jQuery Validate无法调用undefined的方法'call'

Question

这个错误让我疯狂,一切似乎都井井有条,但希望我错过了一些简单的事情.

我的aspx中的代码

        $('#myForm').validate({
            rules: {
                'ctl00$SecondaryPlaceHolder$txPayloadDate': {
                    required: true,
                    date: true
                },
                'ctl00$SecondaryPlaceHolder$ddlMapPlat': {
                    required: true
                },
                'ctl00$SecondaryPlaceHolder$txtBlock': {
                    maxLength: 3
                },
                'ctl00$SecondaryPlaceHolder$txtLeakNumber': {
                    number: true,
                    maxLength: 27
                },
                'ctl00$SecondaryPlaceHolder$txtHouseNumber': {
                    required: true,
                    maxLength: 10,
                },
                'ctl00$SecondaryPlaceHolder$txtStreet': {
                    required: true,
                    maxLength: 100
                },
                'ctl00$SecondaryPlaceHolder$txtCity': {
                    required: true,
                    maxLength: 50
                },
                'ctl00$SecondaryPlaceHolder$txtReading': {
                    isPositiveInteger: true,
                    maxLength: 100
                },
                'ctl00$SecondaryPlaceHolder$ddlInfoCodes': {
                    existsWithLowReading: true
                },
                'ctl00$SecondaryPlaceHolder$txtLocationRemarks': {
                    maxLength: 500
                },
                'txtGrade2RequestedRepairDate': {
                    date: true
                },
                'ctl00$SecondaryPlaceHolder$ddlEquipment': {
                    required: true
                }
            }
        });

自定义验证

$.validator.addMethod("isPositiveInteger",
    function (value, element) {
        if($.trim(value) !== '')
            return /^\d+$/.test(value);
        return true;
    },
    "Must be a valid integer."
);


$.validator.addMethod("existsWithLowReading",
    function (value, element) {
        if (parseFloat($('#SecondaryPlaceHolder_txtReading').val() <= 2) && value.length < 1) {
            return false;
        }
        return true;
    },
    "Info Code required if Reading % is less than three."
);

基本上问题是在自定义验证之外,但我还是把它们扔到了这里...提交时表单验证正常,但是有一些'门牌号'和'街道'在尝试填写它们时会抛出此错误在.

例如,我提交一个空的街道号码表格,验证工作,但当我填写输入时,模糊这个错误被抛出.

错误是在jquery.validate这里的var rule = { method: method, parameters: rules[method] }行:

 check: function (element) {
            element = this.validationTargetFor(this.clean(element));

            var rules = $(element).rules();
            var dependencyMismatch = false;
            var val = this.elementValue(element);
            var result;

            for (var method in rules) {
                var rule = { method: method, parameters: rules[method] };
                try {

                    result = $.validator.methods[method].call(this, val, element, rule.parameters);

                    // if a method indicates that the field is optional and therefore valid,
                    // don't mark it as valid when there are no other rules
                    if (result === "dependency-mismatch") {
                        dependencyMismatch = true;
                        continue;
                    }
                    dependencyMismatch = false;

                    if (result === "pending") {
                        this.toHide = this.toHide.not(this.errorsFor(element));
                        return;
                    }

                    if (!result) {
                        this.formatAndAdd(element, rule);
                        return false;
                    }
                } catch (e) {
                    if (this.settings.debug && window.console) {
                        console.log("exception occured when checking element " + element.id + ", check the '" + rule.method + "' method", e);
                    }
                    throw e;
                }
            }

提前感谢任何指针

我这方面的愚蠢错字是罪魁祸首

maxLength不是骆驼套装,应该是maxlength

虽然相同的东西是骆驼套装......似乎不一致,但很高兴我弄清楚了
