We ll name this page, which tests the downloadText function, downloadTexthtml We start by including ajaxframeworkjs, which makes the downloadText function accessible to our JavaScript:

<html> <head> <title>Downloading Text With the Ajax Framework Library Pack</title> <script type = "text/javascript" src = "ajaxframeworkjs"></script>

Now we can add the two buttons to the test web page:

<form> <input type onclick = <input type onclick = </form> = "button" value = "Get message 1" "downloadText('datatxt', callbackMessage1)"> = "button" value = "Get message 2" "downloadText('data2txt', callbackMessage2)">

Note what we re doing here: we re passing the downloadText function the URL of the data to get (which is just "datatxt" or "data2txt" we re making the assumption that data txt and data2txt are in the same directory and on the same server as ajaxframeworkjs and downloadTexthtml, so we can use a relative URL here) and the callback function The callback function is named callbackMessage1 for button 1 and callbackMessage2 for button 2 In these callback functions, we just want to display the downloaded text in a <div> element that has the ID "targetDiv":

<body> <H1>Downloading Text With the Ajax Framework Library Pack</H1> <form> <input type = "button" value = "Get message 1" onclick = "downloadText('datatxt', callbackMessage1)">

Using Ajax Frameworks

<input type = "button" value = "Get message 2" onclick = "downloadText('data2txt', callbackMessage2)"> </form> <div id="targetDiv"> <p>The fetched data will go here</p> </div> </body>

Here s what the callback function callbackMessage1 looks like:

And here s what the callback function callbackMessage2 looks like:

Great; that does it Here s the whole page, downloadTexthtml, that tests the downloadText function:

<html> <head> <title>Downloading Text With the Ajax Framework Library Pack</title> <script type = "text/javascript" src = "ajaxframeworkjs"></script> <script language = "javascript"> function callbackMessage1(text)

Ajax: A Beginner s Guide

{ documentgetElementById("targetDiv")innerHTML = text; } function callbackMessage2(text) { documentgetElementById("targetDiv")innerHTML = text; } </script> </head> <body> <H1>Downloading Text With the Ajax Framework Library Pack</H1> <form> <input type onclick = <input type onclick = </form>

= "button" value = "Get message 1" "downloadText('datatxt', callbackMessage1)"> = "button" value = "Get message 2" "downloadText('data2txt', callbackMessage2)">

<div id="targetDiv"> <p>The fetched data will go here</p> </div> </body> </html>

You can see this page at work in Figure 5-1 When you click button 1, the correct data is indeed downloaded and displayed We re in business so far so good

Using Ajax Frameworks

Try This

Get downloadTexthtml to Work

Note that if you want to send data to the server with the HTTP GET method, you have to URL-encode that data That works with the downloadText function as well Here s a way to test whether you have access to a server that supports PHP, using the dataresponderphp script developed in 3:

< php if ($_GET["data"] == "1") { echo 'The server got a value of 1'; } if ($_GET["data"] == "2") { echo 'The server got a value of 2'; } >

Connect to this PHP script and send it data by using URL encoding, something like this:

When you click the first button, you should see The server got a value of 1, and when you click the second button, you should see The server got a value of 2
