Subject [jira] [Commented] (CB-5203) Using XmlHTTPRequest.open on WP8 raises a TypeError
Date Tue, 12 Nov 2013 11:21:19 GMT

    [ https://issues.apache.org/jira/browse/CB-5203?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13820023#comment-13820023
] 

Sergey Grebnov commented on CB-5203:
------------------------------------

With Weinre connected - I see exactly the same behavior, custom XHR logic is not called at
all, same js code called inside index.js file fails with the same error.
W/o Weinre - everything works as expected. Btw, when you do open you specify async = true
but handles xhr.responseText right after the send() call. So it must be corrected to
xhr.open('GET', 'js/index.js', false);
OR
var xhr = new XMLHttpRequest();
xhr.open('GET', 'js/index.js', true);
xhr.onreadystatechange = function() {
    if (xhr.readyState == 4) {
        console.log(xhr.responseText);
    }
}
xhr.send();

> Using the {{cordova-app-hello-world}} code on a WP8 device, connected to the device through
weinre, trying to use XMLHTTPRequest like this:
> {code:language=javascript}
> var xhr = new XMLHttpRequest();
> xhr.open('GET', 'js/index.js', true);
> xhr.send();
> console.log(xhr.responseText);
> {code}
> An error is raised at {{xhr.open}}: {{TypeError: Object doesn't support property or method
'addEventListener'}}
> The same code on iOS runs through and shows me the content of {{index.js}}.
> Changing the call to:
> {code:javascript}
> var xhr = new XMLHttpRequest();
> xhr._url = 'js/index.js';
> xhr.send();
> console.log(xhr.responseText);
> {code}
> Returns the expected result.
> I also noticed that {{XMLHttpRequest.prototype.open}} does not match the code in {{cordovalib\XHRHelper.cs}}:
> {code:title=XMLHttpRequest.prototype.open|javascript}
> function() {
> var result;
> callBeforeHooks(hookSite, this, arguments);
> try {
> result = func.apply(this, arguments);
> } catch (e) {
> callExceptHooks(hookSite, this, arguments, e);
> throw e;
> } finally {
> callAfterHooks(hookSite, this, arguments, result);
> }
> return result;
> }
> {code}
