# YUI Library Examples: DataTable Control (beta): Client-side Sorting

# DataTable Control (beta): Client-side Sorting

A custom sort handler has been defined in this example to enable custom nested sorting, such that clicking on the "States" Column will sort by states, and then by area code.

View example in new window.

## Sample Code for this Example

Data:

YAHOO.example.Data = { areacodes: [ {areacode: "201", state: "New Jersey"}, {areacode: "202", state: "Washington, DC"}, {areacode: "203", state: "Connecticut"}, ... ] }

CSS:

/* No custom CSS. */

Markup:

<div id="sort"></div>

JavaScript:

YAHOO.util.Event.addListener(window, "load", function() { YAHOO.example.CustomSort = new function() { // Custom sort handler to sort by state and then by areacode // where a and b are Record instances to compare this.sortStates = function(a, b, desc) { // Deal with empty values if(!YAHOO.lang.isValue(a)) { return (!YAHOO.lang.isValue(b)) ? 0 : 1; } else if(!YAHOO.lang.isValue(b)) { return -1; } // First compare by state var comp = YAHOO.util.Sort.compare; var compState = comp(a.getData("state"), b.getData("state"), desc); // If states are equal, then compare by areacode return (compState !== 0) ? compState : comp(a.getData("areacode"), b.getData("areacode"), desc); }; var myColumnDefs = [ {key:"areacode",label:"Area Codes",sortable:true}, {key:"state",label:"States",sortable:true,sortOptions:{sortFunction:this.sortStates}} ]; this.myDataSource = new YAHOO.util.DataSource(YAHOO.example.Data.areacodes); this.myDataSource.responseType = YAHOO.util.DataSource.TYPE_JSARRAY; this.myDataSource.responseSchema = { fields: ["areacode","state"] }; this.myDataTable = new YAHOO.widget.DataTable("sort", myColumnDefs, this.myDataSource, {sortedBy:{key:"areacode", dir:"asc"}}); }; });
