回答by arnorhs
.success()only gets called if your webserver responds with a 200 OKHTTP header - basically when everything is fine.
.success()仅当您的网络服务器以200 OKHTTP 标头响应时才会被调用- 基本上当一切正常时。
However, .complete()will alwaysget called no matter if the ajax call was successful or not - maybe it outputted errors and returned an error - .complete() will still get called.
然而，.complete()将永远被调用无论Ajax调用是成功还是失败-也许它输出的错误，并返回一个错误- .complete（）仍然会被调用。
It's worth mentioning that .complete()will get called after.success()gets called - if it matters to you.
值得一提的是，它.complete()会在.success()被调用后被调用——如果这对你很重要的话。

success()is called when the server returns a 200 status code, complete()is called always when the request is complete, no matter the outcome.
success()在服务器返回 200 状态代码complete()时调用，在请求完成时始终调用，无论结果如何。

success()called when server return 200status code, complete()is called after success(). and i see some difference :
success()当服务器返回200状态码时complete()调用，在success(). 我看到了一些区别：
On success()you can't get xml response string that you get using $.ajax()and set dataType:xmlBut in complete()you can get string format of readed xml document using
在success()你不能得到你使用$.ajax()和设置的xml 响应字符串dataType:xml但是complete()你可以使用读取的 xml 文档的字符串格式
$.ajax({
url:'??',
dataType:'xml',
oncomplete: function(data,status){
console.log(data.responseText);
}
})

success()is called when the server returns success status code, like: 200, 201etc.
success()被称为当服务器返回success status code，如：200，201等等。
complete()is called always when the request is complete. (no matter, it is success/error response from server.)
complete()当请求完成时总是被调用。（无论如何，它是来自服务器的成功/错误响应。）
So,
所以，
- when there is
successresponse from server:complete()andsuccess()is called. - when there is
errorresponse from server:complete()anderror()is called.
- 当有
success来自服务器的响应时：complete()并被success()调用。 - 当有
error来自服务器的响应时：complete()并被error()调用。
For what purpose you can use complete(): suppose in beforeSend()you show a loader image, and in complete(), you can hide that loader image.
您可以出于什么目的使用complete()：假设在beforeSend()您显示 a loader image，而在 中complete()，您可以隐藏它loader image。
