javascript - JSLint "document.write can be a form of eval"- 这是怎么回事？

Question

我在 JSLint 中看到过这条消息...

document.write can be a form of eval.

并想知道到底是怎么回事？

JSLint instructions页面状态:

The eval function...provide access to the JavaScript compiler. This is sometimes necessary, but in most cases it indicates the presence of extremely bad coding....

那么，document.write 如何“提供对 JavaScript 编译器的访问”呢？

谢谢

你的浏览器用这个做什么？

document.write('<script type="text/javascript">window.alert("evaled " + (1 + 2))</script>');
