js校验真实姓名：regName =/^[u4e00-u9fa5]{2,4}$/
js校验身份证号码： regId = /(^d{15}$)|(^d{18}$)|(^d{17}(d|X|x)$)/
正整数正则：var posPattern = /^d+$/;
负浮点数正则：var negPattern = /^-d*.d+$/;
正数正则：var posPattern = /^d*.?d+$/;
数字正则：var numPattern = /^-?d*.?d+$/;
Email正则：var pattern = /^w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*$/;
最严谨的手机验证：
var mobile = /^(?:(?:+|00)86)?1(?:(?:3[d])|(?:4[5-7|9])|(?:5[0-3|5-9])|(?:6[5-7])|(?:7[0-8])|(?:8[d])|(?:9[1|8|9]))d{8}$/
中国手机号(宽松), 只要是13,14,15,16,17,18,19开头即可:
var mobile = /^(?:(?:+|00)86)?1[3-9]d{9}$/
最宽松的手机验证,只要是1开头即可, 如果你的手机号是用来接收短信, 优先建议选择这一条
var mobile = /^(?:(?:+|00)86)?1d{10}$/
数字/货币金额（支持负数、千分位分隔符）
var money=/(?:^[-]?[1-9]d{0,2}(?:$|(?:,d{3})*(?:$|(.d{1,2}$))))|(?:(?:^[0](.d{1,2})?)|(?:^[-][0].d{1,2}))$/
数字/货币金额 (只支持正数、不支持校验千分位分隔符)
/(?:^[1-9]([0-9]+)?(?:.[0-9]{1,2})?$)|(?:^(?:0){1}$)|(?:^[0-9].[0-9](?:[0-9])?$)/
