document.write not working in html
提问by oshai
I am try to write inside html document. this is my javascript code:
我尝试在 html 文档中写入。这是我的 javascript 代码：
<script type="text/javascript">document.write("Hello World!")</script>
I am working with chrome and get the following error:
我正在使用 chrome 并收到以下错误：
Uncaught TypeError: Object # has no method 'write'
未捕获的类型错误：对象 # 没有方法“写入”
I tried alertmethod and it worked.
我尝试了alert方法，它奏效了。
EDIT: this is part of a project in scala/lift that also uses jquery if that may hint something. I suspect document object is redefined. is there a way to know that / to access the original one?
编辑：这是 scala/lift 中的一个项目的一部分，如果这可能暗示某些事情，它也使用 jquery。我怀疑文档对象被重新定义。有没有办法知道/访问原始的？

I had a similar problem, trying to embed the google maps api in my lift application. The script also uses document.write to load external libraries. The Google Chrome console stated that there is no function document.write.
我有一个类似的问题，试图在我的电梯应用程序中嵌入谷歌地图 api。该脚本还使用 document.write 加载外部库。谷歌浏览器控制台声明没有函数document.write。
The problem seems to be that XHTML does not allow document.write. ( http://www.w3.org/MarkUp/2004/xhtml-faq#docwrite) A solution could be to change the mime/type of your documents, e.g. by adding the following line to your Boot.scala
问题似乎是 XHTML 不允许 document.write。( http://www.w3.org/MarkUp/2004/xhtml-faq#docwrite) 解决方案可能是更改文档的 mime/type，例如通过将以下行添加到 Boot.scala
LiftRules.useXhtmlMimeType = false
LiftRules.useXhtmlMimeType = false

I am not sure why this happened, maybe its related to the phase the page load was on. as a workaround I added a div with id hellowworlddivand the following worked:
我不确定为什么会发生这种情况，可能与页面加载所处的阶段有关。作为一种解决方法，我添加了一个带有 id 的 divhellowworlddiv并且以下操作有效：
<script type="text/javascript">document.getElementById("hellowworlddiv").innerHTML = "Hello World!"</script>
