cakephp - YUI DataTable get total number records

Question

I am new to YUI and I am using YUI 2 Datatable, I would like to alert if the total number of record is more than 4000 and not to render the table.

below is my piece of code.

this.myDataSource = new YAHOO.util.DataSource("<?php echo $html->url('/parser/dynload').'?params_array_serialized='.$params_array_serialized; ?>");

this.myDataTable = new YAHOO.widget.DataTable("gridbox", myColumnDefs,this.myDataSource, myConfigs);

I dont know how to get total number of record. Any one can help in this.

如果我没记错的话，this.myDataTable会有一个getRecordSet()方法返回一个RecordSet对象，该对象是 DataTable 存储其数据的地方。有RecordSet一个length（或者可能是count？）属性或者它是getLength()方法。无论如何，不​​管我不太记得的名字，但调试器会告诉你，RecordSet对象是它的关键。

我确实记得 YUI 的 API 文档的最后一个版本出错了，我相信该RecordSet对象被意外丢弃或放错了位置，所以你不会在那里找到它。
