          NEW QUESTION 8
          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?

          • A. xhr.onCallback = xhrHandler;
          • B. xhr.onreadystatechange = xhrHandler;
          • C. xhr.readyState = xhrHandler;
          • D. xhr.status = xhrHandler;

          Answer: B

          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();

              You are developing an HTML5 page named main.html. The JavaScript code for the main page is located in a file named myApp.js.
              You need to create a web worker and instantiate it from main.html. Where should you place the web worker code?

              • A. In the myApp.js file
              • B. In the main.html file
              • C. In a separate .js (JavaScript) file
              • D. In a separate executable file

              Answer: C

              Explanation: Spawning a dedicated worker
              Creating a new worker is simple. All you need to do is call the Worker() constructor, specifying the URI of a script to execute in the worker thread (main.js):

              The inner paragraph must be exactly 15 pixels from the top left corner of the outer paragraph. You set the left style for the inner paragraph to the appropriate value.
              You need to set the position property of the inner paragraph. Which value should you use?

              • A. absolute
              • B. static
              • C. fixed
              • D. relative

              Answer: A

              Explanation: absolute: The element is positioned relative to its first positioned (not static) ancestor element. Incorrect:
              Not D:
              relative: The element is positioned relative to its normal position, so "left:20" adds 20 pixels to the element's LEFT position.

              NEW QUESTION 13
              DRAG DROP
              You create an HTML5 application that includes JavaScript. The application performs several AJAX requests. One AJAX request retrieves order information from a web service and then sends the information back to a webpage within the application.
              You must create a custom event. You have the following requirements:
              The webpage must contain an HTML element named ordersListing that will receive the custom event notification.
              The event name must be ordersReceived.
              The event must pass a custom value named orderCount.
              The event must run a JavaScript method named showOrdersReceivedCount after the orders Listing HTML element receives the event.
              Do not allow other DOM elements to receive the event. Allow the event to be cancelled.
              Send the event into the event system.
              You need to implement the custom event to notify specific DOM elements of the AJAX response. Which three actions should you perform in sequence? (Develop the solution by selecting the required code segments and arranging them in the correct order.)
              70-480 dumps exhibit

                Answer:

                Explanation: * From Scenario: Do not allow other DOM elements to receive the event. So: bubbles: false
                * From scenario: Allow the event to be cancelled. So: cancellable: true
                * From scenario:
                The webpage must contain an HTML element named ordersListing that will receive the custom event notification.
                * Events which are designated as bubbling will initially proceed with the same event flow as non- bubbling events. The event is dispatched to its target EventTarget and any event listeners found there are triggered. Bubbling events will then trigger any additional event listeners found by following the EventTarget's parent chain upward, checking for any event listeners registered on each successive EventTarget. This upward propagation will continue up to and including the Document. EventListeners registered as capturers will not be triggered during this phase. The chain of EventTargets from the event target to the top of the tree is determined before the initial dispatch of the event. If modifications occur to the tree during event processing, event flow will proceed based on the initial state of the tree.
                Note:
                * Ajax (an acronym for Asynchronous JavaScript and XML) is a group of interrelated web development techniques used on the client-side to create asynchronous web applications. With Ajax, web applications can send data to, and retrieve data from, a server asynchronously (in the background) without interfering with the display and behavior of the existing page. Data can be retrieved using the XMLHttpRequest object. Despite the name, the use of XML is not required (JSON is often used instead), and the requests do not need to be asynchronous.
