XMLHttpRequest.status
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
只读属性 XMLHttpRequest.status
返回了 XMLHttpRequest
响应中的数字状态码。status
的值是一个无符号短整型
。在请求完成前,status
的值为 0
。值得注意的是,如果 XMLHttpRequest 出错,浏览器返回的 status 也为 0。status 码是标准的 HTTP status codes。举个例子,status
200
代表一个成功的请求。如果服务器响应中没有明确指定 status 码,XMLHttpRequest.status
将会默认为 200
。
例子
js
var xhr = new XMLHttpRequest();
console.log("UNSENT", xhr.status);
xhr.open("GET", "/server", true);
console.log("OPENED", xhr.status);
xhr.onprogress = function () {
console.log("LOADING", xhr.status);
};
xhr.onload = function () {
console.log("DONE", xhr.status);
};
xhr.send(null);
/**
* 输出如下:
*
* UNSENT(未发送)0
* OPENED(已打开)0
* LOADING(载入中)200
* DONE(完成)200
*/
