1、checkbox list选择

代码:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">  <title></title>  <script src="Scripts/jquery-1.7.min.js" type="text/javascript"></script>  <script type="text/javascript">    $(function () {      // 全选      $("#btnCheckAll").bind("click", function () {        $("[name = chkItem]:checkbox").attr("checked", true);      });       // 全不选      $("#btnCheckNone").bind("click", function () {        $("[name = chkItem]:checkbox").attr("checked", false);      });       // 反选      $("#btnCheckReverse").bind("click", function () {        $("[name = chkItem]:checkbox").each(function () {          $(this).attr("checked", !$(this).attr("checked"));        });      });       // 全不选      $("#btnSubmit").bind("click", function () {        var result = new Array();        $("[name = chkItem]:checkbox").each(function () {          if ($(this).is(":checked")) {            result.push($(this).attr("value"));          }        });         alert(result.join(","));      });    });  </script></head><body>  <div>    <input name="chkItem" type="checkbox" value="今日话题" />今日话题    <input name="chkItem" type="checkbox" value="视觉焦点" />视觉焦点    <input name="chkItem" type="checkbox" value="财经" />财经    <input name="chkItem" type="checkbox" value="汽车" />汽车    <input name="chkItem" type="checkbox" value="科技" />科技    <input name="chkItem" type="checkbox" value="房产" />房产    <input name="chkItem" type="checkbox" value="旅游" />旅游  </div>  <div>    <input id="btnCheckAll" type="button" value="全选" />    <input id="btnCheckNone" type="button" value="全不选" />    <input id="btnCheckReverse" type="button" value="反选" />    <input id="btnSubmit" type="button" value="提交" />  </div></body></html>
