Are you missing urlin $.ajaxlike the one below
是否缺少url在$.ajax类似下面
$.ajax({
url: "/path to page",
statusCode: {
500: function() {
alert(" 500 data still loading");
console.log('500 ');
}
}
});

Dispite the accepted answer mentioned by @Danny, you can also do this in newer versions of jQuery.
尽管@Danny 提到了已接受的答案，但您也可以在较新版本的 jQuery 中执行此操作。
var xhr = $.ajax({
url: "somewhere"
});
xhr.fail(function(xhr, textStatus, error) {
// Error handling stuff here ...
});
See Deferred Object.
请参阅延迟对象。

}
});
