改起来应该不难
下面只是检测是否包含@的。
/**************************************************************************
名称： 校验是否为合法email
**************************************************************************/
function isEmailAddr(str)
{
str = trim( str );
int i;
int j; i = str.indexOf("@");
j = str.indexOf(".");
if(i != -1 && j != -1 && i<j)
return true;
}
看来我孤陋寡闻，跟不上形势发展，落后啦，呵呵
