Jquery实现三层遍历删除功能代码

aspx页：


代码如下:

<script src="Jquery1.7.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$('#Checkbox1').click(function () {
if ($('#Checkbox1').is(':checked')) {
$('td input').attr('checked', true);
}
else { $('td input').attr('checked', false); }
})
$('#Checkbox2').click(function () {
$('td input').each(function () {
$(this).attr('checked', !$(this).attr('checked'))
})
})
})
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="Checkbox1" type="checkbox" />全选<input id="Checkbox2" type="checkbox" />反选<asp:Button
ID="Button1" runat="server" Text="删除" onclick="Button1_Click" />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="选择">
<ItemTemplate>
<asp:CheckBox ID="CheckBox3" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Id" HeaderText="编号" />
<asp:BoundField DataField="NewsTitle" HeaderText="标题" />
<asp:BoundField DataField="NewsContent" HeaderText="新闻内容">
<ItemStyle Width="200px" />
</asp:BoundField>
<asp:BoundField DataField="NewsCreator" HeaderText="创建者" />
<asp:BoundField DataField="CreateTime" HeaderText="创建时间" />
</Columns>
</asp:GridView>
</div>
</form>

后台cs文件：


代码如下:

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
load();
}
}
private void load()//就实现绑定
{
Jquery三层实现删除功能.Model.T_News mm = new Model.T_News();
Jquery三层实现删除功能.BLL.T_News bb = new BLL.T_News();
string sqlwhere = "Id<25";
ds = bb.GetList(sqlwhere);//获取dataset绑定
this.GridView1.DataSource = ds;
GridView1.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
//遍历每一行
foreach (GridViewRow item in GridView1.Rows)//一定要记住这里是gridviewrow不是datarow
{
CheckBox cb = (CheckBox)item.FindControl("CheckBox3");//找到这个选中项
if (cb.Checked)//选中
{

if (bb.DeleteList(item.Cells[1].Text))//调用bb.DeleteList(id）删除
{
Response.Write("删除成功");
}
load();
