Retrieving the Post Request response and storing into a variable?
提问by Max
So I have the below code:
所以我有以下代码：
var formData = new FormData();
formData.append("title", document.getElementById("title").value);
formData.append("html",my_html);
var xhr = new XMLHttpRequest();
xhr.open("POST", "https://www.mywebsite.com/index");
xhr.send(formData);
xhr.onreadystatechange = function() {
// If the request completed, close the extension popup
if (req.readyState == 4)
if (req.status == 200) window.close();
};
The server is supposed to send back a response in JSON format. How do I retrieve and store that in a variable?
服务器应该以 JSON 格式发回响应。如何检索并将其存储在变量中？

If the answer is in JSON, you have the result in the responseText attribute.
如果答案是 JSON，则结果在 responseText 属性中。
if (xhr.readyState == 4)
if (xhr.status == 200)
var json_data = xhr.responseText;
For more details, view: XMLHttpRequest

Your response is in xhr.responseText.
您的回复在xhr.responseText.

Just use xhr.responseTextto get the response of the request. You can also use xhr.responseXMLto retreive a DOM-compatible document object of the response, that means you can access it like document.
仅用于xhr.responseText获取请求的响应。您还可以使用xhr.responseXML检索响应的 DOM 兼容文档对象，这意味着您可以像document.
