javascript - Vanilla javascript : Get a specific element of page in an ajax get request

Question

我正在尝试从另一个页面获取 #test1 并将其附加到主页的 #test3。这是我到目前为止所做的:

<div id="test3"></div>

var request = new XMLHttpRequest();
request.open('GET', '//jsbin.com/wemowe', true);

request.onload = function() {
  if (request.status >= 200 && request.status < 400) {
    var resp = request.responseText;  
    var parser = new DOMParser();
    var xmlDoc = parser.parseFromString(resp,"text/xml");
    var tds = xmlDoc.getElementById("test1");
    console.log(xmlDoc);
    document.getElementById('test3').innerHTML=tds.innerHTML;
  } else {}
};

request.onerror = function() {};

request.send();

Here is JSBin

有什么建议可以让它发挥作用吗？

Answer 1

文档类型导致此处出现问题。

var xmlDoc=parser.parseFromString(resp, "text/xml");

将其更改为:

var xmlDoc=parser.parseFromString(resp, "text/html");
