jquery验证在IE7中不起作用，但在IE8中起作用

我已经设置了一些自定义规则，用于根据是否从下拉框中选择项目来验证字段

下拉列表中有3个值

请选择 没有显示 拒绝 如果用户选择未显示日期选择器，则必须输入有效日期 如果用户选择拒绝，则会出现另一个下拉列表，用户必须从中选择一个值

问题是它在IE8中工作，但在IE7中不工作。想法

我已按如下方式设置了此功能：

    this.SetupValidations = function() {
            //validations
            LLNP4.validate('#uxReferralAssessmentDetailsForm',
                {
            rules: {
                assessmentDecision: { requiredSelect: "0" },
                NoShowDate: { required: othis.clientDidNotShowValidation },
                DeclinedReason: { requiredSelect: othis.clientDeclinedValidation }
                    }
                });
            }


     this.clientDidNotShowValidation = function() {
            if ($("#uxassessmentDecision option:selected").text().toUpperCase() == "DID NOT SHOW")
            { return true; }
            else
            { return false; }
        }


        this.clientDeclinedValidation = function() {
            if ($("#uxassessmentDecision option:selected").text().toUpperCase() == "DECLINED")
            { return "0"; }
            else
            { return "1"; }
        }


this.ValidateReferralAssessmentSubmission = function() {
        othis.SetupValidations();
        if ($("#uxReferralAssessmentDetailsForm").valid()) {
            return true;
        }
        else {
            return false;
        }
    }


this.OnAssessmentSave = function () {
        //post back to the server and update the assessment details    
        var options = {
            target: '',
            url: '../Referral/UpdateReferralAssessmentDetails',
            data: { ReferralId: referralIdentifier },
            beforeSubmit: othis.ValidateReferralAssessmentSubmission,
            dataType: 'json',
            success: othis.UpdateReferralAssessmentStatus,
            clearForm: true
        };

        $('#uxReferralAssessmentDetailsForm').ajaxSubmit(options);

    }

如果你插入一个；在每个函数的末尾，如下所示：

this.SetupValidations = function() {
            //validations
            LLNP4.validate('#uxReferralAssessmentDetailsForm',
                {
            rules: {
                assessmentDecision: { requiredSelect: "0" },
                NoShowDate: { required: othis.clientDidNotShowValidation },
                DeclinedReason: { requiredSelect: othis.clientDeclinedValidation }
                    }
                });
            };

有打字错误吗

othis.SetupValidations();

这不是取而代之的吗？

谢谢。试过了，这可能是一个很好的标准。很遗憾，我什么也没做。谢谢。否我使othis成为类似构造函数referralEdit{var decision；var othis=this；}
