正如@criz已经提到的，在循环中构建DOM是一种非常糟糕的做法。创建documentFragment并将其附加到DOM会好得多。请查看 https://developer.mozilla.org/ en-US / docs / Web / API / Document / createDocumentFragment 有一个例子。

As @criz already mentioned, building DOM in a loop is a very bad practice. It's much better to create documentFragment and attach it to the DOM. Take a look at the https://developer.mozilla.org/en-US/docs/Web/API/Document/createDocumentFragment There is an example.
