GM_log和其他GM功能在Greasemonkey脚本中不起作用 [英] GM_log and other GM functions don't work in Greasemonkey scripts

问题描述

我在Firefox中创建了一个"Hello World" Greasemonkey脚本，该脚本只包含一行代码:

GM_log("Hello World");

这似乎没有作用，至少在我的Firebug控制台中没有产生任何输出.
与其他GM _...函数一样，例如GM_wait

当我更换时:

GM_log("Hello World");

具有:

alert("Hello World")

它起作用了(所以脚本标题不是问题).

我还将以下about:config选项设置为true:

• javascript.options.showInConsole
• extensions.firebug.showChromeErrors
• extensions.firebug.showChromeMessages

是否需要更改其他设置以使GM _...函数在Greasemonkey脚本中工作?

我是否必须更改其他GM_log消息的Firebug设置才能在Firebug控制台中显示?

解决方案

原因是在GM 1.0中添加了新的特殊元数据块命令: @grant . 如果需要GM_log起作用，则必须将此行添加到脚本元数据块中: "// @grant GM_log" ，否则它将无法正常工作. 您可以在 http://wiki.greasespot.net/@grant 中了解此功能.. >

I have created a "Hello World" Greasemonkey script in Firefox which contains only one line of code:

GM_log("Hello World");

This did not seem to function, at least it did not produce any output in my firebug console.
The same with other GM_... functions like GM_wait

When I replaced:

GM_log("Hello World");

with:

alert("Hello World")

it worked (so the script headers are not the problem).

I have also set the following about:config options to true:

• javascript.options.showInConsole
• extensions.firebug.showChromeErrors
• extensions.firebug.showChromeMessages

Is there some other setting to change for GM_... functions to work in Greasemonkey scripts?

Do I have to change other firebug settings for GM_log messages to show in the firebug console?

解决方案

The reason for this is a new special Metadata Block imperative: @grant, added in GM 1.0. If you need GM_log to work, you have to add this line into your script Metadata Block: "// @grant GM_log" , otherwise it will not work. You can read about this feature at http://wiki.greasespot.net/@grant.
