However, if you're using lodash, then I like cs01's answer from that post:
但是，如果您使用的是 lodash，那么我喜欢该帖子中 cs01 的回答：
_.escape('fred, barney, & pebbles');
// => 'fred, barney, & pebbles'

This is old, but my favorite way to do it is to let the browser figure it out:
这是旧的，但我最喜欢的方法是让浏览器弄清楚：
function encodeXML(data){
var d = document.createElement('div');
d.appendChild(document.createTextNode(data));
return d.innerHTML;
}
encodeXML('&');
Output:
输出：
"&"
“&”
You could also use d.innerText = data;or d.textContent = data;, but createTextNode()has the most browser support.
您也可以使用d.innerText = data;或d.textContent = data;，但createTextNode()拥有最多的浏览器支持。

Those are the only characters you need to worry about.
这些是您唯一需要担心的字符。
Generally you should be using a DOM interface to build XML documents then you don't need to worry about manually escaping things. That only becomes an issue if you are mashing together strings to build the XML.
通常，您应该使用 DOM 接口来构建 XML 文档，然后您无需担心手动转义。如果您将字符串混搭在一起以构建 XML，那只会成为一个问题。
