<h2><code>ic-append-from</code> - The Append From Attribute</h2>
<h3>Summary</h3>
<p>The <code>ic-append-from</code> attribute binds a given HTML element's children to a URL. It does not
cause any requests to happen by itself, but it can respond to events caused by other attributes.</p>
<p>When Intercooler issues a request for an element with an <code>ic-append-from</code>, it will issue a
<code>GET</code>
and will append the resulting HTML fragment as children of the current element. If you wish to limit the total
number of children on of an element, you can use the <a
href="ic-limit-children.html"><code>ic-limit-children</code></a>
attribute.</p>
<h3>Syntax</h3>
<p>The value of the attribute should be a valid relative path (e.g. <code>ic-append-from="/foo/bar"</code>).</p>
<h3>Dependencies</h3>
<p><code>ic-append-from</code> implies a dependency on its path, and Intercooler will issue requests for elements
whenever it detects an action that the path depends on. See <a href="/dependencies.html">Dependencies</a> for
more information.</p>
<h3>Example</h3>
<p>Here is a simple example, using a poll interval to update:</p>
<pre>
<ul ic-append-from="/list_src" ic-poll="2s" ic-limit-children="5"></ul>
</pre>
<div class="live-demo">
<script>
(function () {
$.mockjax({
url: '/list_src',
response: function () {
function randIp() {
function getOctet() {
return Math.round(Math.random()*255);
}
//generate the ipaddress
return getOctet() + '.' + getOctet() + '.' + getOctet() + '.' + getOctet();
}
this.responseText = "<li>Being looked at by " + randIp() + "</li>";
}
});
})();
</script>
<ul ic-append-from="/list_src" ic-poll="2s" ic-limit-children="5"></ul>
