XMLHttpRequest.responseText

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.

XMLHttpRequest.responseText 在一个请求被发送后,从服务器端返回文本。

语法

var resultText = XMLHttpRequest.responseText;

取值

DOMStringXMLHttpRequest 返回的纯文本的值。当 DOMStringnull 时,表示请求失败了。当DOMString 为 "" 时,表示这个请求还没有被 send()

当处理一个异步 request 的时候,尽管当前请求并没有结束,responseText 的返回值是当前从后端收到的内容。

当请求状态 readyState 变为 XMLHttpRequest.DONE (4),且 status 值为 200("OK")时,responseText 是全部后端的返回数据

例子

js
var xhr = new XMLHttpRequest();
xhr.open("GET", "/server", true);

// If specified, responseType must be empty string or "text"
xhr.responseType = "text";

xhr.onload = function () {
  if (xhr.readyState === xhr.DONE) {
    if (xhr.status === 200) {
      console.log(xhr.response);
      console.log(xhr.responseText);
    }
  }
};

xhr.send(null);
