+ <p>In this example, we set the <code>initialRequest</code> value in the DataTableDataSource plugin constructor so that the initial data is loaded first and then the DataTable is rendered in a separate call.</p>

+<h2>Populating Your DataTable with Remote Data using DataSource.IO</h2>
+<p>
+<strong>Note:</strong> be sure to add the <code>yui3-skin-sam</code> classname to the
+page's <code><body></code> element or to a parent element of the widget in order to apply
+the default CSS skin. See <a href="http://yuilibrary.com/yui/docs/tutorials/skins/">Understanding Skinning</a>.
+</p>
+<pre class="code prettyprint"><body class="yui3-skin-sam"> <!-- You need this skin class --></pre>
+
+<p>Your table can be easily populated with XML data from your back-end by creating a DataSource instance and using the DataTableDataSource plugin to load the data into a DataTable.</p>
+
+<p>Start with the <code>use()</code> statement:</p>
+
+<pre class="code prettyprint">YUI().use("datasource-io", "datasource-xmlschema", "datatable-datasource", function(Y) {
+});</pre>
+
+
+<p>Next create a DataSource.IO instance pointing to your data. (Note that in order to point the Yahoo! Local webservice, you would need to bypass cross-domain browser restrictions on XHR by creating a locally served proxy. You do not need to implement such a proxy when your data is accessed from the same domain.) Define the correct schema for the DataSourceJSONSchema plugin. This is a good time to call <code>sendRequest</code> to make sure the data returns as expected.</p>
+
+<pre class="code prettyprint">var dataSource = new Y.DataSource.IO({
+ source:"ylocal_proxy.php?zip=94089&query=chinese"
+});
+
+dataSource.plug(Y.Plugin.DataSourceXMLSchema, {
+ schema: {
+ resultListLocator: "Result",
+ resultFields: [
+ {key:"Title", locator:"*[local-name() ='Title']"},
+ {key:"Phone", locator:"*[local-name() ='Phone']"},
+ {key:"Rating", locator:"*[local-name()='Rating']/*[local-name()='AverageRating']"}
+ ]
+ }
+});
+
+dataSource.sendRequest({
+ callback: {
+ success: function (e) {
+ Y.log(e);
+ }
+ }
+});</pre>
+
+
+<p>Now that the DataSource is created properly, define the columns that you want your table to show. These columns map directly to the parameter names returned in the data.</p>
+
+<p>Now you are ready to create a DataTable using the columns you have defined. When you plug the instance with the DataTableDataSource plugin, point to your DataSource instance, and set an <code>initialRequest</code> value so that the initial data loads right way. Then call <code>render()</code> after the data response has been processed.</p>
+
+<pre class="code prettyprint">var dataSource = new Y.DataSource.IO({
+ source:"ylocal_proxy.php?zip=94089&query=chinese"
+});
+
+dataSource.plug(Y.Plugin.DataSourceXMLSchema, {
+ schema: {
+ resultListLocator: "Result",
+ resultFields: [
+ {key:"Title", locator:"*[local-name() ='Title']"},
+ {key:"Phone", locator:"*[local-name() ='Phone']"},
+ {key:"Rating", locator:"*[local-name()='Rating']/*[local-name()='AverageRating']"}
+ ]
+ }
+});
+
+var table = new Y.DataTable({
+ columns: ["Title", "Phone", "Rating"],
+ summary: "Chinese restaurants near 98089",
+ caption: "Table with XML data from same-domain script"
+});
+table.plug(Y.Plugin.DataTableDataSource, {
+ datasource: dataSource,
+ initialRequest: ""
+});
+
+dataSource.after("response", function() {
+ table.render("#pizza")}
+);</pre>
+
+
+<p>One final change you can make is to split the URL between the DataSource <code>source</code> value and the <code>request</code> value sent to the DataTableDataSource plugin. Splitting the URL this way facilitates making future requests to the same DataSource.
+
+<p>Here's the code to run the whole example:</p>
+
+<pre class="code prettyprint">YUI().use("datasource-get", "datasource-jsonschema", "datatable-datasource", function(Y) {
+ var dataSource = new Y.DataSource.IO({
+ source: "ylocal_proxy.php?"
+ });
+
+ dataSource.plug(Y.Plugin.DataSourceXMLSchema, {
+ schema: {
+ resultListLocator: "Result",
+ resultFields: [
+ {key:"Title", locator:"*[local-name() ='Title']"},
+ {key:"Phone", locator:"*[local-name() ='Phone']"},
+ {key:"Rating", locator:"*[local-name()='Rating']/*[local-name()='AverageRating']"}
+ ]
+ }
+ });
+
+ var table = new Y.DataTable({
+ columns: ["Title", "Phone", "Rating"],
+ summary: "Chinese restaurants near 98089",
+ caption: "Table with XML data from same-domain script"
+ });
+
+ table.plug(Y.Plugin.DataTableDataSource, {
+ datasource: dataSource,
+ initialRequest: "zip=94089&query=chinese"
+ });
+
+ dataSource.after("response", function() {
+ table.render("#pizza")}
+ );
+
+ // Make another request later
+ //table.datasource.load({request:"zip=94089&query=pizza"});
+});</pre>
