从Greasemonkey调用时，jQuery UI对话框引发错误 [英] jQuery UI Dialog Throw Errors When Invoked from Greasemonkey

问题描述

每次尝试从
Greasemonkey创建一个对话框时，我都会收到这个尴尬的错误...我认为它与
XPCNativeWrapper https://developer.mozilla.org/en/XPCNativeWrapper#Limitations_of_XPCNativeWrapper
，虽然我不是100％确定。

I'm getting this awkward error any time I try and create a dialog from Greasemonkey... I believe it has to do with the limitations of XPCNativeWrapper https://developer.mozilla.org/en/XPCNativeWrapper#Limitations_of_XPCNativeWrapper , though I am not 100% sure.

我使用过的核心jQuery方法都没有导致错误
（追加，css，提交，keydown，每个......） 。

None of the core jQuery methods that I've used have caused errors (append, css, submit, keydown, each, ...).

这可能是Greasemonkey中的错误，或者由于
Greasemonkey和jquery ui之间的交互，但我真的是
有兴趣了解如何让他们一起工作。

It is possible that this could be an error in Greasemonkey or due to the interaction between Greasemonkey and jquery ui, but I am really interested in figuring out how to get them to work together.

$(document).ready(function() {

});

错误：

更新：标准jQuery库中的focus（）方法也会抛出相同的错误：

Update: The focus() method from the standard jQuery library also throws the same error:

$('body').focus();

也许UI在某个时候调用焦点方法？

Maybe the UI is calling the focus method at some point?

任何帮助都将不胜感激！

Any help will be greatly appreciated!

推荐答案

这个线程很老但是使用Greasemonkey的方法Jquery to focus（）是向jquery对象添加[0]以将其转回DOM元素。

This thread is pretty old but the way to use Greasemonkey with Jquery to focus() is to add a [0] to the jquery object to turn it back to a DOM element.

      //Example:  
      $('#obj').focus();                          //Does not work
      document.getElementById('obj').focus();     //Works

      //Hybrid:
      $(#obj)[0].focus();                         //Work around
