jqueyr判断checkbox组的选中(示例代码)

html:
复制代码 代码如下:
 
                       
                       
                       
                            批准   
                            不批准
                       
                   

jquery :
复制代码 代码如下:
$(function () {
    $(".checkboxListItem").change(    //教师
        function () {
            var $checkValue = $("input[name='checkItem']:checked").val();
            if ($checkValue == 3) {
                $("#slsa_approval").attr("checked", true);
                $("#slsa_noApproval").attr("checked", false);
            }
            else {
                $("#slsa_approval").attr("checked", false);
                $("#slsa_noApproval").attr("checked", true);
            }
        });
});

通过值的判断:
复制代码 代码如下:
 var checkCheckbox = $("#slsa_approval").attr("checked");
        if (checkCheckbox == true) {
            auditState = "3";
        } else {
            auditState = "4";
        }
