HTML5图像拖动事件-ctrlKey在Firefox 29中仍然为false [英] HTML5 image drag event - ctrlKey remains false in Firefox 29

问题描述

这在Chrome浏览器中效果很好，但是我需要更改使其在Firefox中运行吗?

This works great in Chrome, but what do I need to change to make it work in Firefox?

e.ctrlKey在FF中仍然为假:

    console.log('ctrlKey', e.ctrlKey);
});

推荐答案

我认为这是Firefox中的错误.经过 Bugzilla 的挖掘，我发现了与标题为 DragEnd事件的问题类似的未确认错误不反映真实的ctrl/shift/alt键状态.

I think this is a bug in Firefox. After some digging in Bugzilla I found unconfirmed bug similar to your problem titled DragEnd event does not reflect real ctrl/shift/alt key status.
