Listing 12-31. Stopping and Starting Timers When a Key Is Pressed (SearchSuggestor.class.js) onQueryChanged : function(e) { clearTimeout(this.timer); this.timer = setTimeout(this.loadSuggestions.bind(this), this.delay * 1000); }, Now we must write the function to initiate the Ajax request and retrieve the search suggestions. First we retrieve the current query value from the form and trim it using strip() (remove the whitespace). Next we check the length of the query. If the query is empty or if it is the same as the previous query, we return from the function. If we didn t do this, then a new Ajax request would be performed even if the user simply pressed a key that didn t change the query (such as an arrow key). Once we determine the query can be submitted, we update the class query property to remember the query for the next time. At this stage, we can perform the Ajax request to retrieve the search results. We use the onSuggestionLoad() function as the callback handler for the Ajax request. Although we define that function in Listing 12-32, we don t actually do anything with the results yet. We will build on this function and the rest of this class later in the chapter. Listing 12-32. Initiating the Ajax Request and Handling the Response (SearchSuggestor.class.js) loadSuggestions : function() { var query = $F(this.input).strip(); if (query.length == 0 || query == this.query) return; this.query = query; var options = { parameters : 'q=' + query, onSuccess : this.onSuggestionLoad.bind(this) }; new Ajax.Request(this.url, options); }, onSuggestionLoad : function(transport) { var json = transport.responseText.evalJSON(true); } }; .net ean 13 reader .

I ll give an example of a simple replacement SSI handler later in the chapter. Of course, in Apache 2, you could simply have configured mod_include via the Includes filter instead, and the RemoveHandler directive wouldn t have been necessary. In addition, mod_include could then process any SSIs you chose not to process, so the SSI parser could then limit itself to just processing your custom SSI extensions. You want to produce a Web page with a randomly selected banner displayed each time it s called. You could choose to do this in several ways: a Java applet, an embedded JavaScript script, or an ordinary CGI script called by an SSI. In this section, you ll implement a handler. First, edit the configuration file to trigger a user-defined handler whenever a file with the extension .random is seen: ean 128 word 2007, birt code 39, birt ean 13, microsoft word 2007 qr code generator, birt upc-a, birt gs1 128 .net ean 13 reader EAN13 Barcode Control - CodeProject

It doesn t actually have to contain anything because it s simply a device to trigger the handler. However, Apache requires that the file exists to trigger the handler when it s accessed. On Unix, you can do this by simply typing this: .net ean 13 reader Packages matching ean-13 - NuGet Gallery

C# . NET EAN - 13 recognition reader control component is used to scan & read EAN - 13 barcode from image in C#. NET class applications. Although we have not yet completed the SearchSuggestor class, we can add it to our site template. To do this, we must first load the SearchSuggestor.class.js file and then load the class in the onload callback we created in the scripts.js file earlier in the book. Listing 12-33 shows the changes that are to be made to header.tpl in ./templates to load the SearchSuggestor.class.js file. Listing 12-33. Loading the SearchSuggestor Class in the Site Template (header.tpl) <!-- // ... other code --> <script type="text/javascript" src="/js/SearchSuggestor.class.js"></script> <script type="text/javascript" src="/js/scripts.js"></script> <!-- // ... other code --> At this stage, however, the SearchSuggestor class is not actually being used. We must modify the init() function in the scripts.js file to bind the class to the query text input. As mentioned previously, the argument to the SearchSuggestor function is the ID of the container holding the search form in footer.tpl. Listing 12-34 shows the code we add to the scripts.js file. Listing 12-34. Instantiating the SearchSuggestor Class on Page Load (scripts.js) function init(e) { // ... other code new SearchSuggestor('search'); } Since Apache 1.3.10, this step is no longer required. Finally, create the randomize script, which provides the handler to choose a random image and place it in the CGI bin directory with execute permission. It chooses the image by looking in the directory of the originally requested URL and making a list of all files with a given extension, in this case, .gif: #!/usr/bin/perl -w # # randomize.gi - return a random image $MediaType = "image/gif"; $Extension = "gif"; # enable autoflush so image is written as it is read $|=1; # collect all images with the right extension in the URL directory $filepath = "$ENV{'PATH_TRANSLATED'}"; $filepath =~ s/(}/.*)\/[^\/]+.*$/$1/; chdir $filepath; @files = glob "*.$Extension"; # pick a random file srand(time ^ $$); $num = int(rand(@files)); $imagefile = "$filepath/$files[$num]"; # Send headers print "Content Type: $MediaType\nCache-Control: no-cache\n\n"; # Read the file and write it to the output open(IMAGE, $imagefile); print while <IMAGE>; close(IMAGE); .net ean 13 reader .
