JavaScript警告在Firefox 6不工作 [英] JavaScript alert not working in Firefox 6

问题描述

我试着在Firefox 6运行在地址栏中输入该JavaScript code：

I tried running this JavaScript code in the address bar in Firefox 6:

javascript:alert("Hello")

我收到了

的ReferenceError：没有定义的警报

ReferenceError: alert not defined.

它曾经在Firefox 5做工精细，虽然，仍然工作在Opera，Safari和Chrome。我该如何解决这个问题？

It used to work fine in Firefox 5 though, and still works on Opera, Safari and Chrome. How do I fix this?

推荐答案

好像使用的javascript：和数据：网址（直接在地址栏）目前不允许按照此评论：

It seems using javascript: and data: URLs (directly in the address bar) are currently not allowed as per this comment:

通知你，我可能会到这个bug分割成多个，短期和长期修复。

FYI, I'm probably going to split this bug into multiple, short and longer term fixes.

短期：禁止JavaScript代码粘贴：网址到地址栏搜索
  从长期来看：另外需要在那个小书签被列入白名单
               书签管理器，才可以运行JavaScript

Short term: disallow pasting of javascript: URLs into the URL bar
Longer term: additionally require that bookmarklets be "whitelisted" in the Bookmark Manager before it can run JavaScript

和这是错误这是在的latest版本。该最后的评论还指出：

And this is the "bug" that was resolved in the latest version. The last comment also states:

JavaScript的：实际上并没有忽视 - 他们正在运行，但在没有任何通常的DOM方法，你所期望的，所以最常见的用途是空的情况下（如JavaScript的：警报（1））只是扔（从而有效地忽略）。 JavaScript的：1 + 1工作正常，但

javascript: is not actually ignored - they're run, but in an "empty" context that doesn't have any of the usual DOM methods you would expect, so most common uses (e.g. javascript:alert(1)) just throw (and thus are effectively ignored). javascript:1+1 works fine, though.

现在

我该如何解决这个问题？

How do I fix this?

您不能，你不得不等待，直到他们决定一个适当的解决方案。正如评论所说，小书签将工作，但必须明确允许的。如果你只是想测试code，使用萤火虫或新的便签功能。

You can't, you have to wait until they decided for a proper solution. As the comment said, bookmarklets will work, but must be explicitly allowed. If you just want to test code, use either Firebug or the new Scratchpad feature.
