<h1>Quickstart Example: Getting a Script File with YUI Get</h1>
<div class="exampleIntro">
<p>This example explores the simplest and most common use case for the <a href="http://developer.yahoo.com/yui/get">YUI Get Utility</a>: fetching a script with <code>YAHOO.util.Get.script()</code> and making use of its contents.</p>
<p>Click the button to retrieve the script and output its data to the blue box. The tutorial below gives you a full description of how to use this technique.</p>
</div>
<!--BEGIN SOURCE CODE FOR EXAMPLE =============================== -->
<div>
<button id="getScript">Get Data from Script</button>
</div>
<pre id="returnedData">
Data returned from the loaded script will appear here after you click the button above.
</pre>
<script language="JavaScript">
(function() {
//We'll use a YUI Button to actuate our request for the script:
var button = new YAHOO.widget.Button("getScript", {type: "link"});
//When the button is clicked, we'll make the script request:
button.on("click", function() {
YAHOO.log("Button was clicked; loading script with Get Utility.", "info", "example");
//We have a .js file at assets/simple_get.js. We will get
//that script with the Get Utility:
YAHOO.util.Get.script("../get/assets/simple_get.js", {
//ALL OF THE CONFIGURATION OPTIONS BELOW ARE OPTIONAL;
//IN MANY CASES, YOU'LL NEED ONLY TO DEFINE YOUR SUCCESS/
//FAILURE HANDLERS.
//callback to fire when the script is successfully loaded:
onSuccess: function(obj) {
YAHOO.log("Success handler was called. Transaction ID: " + obj.tId, "info", "example");
document.getElementById("returnedData").innerHTML = YAHOO.lang.dump(YAHOO.simple_get.data, 3);
},
//callback to fire if the script does not successfully load:
onFailure: function(o) {
YAHOO.log("Failure handler was called. Transaction ID: " + obj.tId, "info", "example");
},
//context under which success and failure handlers should run;
//default is the current window, which we'll use for this example:
scope: window,
//by default, the script will be added to the current
//window; use this property to override that default
//(we're just using the default in this example):
win: window,
//will be passed as a member of the callback object to
//the success or failure handler:
data: {testData: "value"},
//For Safari 2.x, which does not support the script's onload
//event to determine when the script is loaded; instead, Get
//will check for the presence of this varName (which is
//defined in the script we're retrieving) and use its presence
//to determine when the script has been successfully loaded:
varName: ["YAHOO.simple_get.data"]
});
});
})();
</script>
