基础查询，多选，全选，分页功能

<scripttype="text/javascript">

$(document).ready(function(){//预加载

$('#chkAll').click(

function(){

$("INPUT[type='checkbox']").attr('checked',$('#chkAll').is(':checked'));

});

//$('#chkAll').click(

function(){

$("input[name='chkItem']").each(function(){

this.checked=$('#chkAll').is(':checked');

});

});

$("#DropDownList1").change(function(){

window.location.href="整体.aspx?page="+$("#hidPage").val()+"&score="+$(this).val()+"&search="+$("#searchBox").val();

});

});

<asp:DropDownListID="DropDownList1"runat="server">

<asp:ListItemText="查询分数"Value="0"></asp:ListItem>

<asp:ListItemText="90分以上"Value="90and100"></asp:ListItem>

</asp:DropDownList>

<asp:CheckBoxID="chkAll"runat="server"Text="全选"/>

后台代码的取值stringscore=HttpContext.Current.Request["score"];
