你好, 请问如何判断下面输入的账号是邮箱地址啊?

加了这段好像不行啊
indexOf,o要大写
function testCount(){
var count1 = document.getElementById("txt_account").value;
var count2 = document.getElementById("txt_raccount").value; if(count1.indexOf('@163.com') <1)
{
alert("请输出网易通行证账号!");
return false;
}
if(count1!=count2){
alert("输入的账号不一致,请重新输入");
}else{
with(document.getElementById("form1")){
method="post";
action="zhongzhuan.asp";
submit();
}
}
}
