving up Cannot create an XMLHTTP instance'); return false;} //ok, now we are gonna do our thing and then send the request httpRequest.onreadystatechange = function(){alertContents(httpRequest);} httpRequest.open('GET', url, true); httpRequest.send(''); //and our thing function alertContents(httpRequest) { //ready state values: // 0 (uninitialized) // 1 (loading) // 2 (loaded) // 3 (interactive) // 4 (complete) if(httpRequest.readyState == 4){ //status code of the HTTP server response, 200 is ok to go if (httpRequest.status == 200){ var xmldoc = httpRequest.responseXML; var root_node = xmldoc.getElementsByTagName('root').item(0); alert(root_node.firstChild.data);}else{ alert('There was a problem with the request.');}} } //end of alertContents } //end of data_request --> </script> </head> <input type="button" name="test" id="test" value="Test" onclick="data_request('testing.xml')"> <body> </body> </html> Any hint of what I'm doing wrong? (it works fine in Firefox 2.0) Link to comment https://forums.phpfreaks.com/topic/58087-new-at-ajax-ie/ Share on other sites More sharing options...
