效果图如下Aspx 代码Js 部分function CheckAll() /点击全部选择，选取本页面全部记录/因为在Form1中找不到chkSel的CheckBox,所以只好遍历整个documentvar cked = false;cked = document.getElementById(chkSelAll).checked;for (var i = 0; i Gridview 部分全选cs 部分protected void _Del_Click(object sender, EventArgs e)bool flag = true;for (int i = 0; i this.commentview.Rows.Count; i+)bool ischecked = (CheckBox)commentview.Rowsi.FindControl(chkSel).Checked;if (ischecked)string _comtitle = commentview.DataKeysi.Value.ToString();string sql = delete from comment where comtitle= + _comtitle + and username= + Sessionusername + ;comsql.DB.ExecuteNoReturn(sql);flag = false;if (flag)Page.ClientScript.RegisterStartupScript(this.GetType(), scriptKey, alert(提示信息没有选择数据);, true);else Response.Redirect(apply.aspx);bindcom();
