DataGrid GridView 单页javascript 表头排序

JS代码如下：

<script>
var curObj;
var shell = 1;
function sortTable(L) {
 var start=new Date()
 var i;
 var DataGrid1 = document.getElementByIdx_x_x("DataGrid1");
var theRows=new Array();
for (i = 1; i < DataGrid1.rows.length-1; i++) {
    var str = "";
    var tds = DataGrid1.rows[i].getElementsByTagName_r("td");
    var cloum = tds[L].innerText;
    if (L == 7 || L == 8 || L == 9) {
        cloum = tds[L].innerHTML;
    }
    var html = DataGrid1.rows[i].outerHTML;
    DataGrid1.rows[i].outerHTML);
    theRows[i - 1] = new Array(cloum,html);
}
if (shell==1){
shell=2;
//根据不同类型的列选择不同的排序方式，据实际情况定
 switch(parseInt(L)){
 case 5:
  theRows.sort(sortRows);
  break;
 case 4,3:
  theRows.sort(sortRows1);
  break;
 default:
  theRows.sort(sortRows2);
  }
}
else{
shell=1;
 switch(parseInt(L)){
 case 5:
  theRows.sort(sortRows0);
  break;
 case 4,3:
  theRows.sort(sortRows11);
  break;
 default:
  theRows.sort(sortRows22);
 }
}
var str=''
for(i=0;i<theRows.length;i++) {
 str+=theRows[i][1];
 }
 DataGrid1.outerHTML = '<table border="0" cellPadding="-1" cellSpacing="0" BorderColor="White" width="100%" bordercolor="#ffffff" name="DataGrid1" id="DataGrid1">'  + DataGrid1.rows[0].outerHTML + str + '</table>'
curObj=null;

return ;
}
//降序－－－－－－－－－－－－－－－－－－－
//数值类型的列进行排序
function sortRows(x,y) {
  if(x[0]>y[0]) return -1;
  else if(x[0]<y[0]) return 1;
  else return 0;
}
//金额类型的列进行排序
function sortRows1(x, y) {
    var aa = x[0].replace("￥", "").replace(",", "");
    var bb = y[0].replace("￥", "").replace(",", "");
  if(parseInt(aa)>parseInt(bb)) return -1;
  else if(parseInt(aa)<parseInt(bb)) return 1;
  else return 0;
}
//处理字符串列的排序
function sortRows2(x,y) {
    return y[0].localeCompare(x[0]);
}
//end 降序－－－－－－－－－－－－－－－－－－－－－
//升序－－－－－－－－－－－－－－－－－－ －
//数值类型的列进行排序
function sortRows0(x,y) {
  if(x[0]<y[0]) return -1;
  else if(x[0]>y[0]) return 1;
  else return 0;
}
//金额类型的列进行排序
function sortRows11(x, y) {
    var aa = x[0].replace("￥", "").replace(",", "");
    var bb = y[0].replace("￥", "").replace(",", "");
  if(parseInt(aa)<parseInt(bb)) return -1;
  else if(parseInt(aa)>parseInt(bb)) return 1;
  else return 0;
}
//处理字符串类型的列排序
function sortRows22(x,y) {
    return x[0].localeCompare(y[0]);
}
//end 升序－－－－－－－－－－－－－－－－－－－－－
  </script>

后台调用方法：

private void DataGrid1_ItemDataBound(object sender, DataGridItemEventArgs e)
{
            if (e.Item.ItemType == ListItemType.Header)
            {
                e.Item.Cells[2].Attributes["onClick"] = "javascript:sortTable(1)";
                e.Item.Cells[3].Attributes["onClick"] = "javascript:sortTable(2)";
                e.Item.Cells[4].Attributes["onClick"] = "javascript:sortTable(3)";
                e.Item.Cells[5].Attributes["onClick"] = "javascript:sortTable(4)";
                e.Item.Cells[6].Attributes["onClick"] = "javascript:sortTable(5)";
                e.Item.Cells[8].Attributes["onClick"] = "javascript:sortTable(7)";
                e.Item.Cells[9].Attributes["onClick"] = "javascript:sortTable(8)";
                e.Item.Cells[10].Attributes["onClick"] = "javascript:sortTable(9)";
            }
}
