OnReadyStateChange

Aug 26, 2005

So, my boss is obessed with AJAX and is convinced we need to use it for all of our js menus. I've unfortunately run into some issues with the code below.

It's not throwing any errors in IE or FireFox, but it's not working. IE never shows the 'handler' alert, and FireFox shows the 'handler' alert 3 times, but doesn't seem to ever get to readyState 4 to display the 'loaded' alert. Code:

Onreadystatechange Event Not Firing With XMLHttpRequest

Oct 11, 2010

It seems there's something wrong with my AJAX code. The onreadystatechange event does not fire. Here is my code:

function fetchPage() {
href = "examples/css1/e.html";
var client = new XMLHttpRequest();
client.onreadystatechange = function () {

[Code].....

So with this code, the "onreadystatechange" alert never pops up.

Sending Arguments To Xmlhttp.onreadystatechange Event

Oct 28, 2005

Hw do I send arguments to an onreadystatefunction when calling a document via xmlhttprequest object. For example,

I want to do something like

function getDoc(url)
xmlhttp=new XMLHttpRequest();
xmlhttp.onreadystatechange=writeHTML(id);
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}

function writeHTML(id){
if (xmlhttp.readyState==4)
{
// if "OK"
if (xmlhttp.status==200)
{
document.getElementById(id).innerHTML = xmlhttp.responseText;
}
}

OnReadyStateChange Firing In Safari And Opera But Not In Firefox?

Dec 22, 2010

I have a simple XHR request that works well in Safari and Opera but not in Firefox. I have the following code:

Code JavaScript:
function AJAX(ajaxurl, ajaxdata, ajaxcallback){
if(!ajaxcallback) ajaxcallback=function(){};
var ajaxreqobj = new XMLHttpRequest();

[Code].....

Making Firefox 3 use the standard "ajaxreqobj.send(ajaxpostdata);" does not fix the problem.

What in the world is making my simple AJAX request work in Safari and Opera but not in Firefox?

Onreadystatechange Expecting - Pass An Argument To A Function To Process Server Responses

May 10, 2011

I am trying to pass an argument to a function to process server responses. My original line of code looked like this: [url]

This works well enough as is, but I am trying to pass arguments to the function, and everything I am reading says to contruct the code like this: [url]

Every example I have come across uses this same approach, but I keep getting the error "Expected ';'" pointing to this line and then the code fails to execute. I just cannot see where there is anything missing, and it looks pretty much identical to my examples.

I have also tried replacing the call to the function with the actual code in long-form, and the result is the same.
