Question

httpclient not firing onload and readystateevents..

Hi Folks,
I'm building an app with extjs / jquery and trying to use the HTTPClient supplied by titanium.

The request executes and I can see the response text when I examine the object, but it does not fire the onload and onreadystatechange events..any ideas?

CODE

    var xhr = Titanium.Network.createHTTPClient();
    xhr.timeout = 1000000;    
    xhr.open("GET","http://www.cnn.com");


    xhr.onreadystatechange = function(){
        console.log("herer");
    } 
    xhr.onload = function() {
        try{
            console.log("herer1");
            alert(this.responseText);
        }catch(e){
            console.log("herer2");
            alert(e);
        }
    };


    xhr.send();

I'm assuming we're looking at Titanium Desktop here, in which case you might want to consider just using the jQuery or ExtJS ajax implementations. You may find them a little easier to work with.

Using the HTTP client, it looks like you might be running into some timing issues - try calling open after assigning the event handlers - I dropped this code into the sandbox and it worked:

<script>
var xhr = Titanium.Network.createHTTPClient();
    xhr.timeout = 1000000;  

    xhr.onreadystatechange = function(){
        alert("herer");
    } 
    xhr.onload = function() {
        try{
            alert(this.responseText);
        }catch(e){
            alert(e);
        }
    };

     xhr.open("GET","http://www.cnn.com");

    xhr.send();
</script>
