1.控制checkbo只能选择其中一项
想用radiobox做单选题的选项，但是为了便于取值要用服务器空间，带来的麻烦就是不能使用name属性控制他们属于同一个域，现在使用checkbox+js的方式来实现radiobox的效果。
html代码：
<li class="liStyle"> 1. 阿斯顿按时<label class="fillTims" style="display: none" id="selectTips">请选择</label> <!--begin选项--> <ul> <li class="liStyle2"> <span id="labOption">A </span>.阿萨德发<input type="hidden" value="1" id="hidID" name="repSingle$ctl00$repSingleChoices$ctl00$hidID"> <input type="checkbox" name="repSingle$ctl00$repSingleChoices$ctl00$cheSingleChoice" id="cheSingleChoice"></li> <li class="liStyle2"> <span id="labOption">B </span>.阿萨德发<input type="hidden" value="2" id="hidID" name="repSingle$ctl00$repSingleChoices$ctl01$hidID"> <input type="checkbox" name="repSingle$ctl00$repSingleChoices$ctl01$cheSingleChoice" id="cheSingleChoice"></li> <li class="liStyle2"> <span id="labOption">C </span>.阿斯顿<input type="hidden" value="3" id="hidID" name="repSingle$ctl00$repSingleChoices$ctl02$hidID"> <input type="checkbox" name="repSingle$ctl00$repSingleChoices$ctl02$cheSingleChoice" id="cheSingleChoice"></li> </ul> <!--end选项--> <br> </li>
js代码：
//fun1_1 单选题只能选中选项其一 function mutipleCheckAction() { $("ul#ulSingle>li.liStyle>ul>li.liStyle2>:checkbox").click(function () { var count = $("ul#ulSingle>li.liStyle>ul>li.liStyle2>:checkbox").length; for (var i = 0; i < count; i++) { $("ul#ulSingle>li.liStyle>ul>li.liStyle2>:checkbox:eq(" + i + ")").attr("checked", false) } $(this).attr("checked", true); }) }
2.checkbox的常见方法
常用的方法有全选，全部选，反选等
html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>
用checkbox本身实现全选和反选
<!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 () { // chkAll全选事件 $("#chkAll").bind("click", function () { $("[name = chkItem]:checkbox").attr("checked", this.checked); }); // chkItem事件 $("[name = chkItem]:checkbox").bind("click", function () { var $chk = $("[name = chkItem]:checkbox"); $("#chkAll").attr("checked", $chk.length == $chk.filter(":checked").length); }) }); </script> </head> <body> <table id="tb"> <thead> <tr> <td><input id="chkAll" type="checkbox" /></td> <td>分类名称</td> </tr> </thead> <tbody> <tr> <td><input name="chkItem" type="checkbox" value="今日话题" /></td> <td>今日话题</td> </tr> <tr> <td><input name="chkItem" type="checkbox" value="视觉焦点" /></td> <td>视觉焦点</td> </tr> <tr> <td><input name="chkItem" type="checkbox" value="财经" /></td> <td>财经</td> </tr> <tr> <td><input name="chkItem" type="checkbox" value="汽车" /></td> <td>汽车</td> </tr> <tr> <td><input name="chkItem" type="checkbox" value="科技" /></td> <td>科技</td> </tr> <tr> <td><input name="chkItem" type="checkbox" value="房产" /></td> <td>房产</td> </tr> <tr> <td><input name="chkItem" type="checkbox" value="旅游" /></td> <td>旅游</td> </tr> </tbody> </table> </body> </html>
