A few of the more serious problems:

(一些较严重的问题：)

• document.write (henceforth DW) does not work in XHTML

  (document.write（此后称为DW）在XHTML中不起作用)

• DW does not directly modify the DOM, preventing further manipulation (trying to find evidence of this, but it's at best situational)

  ( DW不会直接修改DOM，从而阻止了进一步的操作 （试图寻找证据，但充其量只是视情况而定）)

• DW executed after the page has finished loading will overwrite the page, or write a new page, or not work

  (页面加载完成后执行的DW将覆盖页面，或写入新页面，或不起作用)

• DW executes where encountered: it cannot inject at a given node point

  (DW在遇到的地方执行：它无法在给定的节点上注入)

• DW is effectively writing serialised text which is not the way the DOM works conceptually, and is an easy way to create bugs (.innerHTML has the same problem)

  (DW有效地编写了序列化的文本，这不是DOM在概念上的工作方式，并且是创建错误的简便方法（.innerHTML存在相同的问题）)

Far better to use the safe and DOM friendly DOM manipulation methods

(使用安全且对DOM友好的DOM操作方法要好得多)
