当input输入了空格是不会提示信息的

一般会去除空格然后进行验证

这个时候就要添加onkeyup事件去除左侧的空格

• 验证只输入空格通过验证

//添加验证手机方法        jQuery.validator.addMethod("isMobile", function(value, element) {            var length = value.length;            var mobile = /^(((13[0-9]{1})|(15[0-9]{1}))+\d{8})$/;            return this.optional(element) || (length == 11 && mobile.test(value));        }, "请正确填写您的手机号码");        //表单验证        $("#enterpriseAuth").validate({            debug: true,            onkeyup: function(element, event) {                //去除左侧空格                var value = this.elementValue(element).replace(/^\s+/g, "");                $(element).val(value);            },            errorClass: 'errMsg',            errorElement: "div",            errorPlacement: function(error, element) {                error.appendTo(element.parent());            },            groups: {                distpicker: "province city district"            },            rules: {                enterpriseName: {                    required: true                },                managerPhone: "isMobile",                managerEmail: {                    email: true,                },                province: "required",                city: "required",                district: "required"            },            messages: {                enterpriseName: {                    required: "请填写企业名称",                },                enterpriseAddress: {                    required: "请填写公司注册地址",                },                enterpriseContact: {                    required: "请填写街道详细地址",                },                managerName: {                    required: "请填写管理者姓名",                },                managerEmail: {                    required: "请填写管理者邮箱",                    email: "请填写正确邮箱格式"                },                managerPhone: {                    required: "请输入手机号",                    isMobile: "请填写正确手机号"                },                province: {                    required: "请选择省市区",                },                city: {                    required: "请选择省市区",                },                district: {                    required: "请选择省市区",                }            }        });
