PHP代码改成JS代码

Question

$servername = trim($_SERVER['SERVER_NAME']);
$verifyurl = file_get_contents('http://localhost/token.php?domain='.$servername);
if(!empty($verifyurl)){
}else{
die("没有找到！");
}

如何把这段PHP代码改为JS代码，想加在JS里面

Answer 1

不过javascript跨域设置很麻烦

$.ajax({ 
data:{domain:window.location.hostname},  
 dataType: "txt",
 type: "get",
 url: "http://localhost/token.php",
success: function(data){ 
if(data==''){

}else{
alert("没有找到！")
}
});
