mb81 Posted May 17, 2006 Share Posted May 17, 2006 I am working on a simple AJAX function, but I seem to be having trouble with the http.open in the following code and I'm not sure what's going wrong. It may be something as simple as a bad a file reference, but I have used both relative and absolute links and neither has worked. I have verified that the http is an object. Any help would be appreciated.variablepassed:file: ./ajaxtoolbox/checkusername.phpargs: ?username=testsendtodivID= 'usernamechecktext'turnoffdivID = ''[code]function createRequestObject() { var ro; if (window.XMLHttpRequest) { ro = new XMLHttpRequest(); } else if (window.ActiveXObject) { ro = new ActiveXObject("Microsoft.XMLHTTP"); } else if (window.ActiveXObject) { ro = new ActiveXObject("Msxml2.XMLHTTP"); } else { ro = false; } return ro;}var http = createRequestObject();function specifyReq(file,args,sendtodivID,turnoffdivID) { if (http) { http.open('GET',file+args); } http.onreadystatechange = function() { if (http.readyState==4) { document.getElementById(sendtodivID).innerHTML = http.responseText; if (document.getElementById(turnoffdivID)) { document.getElementById(turnoffdivID).innerHTML = ""; } } };}[/code] Quote Link to comment https://forums.phpfreaks.com/topic/9866-problem-with-httpopen-related-to-ajax/ Share on other sites More sharing options...
