Firefox has this annoying behavior that it let's the user drag and drop any image element by default. How can I cleanly disable this default behavior with jQuery?

推荐答案

下面将做在Firefox 3和更高版本：

The following will do it in Firefox 3 and later:

$(document).on("dragstart", function() {
     return false;
});

如果您想preFER不要禁用所有拖动（例如，你不妨仍然允许用户拖动链接到他们的链接工具栏），可以确保只有＆LT; IMG＆GT; 元素拖动是prevented：

If you would prefer not to disable all drags (e.g. you may wish to still allow users to drag links to their link toolbar), you could make sure only <img> element drags are prevented:

$(document).on("dragstart", function(e) {
     if (e.target.nodeName.toUpperCase() == "IMG") {
         return false;
     }
});

记住，这将使中的链接图像熊被拖动。

Bear in mind that this will allow images within links to be dragged.
