jQuery表单验证时，不出现提示信息

$(document).ready(function(){ /* 设置默认属性 */ $.validator.setDefaults({ submitHandler: function(form) { form.submit(); } }); // 中文字两个字节 jQuery.validator.addMethod("byteRangeLength", function(value, element, param) { var length = value.length; for(var i = 0; i < value.length; i++){ if(value.charCodeAt(i) > 127){ length++; } } return this.optional(element) || ( length >= param[0] && length <= param[1] ); }, "请确保输入的值在3-15个字节之间(一个中文字算2个字节)"); /* 追加自定义验证方法 */ // 身份证号码验证 jQuery.validator.addMethod("isIdCardNo", function(value, element) { return this.optional(element) || isIdCardNo(value); }, "请正确输入您的身份证号码"); // 字符验证 jQuery.validator.addMethod("userName", function(value, element) { alert(/^[a-zA-Z\u0391-\uFFE5]{2}[\u0391-\uFFE5\w]{0,14}$/ig.test(value)); return this.optional(element) || /^[a-zA-Z\u0391-\uFFE5]{2}[\u0391-\uFFE5\w]{0,14}$/ig.test(value); }, "用户名只能包括中文字、英文字母、数字和下划线"); // 手机号码验证 jQuery.validator.addMethod("isMobile", function(value, element) { var length = value.length; return this.optional(element) || (length == 11 && /^(((13[0-9]{1})|(15[0-9]{1}))+\d{8})$/.test(value)); }, "请正确填写您的手机号码"); // 电话号码验证 jQuery.validator.addMethod("isPhone", function(value, element) { var tel = /^(\d{3,4}-?)?\d{7,9}$/g; return this.optional(element) || (tel.test(value)); }, "请正确填写您的电话号码"); // 邮政编码验证 jQuery.validator.addMethod("isZipCode", function(value, element) { var tel = /^[0-9]{6}$/; return this.optional(element) || (tel.test(value)); }, "请正确填写您的邮政编码"); $("#regFrom").validate({ /* 设置验证规则 / rules: { userName: { required: true, userName: true, byteRangeLength: [3,15] }, password: { required: true, minlength: 5 }, repassword: { required: true, minlength: 5, equalTo: "#password" }, question: { required: true }, answer: { required: true }, realName: { required: true }, cardNumber: { isIdCardNo: true }, mobilePhone: { isMobile: true }, phone: { isPhone: true }, email: { required: true, email: true }, zipCode: { isZipCode:true } }, / 设置错误信息 */ messages: { userName: { required: "请填写用户名", userName:"请输入中文,英文", byteRangeLength: "用户名必须在3-15个字符之间(一个中文字算2个字符)" }, password: { required: "请填写密码", minlength: jQuery.format("输入{0}.") }, repassword: { required: "请填写确认密码", equalTo: "两次密码输入不相同" }, question: { required: "请填写您的密码提示问题" }, answer: { required: "请填写您的密码提示答案" }, realName: { required: "请填写您的真实姓名" }, email: { required: "请输入一个Email地址", email: "请输入一个有效的Email地址" } }, }); });

userName:

password:

repassword:

question:

answer:

realName:

eamil:

如果在IE里面报错的话就将这段 answer: {

required: "请填写您的密码提示答案"

},

realName: {

required: "请填写您的真实姓名"

},

email: {

required: "请输入一个Email地址",

email: "请输入一个有效的Email地址"

}

},

});
}); 最后一个地方的逗号去掉改为
required: "请填写您的密码提示答案"

},

realName: {

required: "请填写您的真实姓名"

},

email: {

required: "请输入一个Email地址",

email: "请输入一个有效的Email地址"

}

}

});
});
就行啦

/* 设置验证规则 */ 这个地方调用的是form的id 但是你的代码里面根本就不存在regFrom，将$("#regFrom") 改为$("#form")就可以
