问题描述

嗨！

有没有办法将消息写入javascript控制台？就像一个

debug.write（）方法？

谢谢！

解决方案

如果你在谈论Mozilla / Firefox javascript控制台，那么在mozillazine上有一个很好的维基文档：

a：

http://kb.mozillazine.org/JavaScript_Console


看起来最简单的方法是这样做：

consoleService.logStringMessage（" Hello world！"）;
< blockquote class =post_quotes>有没有办法将消息写入javascript控制台？

Nathan，

谢谢。我无法解决这个问题。我得到了

获取属性的权限UnnamedClass.classes

我认为该服务适用于XUL应用程序。用JavaScript写入它有没有

方式？在JavaScript控制台本身中只有''消息

'的过滤器，因此它似乎想要写入

。

好的，Neil在
中提供答案 http：// groups -beta.google.com/group/...ef5e734f6f2123

var message =" Hello，world！";

setTimeout（message，0 ）;


，因为Hello，world！作为一个方法调用是不可解析的，这会得到

记录为错误[我得到''缺失;在陈述''之前，但是对于一个单词的消息，它可能会有所不同。

Hi!
Is there a way to write messages to the javascript console? Like a
debug.write() method?
Thanks!

解决方案

if you''re talking about the Mozilla/Firefox javascript console, there''s
a pretty good wiki document over at mozillazine:

http://kb.mozillazine.org/JavaScript_Console

looks like the easiest way is to do it like this:

consoleService.logStringMessage("Hello world!");

Is there a way to write messages to the javascript console?

Nathan,
Thanks. I couldn''t get that to work. I get
Permission denied to get property UnnamedClass.classes
I think that service is intended for XUL applications. Is there no
way to write to it with JavaScript? There''s a filter for ''messages
only'' in the JavaScript Console itself, so it seems to want to be
written to.

OK, Neil provides the answer in
http://groups-beta.google.com/group/...ef5e734f6f2123
var message = "Hello, world!";
setTimeout(message, 0);

since "Hello, world!" isn''t resolvable as a method call, this gets
logged as an error [I get ''Missing ; before statement'', but it would
probably be different for a single word message.]
