Jquery获取选中的checkbox的值

1、Jquery获取选中的checkbox的值（多选）

   <span><input name=\'cbServerType\' type=\'checkbox\' value=\'1\'  />1111111</span>
   <span><input name=\'cbServerType\' type=\'checkbox\' value=\'2\'  />2222222</span>
   <span><input name=\'cbServerType\' type=\'checkbox\' value=\'3\'  />3333333</span>
   <span><input name=\'cbServerType\' type=\'checkbox\' value=\'4\'  />4444444</span>
   <span><input name=\'cbServerType\' type=\'checkbox\' value=\'5\' />5555555</span>

 

<script type="text/javascript">
        $(function () {

            $("input[name=\'cbServerType\']:checkbox").click(function () {
                var type = \'\';
                $("input[name=\'cbServerType\']:checkbox").each(function () {
                    if ($(this).attr("checked")) {
                        type += $(this).attr(\'value\') + \'|\';
                    }
                });
                alert(type);
                $("#txtServerType").val(type);
            });
        }); 
    </script>

2、Jquery从数据库读取值选中相应的checkbox（多选，以特定字符分割）

 

 <span><input name=\'cbServerType\' type=\'checkbox\' value=\'1\'  />1111111</span>
<span><input name=\'cbServerType\' type=\'checkbox\' value=\'2\'  />2222222</span>
<span><input name=\'cbServerType\' type=\'checkbox\' value=\'3\'  />3333333</span>
<span><input name=\'cbServerType\' type=\'checkbox\' value=\'4\'  />4444444</span>
<span><input name=\'cbServerType\' type=\'checkbox\' value=\'5\' />5555555</span>
   
<input type="hidden" id="txtServerType" name="txtServerType" runat="server" value="1|2|3"  />

 

<script type="text/javascript">
        $(function () {
            var str = new String();
            var arr = new Array();
            str = $("#txtServerType").val();
            arr = str.split(\'|\');
            for (var i = 0; i < arr.length; i++) {
                $("input[name=\'cbServerType\'][value=\'" + arr[i] + "\']").attr("checked", true);
            }
        }); 
    </script>
