验证汇总

常用验证汇总表

贡献规则：

• 保证添加内容可以，复制后直接运行
• 尽量详细的添加一些实现原理说明

字符验证集合

检查是否checkbox|radio

var checkable = function(element) {
	return /radio|checkbox/i.test(element.type);
};

为空验证

function required(elem, value){
	if (elem.nodeName.toLowerCase() === 'select') {
	    var v = elem.value;
	    return v && v != 0 && v != '';
	}
	if (checkable(elem)) {
	    return getLength(value, elem) > 0;
	}
	return value.length > 0;
}

国内邮政编码

/^[1-9][0-9]{5}$/.test(value)

手机号验证

TODO: 手机号如果增加新的号段，需要手动更新

/^(13|15|18|14|17)\d{9}$/.test(value)

邮箱验证

/^([a-zA-Z0-9_\.\-+])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/.test(value)

IPv4

/^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/.test(value)

url

/^((http|https):\/\/(\w+:{0,1}\w*@)?(\S+)|)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?$/.test(value)

HTML标签

/<(.*)>.*<\/>|<(.*) \/>/.test(value)

身份证

身份证15位编码规则：dddddd yymmdd xx p
dddddd：地区码
yymmdd: 出生年月日
xx: 顺序类编码，无法确定
p: 性别，奇数为男，偶数为女
身份证18位编码规则：dddddd yyyymmdd xxx y
dddddd：地区码
yyyymmdd: 出生年月日
xxx:顺序类编码，无法确定，奇数为男，偶数为女
y: 校验码，该位数值可通过前17位计算获得
