YUI Library Examples: DataTable Control: Client-side Sorting

Sample Code for this Example

Data:


1	YAHOO.example.Data = {
2	areacodes: [
3	{areacode: "201", state: "New Jersey"},
4	{areacode: "202", state: "Washington, DC"},
5	{areacode: "203", state: "Connecticut"},
6	...
7	]
8	}
	view plain \| print \| ?

CSS:


1	/* No custom CSS. */
	view plain \| print \| ?

Markup:


1	<div id="sort"></div>
	view plain \| print \| ?

JavaScript:


1	YAHOO.util.Event.addListener(window, "load", function() {
2	YAHOO.example.CustomSort = function() {
3	// Custom sort handler to sort by state and then by areacode
4	// where a and b are Record instances to compare
5	var sortStates = function(a, b, desc) {
6	// Deal with empty values
7	if(!YAHOO.lang.isValue(a)) {
8	return (!YAHOO.lang.isValue(b)) ? 0 : 1;
9	}
10	else if(!YAHOO.lang.isValue(b)) {
11	return -1;
12	}
13
14	// First compare by state
15	var comp = YAHOO.util.Sort.compare;
16	var compState = comp(a.getData("state"), b.getData("state"), desc);
17
18	// If states are equal, then compare by areacode
19	return (compState !== 0) ? compState : comp(a.getData("areacode"), b.getData("areacode"), desc);
20	};
21
22	var myColumnDefs = [

28	myDataSource.responseType = YAHOO.util.DataSource.TYPE_JSARRAY;
29	myDataSource.responseSchema = {
30	fields: ["areacode","state"]
31	};
