-//The Store contains the AjaxProxy as an inline configuration
-var store = new Ext.data.Store({
- model: 'User',
- proxy: {
- type: 'ajax',
- url : 'users.json'
- }
-});
-
-store.load();
-</code></pre>
- *
- * <p>Our example is going to load user data into a Store, so we start off by defining a {@link Ext.data.Model Model}
- * with the fields that we expect the server to return. Next we set up the Store itself, along with a {@link #proxy}
- * configuration. This configuration was automatically turned into an Ext.data.proxy.Ajax instance, with the url we
- * specified being passed into AjaxProxy's constructor. It's as if we'd done this:</p>
- *
-<pre><code>
-new Ext.data.proxy.Ajax({
- url: 'users.json',
- model: 'User',
- reader: 'json'
-});
-</code></pre>
- *
- * <p>A couple of extra configurations appeared here - {@link #model} and {@link #reader}. These are set by default
- * when we create the proxy via the Store - the Store already knows about the Model, and Proxy's default
- * {@link Ext.data.reader.Reader Reader} is {@link Ext.data.reader.Json JsonReader}.</p>
- *
- * <p>Now when we call store.load(), the AjaxProxy springs into action, making a request to the url we configured
- * ('users.json' in this case). As we're performing a read, it sends a GET request to that url (see {@link #actionMethods}
- * to customize this - by default any kind of read will be sent as a GET request and any kind of write will be sent as a
- * POST request).</p>
- *
- * <p><u>Limitations</u></p>
- *
- * <p>AjaxProxy cannot be used to retrieve data from other domains. If your application is running on http://domainA.com
- * it cannot load data from http://domainB.com because browsers have a built-in security policy that prohibits domains
- * talking to each other via AJAX.</p>
- *
- * <p>If you need to read data from another domain and can't set up a proxy server (some software that runs on your own
- * domain's web server and transparently forwards requests to http://domainB.com, making it look like they actually came
- * from http://domainA.com), you can use {@link Ext.data.proxy.JsonP} and a technique known as JSON-P (JSON with
- * Padding), which can help you get around the problem so long as the server on http://domainB.com is set up to support
- * JSON-P responses. See {@link Ext.data.proxy.JsonP JsonPProxy}'s introduction docs for more details.</p>
- *
- * <p><u>Readers and Writers</u></p>
- *
- * <p>AjaxProxy can be configured to use any type of {@link Ext.data.reader.Reader Reader} to decode the server's response. If
- * no Reader is supplied, AjaxProxy will default to using a {@link Ext.data.reader.Json JsonReader}. Reader configuration
- * can be passed in as a simple object, which the Proxy automatically turns into a {@link Ext.data.reader.Reader Reader}
- * instance:</p>
- *
-<pre><code>
-var proxy = new Ext.data.proxy.Ajax({
- model: 'User',
- reader: {
- type: 'xml',
- root: 'users'
- }
-});
-
-proxy.getReader(); //returns an {@link Ext.data.reader.Xml XmlReader} instance based on the config we supplied
-</code></pre>
- *
- * <p><u>Url generation</u></p>
- *
- * <p>AjaxProxy automatically inserts any sorting, filtering, paging and grouping options into the url it generates for
- * each request. These are controlled with the following configuration options:</p>
- *
- * <ul style="list-style-type: disc; padding-left: 20px;">
- * <li>{@link #pageParam} - controls how the page number is sent to the server
- * (see also {@link #startParam} and {@link #limitParam})</li>
- * <li>{@link #sortParam} - controls how sort information is sent to the server</li>
- * <li>{@link #groupParam} - controls how grouping information is sent to the server</li>
- * <li>{@link #filterParam} - controls how filter information is sent to the server</li>
- * </ul>
- *
- * <p>Each request sent by AjaxProxy is described by an {@link Ext.data.Operation Operation}. To see how we can
- * customize the generated urls, let's say we're loading the Proxy with the following Operation:</p>
- *
-<pre><code>
-var operation = new Ext.data.Operation({
- action: 'read',
- page : 2
-});
-</code></pre>
- *
- * <p>Now we'll issue the request for this Operation by calling {@link #read}:</p>
- *
-<pre><code>
-var proxy = new Ext.data.proxy.Ajax({
- url: '/users'
-});
-
-proxy.read(operation); //GET /users?page=2
-</code></pre>
- *
- * <p>Easy enough - the Proxy just copied the page property from the Operation. We can customize how this page data is
- * sent to the server:</p>
- *
-<pre><code>
-var proxy = new Ext.data.proxy.Ajax({
- url: '/users',
- pagePage: 'pageNumber'
-});
