XMLHttpRequest.statusText

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.statusText 返回了XMLHttpRequest 请求中由服务器返回的一个DOMString 类型的文本信息,这则信息中也包含了响应的数字状态码。不同于使用一个数字来指示的状态码XMLHTTPRequest.status,这个属性包含了返回状态对应的文本信息,例如"OK"或是"Not Found"。如果请求的状态readyState的值为"UNSENT"或者"OPENED",则这个属性的值将会是一个空字符串。如果服务器未明确指定一个状态文本信息,则statusText的值将会被自动赋值为"OK"。

例子

js
var xhr = new XMLHttpRequest();
console.log("0 UNSENT", xhr.statusText);

xhr.open("GET", "/server", true);
console.log("1 OPENED", xhr.statusText);

xhr.onprogress = function () {
  console.log("3 LOADING", xhr.statusText);
};

xhr.onload = function () {
  console.log("4 DONE", xhr.statusText);
};

xhr.send(null);

/**
 * 输出如下:
 *
 * 0 UNSENT
 * 1 OPENED
 * 3 LOADING OK
 * 4 DONE OK
 */
