The principle behind the forward-caching Ajax client is very straightforward. You keep track of the ID of the current image and provide buttons that allow you to add and remove 1 from this ID. You then construct a URL to the image server, passing it the new ID and getting the response. Then you download the images that are 1 and 2 more than this value, as well as those that are 1 and 2 less than this value. When you call the URL and download the images, the browser will cache them. For example, if the current image is 100, and you move forward to 101, the page will construct a URL call to the server asking for 101. If this has already been called, the results will be cached, and the image loaded from the cache. It will also construct calls to 102, 103, 100, and 99, and put the responses in the browser cache. To do this, you need to use a slightly different technique from what you did in the simple example. You ll use two XMLHttpRequest objects: one with a callback that renders the image, and one that doesn t use a callback, but just gets the image and caches it. Add a new HTML page to your application and call it AJAXPictureClient.htm. Change the body of the application to contain a <div> in which the image will be displayed, and two buttons one for moving forward and one for moving backward. Here s the complete markup, including the JavaScript event-handler function calls that handle loading the page and clicking the buttons: java upc-a Generate UPC-A barcode in Java class using Java UPC-A ...

The configuration for the default implementation is: <barcode> < upc-a > <height>{ length:15mm}</height> <module-width>{length:0.33mm}</module-width> ... method accepts the complete XML markup fragment for the new node and appends it to the current node. However, the one that we used is more flexible. JavaServer Pages can use the portlet tag library to access portlet functionality. Any JSP pages that are called from a portlet can use these tags to get access to portlet objects, create URLs for links to the current portlet, or provide a unique identifier for named HTML elements. The recommended taglib declaration for any JSP pages that use the tag library is <body onload="initAJAX();"> <div id="pic"><img src="GetPicture.aspx picid=100" alt="not present" /></div> <input type="button" value="<<" id="btnPrev" onclick="DoPrev();" /> <input type="button" value=">>" id="btnNext" onclick="DoNext();" /> </body> To modify contents of any of the nodes, the XPathNavigator class provides a method called SetValue(), which accepts the new value and assigns it to the current node. Listing 4-15 shows how this method can be used. java upc-a Java UPC-A Generator | Barcode UPCA Generation in Java Class ...

Integrate UPC-A barcode generation function to Java applications for drawing UPC-A in Java . In your web.xml application deployment descriptor, you will need to map the portlet taglib URI to the location of the tag library descriptor (TLD) file: <taglib> <taglib-uri>http://java.sun.com/portlet</taglib-uri> <taglib-location>/WEB-INF/tags/portlet.tld</taglib-location> </taglib> Next, add a <script> tag to the head of your page, and add the following var declarations to it. They aren t part of a function within the <script> tag, so they are common to all functions. Listing 4-15. Modifying Content private void button3_Click(object sender, EventArgs e) { navigator.MoveToRoot(); navigator.MoveToFirstChild(); while (navigator.MoveToNext()) { navigator.MoveToFirstChild(); do { string id = navigator.GetAttribute("employeeid", ""); if (id == textBox1.Text) { navigator.MoveToFirstChild(); do { switch (navigator.Name) { case "firstname": navigator.SetValue(textBox2.Text); break; case "lastname": navigator.SetValue(textBox3.Text); break; case "homephone": navigator.SetValue(textBox4.Text); break; case "notes": navigator.SetValue(textBox5.Text); break; } } while (navigator.MoveToNext()); navigator.MoveToParent(); } } while (navigator.MoveToNext()); } } You do not need to add anything to the portlet.xml deployment descriptor to enable the tag library, because the tags are for the JSP pages, which are processed by the JSP compiler and servlet engine. var var var var var ajaxRequest cachedAjaxRequest currentPic = 100; theURL; theCachedURL; java upc-a racca3141/UPC: Build a UPC-A label. - GitHub

The <defineObjects> tag is used to define several objects from the calling portlet s request in the JSP page. You can use these objects from JSP scriptlets. The tag takes no attributes or content it s always used in this form: As before, the code finds out the <employee> node that is to be updated. The switch statement checks the Name property of XPathNavigator for the required node names (firstname, lastname, homephone, and notes). Inside each case, the SetValue() method is called on the navigator by passing the new value from the appropriate text box. As you step through the functions, you ll see the purpose of these. The first function that you ll need to implement is the initAJAX function called by the loading event of the page body. Here it is: These objects are the same ones that are included in the request object for a JSP or servlet in a portlet application. They can be accessed as request attributes from that request object. The <defineObjects> tag is a convenient shortcut for using these objects from a JSP . Here is an example that uses the renderRequest variable from the <defineObjects> JSP tag: Deleting a node is fairly simple. The DeleteSelf() method of XPathNavigator deletes the current node. After the node is successfully deleted, the cursor is moved to the parent node of the deleted node. Listing 4-16 shows the usage of DeleteSelf(). Listing 4-16. Deleting a Node private void button4_Click(object sender, EventArgs e) { navigator.MoveToRoot(); navigator.MoveToFirstChild(); while (navigator.MoveToNext()) { navigator.MoveToFirstChild(); do { string id = navigator.GetAttribute("employeeid", ""); if (id == textBox1.Text) { navigator.DeleteSelf(); } } while (navigator.MoveToNext()); } } As in the previous case, the code looks for a specific <employee> node. After it finds the node, it calls the DeleteSelf() method on the navigator. java upc-a BE THE CODER > Barcodes > Barcode4j Examples > Barcode UPC-A
