Email地址的格式验证规则

JS代码格式： 

var pattern = /\w[-\w.+]*@([A-Za-z0-9][-A-Za-z0-9]+\.)+[A-Za-z]{2,14}/;
var str = "xindd123456@163.com";
console.log(pattern.test(str));

Java代码格式： 

import java.util.regex.Matcher;
import java.util.regex.Pattern;public class RegexMatches {public static void main(String args[]) {String str = "xindd123456@163.com";String pattern = "\\w[-\\w.+]*@([A-Za-z0-9][-A-Za-z0-9]+\\.)+[A-Za-z]{2,14}";Pattern r = Pattern.compile(pattern);Matcher m = r.matcher(str);System.out.println(m.matches());}}

不能输入！@#￥%……&* 这种字符的正则表达式书写：

//邮箱格式验证
function checkEmail(email){var emailReg = /[@#\$%\^&\*]+/g;if (email!=null && email!='' && emailReg.test(email) == true) {alert("邮箱格式不正确！");return false;} else {return true;}
}
