<p><u>Retrieving Data</u></p>
<p>A Store object may access a data object using:<div class="mdetail-params"><ul>
<li><a href="output/Ext.data.Store.html#Ext.data.Store-proxy" ext:member="proxy" ext:cls="Ext.data.Store">configured implementation</a> of <a href="output/Ext.data.DataProxy.html" ext:cls="Ext.data.DataProxy">DataProxy</a></li>

<li><a href="output/Ext.data.Store.html#Ext.data.Store-loadData" ext:member="loadData" ext:cls="Ext.data.Store">loadData</a> to manually pass in data</li>
</ul></div></p>
<p><u>Reading Data</u></p>
<p>A Store object has no inherent knowledge of the format of the data object (it could be
an Array, XML, or JSON). A Store object uses an appropriate <a href="output/Ext.data.Store.html#Ext.data.Store-reader" ext:member="reader" ext:cls="Ext.data.Store">configured implementation</a>
of a <a href="output/Ext.data.DataReader.html" ext:cls="Ext.data.DataReader">DataReader</a> to create <a href="output/Ext.data.Record.html" ext:cls="Ext.data.Record">Record</a> instances from the data
object.</p>
<p><u>Store Types</u></p>
<p>There are several implementations of Store available which are customized for use with
a specific DataReader implementation. Here is an example using an ArrayStore which implicitly
creates a reader commensurate to an Array data object.</p>
<pre><code><b>var</b> myStore = <b>new</b> Ext.data.ArrayStore({
fields: [<em>'fullname'</em>, <em>'first'</em>],
idIndex: 0 <i>// id <b>for</b> each record will be the first element</i>
});</code></pre>
<p>For custom implementations create a basic <a href="output/Ext.data.Store.html" ext:cls="Ext.data.Store">Ext.data.Store</a> configured as needed:</p>
<pre><code><i>// create a <a href="output/Ext.data.Record.html" ext:cls="Ext.data.Record">Record</a> constructor:</i>
<b>var</b> rt = Ext.data.Record.create([
{name: <em>'fullname'</em>},
{name: <em>'first'</em>}
]);
<b>var</b> myStore = <b>new</b> Ext.data.Store({
<i>// explicitly create reader</i>
reader: <b>new</b> Ext.data.ArrayReader(
{
idIndex: 0 <i>// id <b>for</b> each record will be the first element</i>
},
rt <i>// recordType</i>
)
});</code></pre>
<p>Load some data into store (note the data object is an array which corresponds to the reader):</p>
<pre><code><b>var</b> myData = [
[1, <em>'Fred Flintstone'</em>, <em>'Fred'</em>], <i>// note that id <b>for</b> the record is the first element</i>
[2, <em>'Barney Rubble'</em>, <em>'Barney'</em>]
];
myStore.loadData(myData);</code></pre>
<p>Records are cached and made available through accessor functions. An example of adding
a record to the store:</p>
<pre><code><b>var</b> defaultData = {
fullname: <em>'Full Name'</em>,
first: <em>'First Name'</em>
};
<b>var</b> recId = 100; <i>// provide unique id <b>for</b> the record</i>
<b>var</b> r = <b>new</b> myStore.recordType(defaultData, ++recId); <i>// create <b>new</b> record</i>
myStore.<a href="output/Ext.data.Store.html#Ext.data.Store-insert" ext:member="insert" ext:cls="Ext.data.Store">insert</a>(0, r); <i>// insert a <b>new</b> record into the store (also see <a href="output/Ext.data.Store.html#Ext.data.Store-add" ext:member="add" ext:cls="Ext.data.Store">add</a>)</i></code></pre>
<p><u>Writing Data</u></p>
<p>And <b>new in Ext version 3</b>, use the new <a href="output/Ext.data.DataWriter.html" ext:cls="Ext.data.DataWriter">DataWriter</a> to create an automated, <a href="http://extjs.com/deploy/dev/examples/writer/writer.html">Writable Store</a>

<br><p><b><u>DOM events from ExtJs <a href="output/Ext.Component.html" ext:cls="Ext.Component">Components</a></u></b></p>
<br><p>While <i>some</i> ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this
is usually only done when extra value can be added. For example the <a href="output/Ext.DataView.html" ext:cls="Ext.DataView">DataView</a>'s
<b><code><a href="output/Ext.DataView.html#Ext.DataView-click" ext:member="click" ext:cls="Ext.DataView">click</a></code></b> event passing the node clicked on. To access DOM
events directly from a Component's HTMLElement, listeners must be added to the <i><a href="output/Ext.Component.html#Ext.Component-getEl" ext:member="getEl" ext:cls="Ext.Component">Element</a></i> after the Component
has been rendered. A plugin can simplify this step:<pre><code><i>// Plugin is configured <b>with</b> a listeners config object.</i>
<i>// The Component is appended to the argument list of all handler functions.</i>
Ext.DomObserver = Ext.extend(Object, {
constructor: <b>function</b>(config) {
this.listeners = config.listeners ? config.listeners : config;
},
<i>// Component passes itself into plugin's init method</i>
init: <b>function</b>(c) {
<b>var</b> p, l = this.listeners;
<b>for</b> (p <b>in</b> l) {
<b>if</b> (Ext.isFunction(l[p])) {
l[p] = this.createHandler(l[p], c);
} <b>else</b> {
l[p].fn = this.createHandler(l[p].fn, c);
}
}
<i>// Add the listeners to the Element immediately following the render call</i>
c.render = c.render.<a href="output/Function.html#Function-createSequence" ext:member="createSequence" ext:cls="Function">createSequence</a>(<b>function</b>() {
<b>var</b> e = c.getEl();
<b>if</b> (e) {
e.on(l);
}
});
},
createHandler: <b>function</b>(fn, c) {
<b>return</b> <b>function</b>(e) {
fn.call(this, e, c);
};
}
});
<b>var</b> combo = <b>new</b> Ext.form.ComboBox({
<i>// Collapse combo when its element is clicked on</i>
plugins: [ <b>new</b> Ext.DomObserver({
click: <b>function</b>(evt, comp) {
comp.collapse();
}

<b>Combining Options</b><br>
Using the options argument, it is possible to combine different types of listeners:<br>
<br>
A delayed, one-time listener.
<pre><code>myDataView.on(<em>'click'</em>, this.onClick, this, {
single: true,
delay: 100
});</code></pre>
<p>
<b>Attaching multiple handlers in 1 call</b><br>
The method also allows for a single argument to be passed which is a config object containing properties
which specify multiple handlers.
<p>
<pre><code>myGridPanel.on({
<em>'click'</em> : {
fn: this.onClick,
scope: this,
delay: 100
},
<em>'mouseover'</em> : {
fn: this.onMouseOver,
scope: this
},
<em>'mouseout'</em> : {
fn: this.onMouseOut,
scope: this
}
});</code></pre>
<p>
Or a shorthand syntax:<br>
<pre><code>myGridPanel.on({
<em>'click'</em> : this.onClick,
<em>'mouseover'</em> : this.onMouseOver,
<em>'mouseout'</em> : this.onMouseOut,
scope: this
});</code></pre></div></li></ul><strong>Returns:</strong><ul><li>void</li></ul></div></div></div></td><td class="msource"><a href="output/Ext.util.Observable.html#addListener" ext:member="#addListener" ext:cls="Ext.util.Observable">Observable</a></td></tr><tr class="method-row expandable "><td class="micon"><a href="#expand" class="exi"> </a></td><td class="sig"><a id="Ext.data.Store-addSorted"></a><b><a href="source/Store.html#method-Ext.data.Store-addSorted">addSorted</a></b>( <code>Ext.data.Record record</code> )
