Unable to retrieve responseText from AJAX call using XrayWrapper

Question

Unable to retrieve responseText from AJAX call using XrayWrapper

I am utilizing the IUI framework and attempting to retrieve the results from an ajax call.

When inspecting the call in Firebug, it shows an "XrayWrapper[Object XMLHttpRequest{}", but I am struggling to access the responseText from the object.

Upon expanding in Firebug, the responseText is displayed as an attribute, but it is prefixed in a lighter gray text with "get: 'getResponseText'".

var data = iui.ajax('login.php',{'userName':'sysadm','password':'sysadm'},'POST',null,xxxx(data))
console.log(data.responseText);

I have attempted various methods such as data.get.responseText, data.get('responseText'), etc., but still cannot retrieve the response.

Any insights on why this might be happening?

When making AJAX calls, it's important to remember that they are asynchronous. This means that the AJAX request is fired off and immediately logs the data to the console, even before the request has completed. To ensure that the callback function executes only after the asynchronous request is finished, you need to utilize a callback function.

After reviewing the IUI docs here, it appears that the fourth argument should be the callback function. Therefore, your code should look like this:

iui.ajax('login.php',{
        'userName':'sysadm',
        'password':'sysadm'
    },'POST', function(data) {
        // callback function. Only executes after ajax request completes
        console.log(data);
    }   
);

PS - Additionally, it seems that you have an extra argument. According to the documentation, there should only be four arguments: url, params, method, and callback.
