来自 Firefox 的 jQuery 1.10.2 警告问题 [英] jQuery 1.10.2 warning issue from Firefox

问题描述

我尝试在我的网站上使用最新的 jQuery，但我从 Firefox 24 收到此警告标志和消息.

I tried to use latest jQuery for my website and I get this warning sign and message from Firefox 24.

警告:不推荐使用 getPreventDefault().改用 defaultPrevented.

Warning: Use of getPreventDefault() is deprecated. Use defaultPrevented instead.

留下那个问题可以吗?如何解决?

Is it fine to leave that problem? How to solve it?

推荐答案

这是一个已知问题，已在 1.10.2 版中报告，并已在 1.11/2.1 jQuery 里程碑中得到解决.在此处查看提议的拉取请求，以及关于错误跟踪器的报告此处.

This is a known issue, reported for version 1.10.2 and has been resolved for the 1.11/2.1 jQuery milestone. See a proposed pull request here, and the report on the bug tracker here.

要解决这个问题，只需使用更高版本的 jQuery，或者将 event.js 中的这一行从:

To fix this, just use a later version of jQuery, or change this line in event.js from:

this.isDefaultPrevented = ( src.defaultPrevented || src.getPreventDefault && src.getPreventDefault() ) ? returnTrue : returnFalse;

到这一行:

this.isDefaultPrevented = src.defaultPrevented ? returnTrue : returnFalse;

上面链接的拉取请求从未合并，尽管它确实解决了问题.该问题已通过此提交解决，如下所示:

The pull request linked above was never merged, although it did fix the problem. The issue was instead resolved by this commit and looks like this:

this.isDefaultPrevented = src.defaultPrevented || src.defaultPrevented === undefined && ( src.returnValue === false || src.getPreventDefault && src.getPreventDefault() ) ? returnTrue : returnFalse;
