jQuery validate验证扩展

jquery.validate.ext.js

// 身份证号码验证
jQuery.validator.addMethod("isIdCardNo", function(value, element) {

	return this.optional(element) || isIdCardNo(value);

	return this.optional(element) || (length == 11 && mobile.test(value));
}, "请正确填写您的手机号码");

// 长度等于验证
jQuery.validator.addMethod('lengthEq', function(value, element, param){
