<script language="javascript">
function isEmail(strEmail) {
if (strEmail.search(/^\w+((-\w+)|(\.\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z0-9]+$/) != -1 && strEmail.search(chinamobile.com) != -1)
return true;
else
alert("Email格式不正确！");
document.formSignUp.email.value="";
document.formSignUp.email.focus();
}
</script>

function validateEmailFormat(str) {
// 常规校验
var format = /^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/;
if (!format.test(str)) {
return false;
}
// chinamobile.com校验
if (str.indexOf("@chinamobile.com") == -1) {
return false;
}
return true;
}
