use of fnGetSelectedData method

Recently I wanted to select a data row and click on a tabletool plugin button which had to take me to a page based on the selected row's id. I achieved this with the help of Allan. Excellent support. Thank you! I am posting this here in case anyone needed help. This was achieved using fnGetSelectedData method.

{ 
	"sExtends": "text",
	"sButtonText": "My details",
	"fnClick": function (nButton, oConfig) {
		var sData = this.fnGetSelectedData(oConfig);
		if(sData.length == 1) {
			var rowId = sData[0].rowId
			var href = "${pageContext.request.contextPath}/admin/my_home.jsp?rowId=" + rowId;
			$('#ui-tabs-2').load(href);
			return false;
		} 
	}
}
