我的代码:

$(this).closest("tr").after("<tr><td></td><td colspan = '999'>" + $(this).next().html() + "</td></tr>")

}
function Check_Click(objRef) {
//Get the Row based on checkbox
var row = objRef.parentNode.parentNode;
//Get the reference of GridView
var GridView = row.parentNode;
//Get all input elements in Gridview
var inputList = GridView.getElementsByTagName("input");
for (var i = 0; i < inputList.length; i++) {
//The First element is the Header Checkbox
var headerCheckBox = inputList[0];
//Based on all or none checkboxes
//are checked check/uncheck Header Checkbox
var checked = true;
if (inputList[i].type == "checkbox" && inputList[i] != headerCheckBox) {
if (!inputList[i].checked) {
checked = false;
break;
}
}
}
headerCheckBox.checked = checked;
}
function checkAll(objRef) {

var inputList = GridView.getElementsByTagName("input");
for (var i = 0; i < inputList.length; i++) {
//Get the Cell To find out ColumnIndex

当我选中复选框时,我需要打开mu子gridview。 请给我一些指导。
