| Question ID 14871 | You are developing a web page that consumes a Windows Communication Foundation
(WCF) service. The page includes the following code segment.
var xhr = new XMLHttpRequest() ;
The page uses the xhrHandler() method to listen for changes to the request status of the
WCF service calls. It uses the xmlToJavaScript() method to convert the response from the
WCF service to a JavaScript object.
The xhrHandler() method must be called automatically each time the request status
changes.
You need to add the event handler to the request object.
Which line of code should you use?
|
| Option A | xhr.onCallback = xhrHandler;
|
| Option B | xhr.onreadystatechange = xhrHandler;
|
| Option C | xhr.readyState = xhrHandler;
|
| Option D | xhr.status = xhrHandler;
|
| Correct Answer | B |
Explanation Explanation: / onreadystatechange: Sets or retrieves the event handler for asynchronous requests. Specifies a reference to an event handler for an event that fires at every state change readyState Returns the state of the object as follows: * 0 = uninitialized open() has not yet been called. * 1 = open send() has not yet been called. * 2 = sent send() has been called, headers and status are available. * 3 = receiving Downloading, responseText holds partial data (although this functionality is not available in IE [3]) * 4 = loaded Done. / Example (assuming that there is a function handler(): var oReq = getXMLHttpRequest(); if (oReq != null) { oReq.open("GET", "http://localhost/test.xml", true); oReq.onreadystatechange = handler; oReq.send(); Reference: XMLHttpRequest object; XMLHttpRequest (XHR) https://msdn.microsoft.com/en-us/library/ie/ms535874(v=vs.85).aspx http://mrfwebdesign.blogspot.ca/2008/11/xmlhttprequest-xhr.html
