我正在尝试验证用户在javascript中输入的电子邮件地址
var email = document.getElementById("<%=Email.ClientID%>").value;
// checks if the e-mail address is valid
var emailPat = /^[_a-z0-9-]+(\.[_a-z0-9-]+)*(\+[a-z0-9-]+)?@[a-z0-9-]+(\.[a-z0-9-]+)*$/i;
var matchArray = email.match(emailPat);
if (matchArray == null) {
alert("Not a valid e-mail address");
document.getElementById("<%=Email.ClientID%>").focus();
return false;
}
这很有用,可以验证电子邮件地址,但在此电子邮件地址返回false ayaz5+any+thing+you+want@gmail.com我想要的是这也是一个有效的电子邮件地址,我需要在此感谢中做出哪些更改

试试这段代码:
var email = 'ayaz5+any+thing+you+want@gmail.com';
var regex = /^([a-zA-Z0-9_.+-])+\@(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,4})+$/;
var matchArray = regex.test(email);
if (matchArray) {
alert("valid");
} else {
alert("Not a valid e-mail address");
}
