Firefox Gecko SDK：NPP_GetValue 没有被调用
我在
它与 Firefox 3.6 完美配合。
按照上述步骤，我创建了一个新的脚本插件（npmyplugin.dll）。我当前将 npmyplugin.dll 放置在 Firefox/plugins 以外的文件夹中。我正在注册表中注册关联的 mime 类型和插件路径。插件已正确加载。但现在浏览器没有调用NPP_GetValue。
我怀疑这一定是因为我将插件放在 Firefox/plugins 以外的目录中。因此，我对 npruntime.dll （Gecko sdk 附带的示例）做了同样的事情。令人惊讶的是，npruntime.dll 脚本正在运行。请指导我在创建新插件时是否遗漏了任何重要的内容。
I have tried out the NPRuntime sample provided with the Gecko SDK 1.9.1 with the help of this link.
It works perfectly fine with Firefox 3.6.
Following the above steps I created a new scripting plugin (npmyplugin.dll). I am currently placing npmyplugin.dll in a folder other than Firefox/plugins. I am registering the associated mime-type and plugin path in the registry. The plugin gets loaded properly. But now the browser is not calling NPP_GetValue.
I was suspecting that it must be because I am placing the plugin in a directory other than Firefox/plugins. Hence I did the same with npruntime.dll (the sample which comes with Gecko sdk). Suprisingly npruntime.dll scripting was working. Please guide me whether I missing anything important while creating the new plugin.

在许多情况下，直到您第一次使用 javascript 访问 NPObject 时，才会调用 NPP_GetValue 来获取它。当您执行 getElementById 时，它将进行调用。
可能正在对 GetValue 进行其他调用，但您看不到它们，因为您没有处理它们。然而，这仍然不能保证。
NPP_GetValue doesn't get called to get the NPObject until the first time you access it with javascript in many cases. When you do a getElementById, it will make the call.
Likely other calls to GetValue are being made, but you aren't seeing them because you aren't handling them. However, that's still not guaranteed.
抱歉这么晚才回复。我以某种方式解决了这个问题。我正在使用标签嵌入插件
然后我写了一小段javascript代码
var MyWorkingPlugin = document.getElementById('MyPlugin');
似乎在执行上面的javascript之后调用了NPP_GetValue。目前我还没有令人信服的理由为什么会发生这种情况，但它确实有效，我现在很高兴。如果有人可以解释上述行为，请告诉我们。
Sorry for replying so late. I somehow solved the problem. I was embedding the plugin using tag
then i wrote a small javascript code
var MyWorkingPlugin = document.getElementById('MyPlugin');
It seems that after executing the above javascript NPP_GetValue was called. Currently I have no convincing reason why it happened but it worked and I am happy for the moment. If anyone can explain the above behaviour please let us know.
