可以通过删除该行来删除404

//@ sourceMappingURL=jquery-1.10.2.min.map

从jQuery文件的顶部。

jQuery文件的顶部看起来像这样。

/*! jQuery v1.10.2 | (c) 2005, 2013 jQuery Foundation, Inc. | jquery.org/license
//@ sourceMappingURL=jquery-1.10.2.min.map
*/

把它改成

/*! jQuery v1.10.2 | (c) 2005, 2013 jQuery Foundation, Inc. | jquery.org/license */

源映射的目的

Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location. Developer tools (currently WebKit nightly builds, Google Chrome, or Firefox 23+) can parse the source map automatically and make it appear as though you're running unminified and uncombined files.

如果你想获得不同版本的源地图文件，可以使用这个链接 http://code.jquery.com/jquery-x.xx.x.min.map

相反，x.xx.x输入您的版本号。

注意:一些链接，你得到这个方法，可能是坏的:)

在遵循其他答案中的说明后，我需要从地图文件中剥离这个版本，以便为我工作。

例如:重命名

jquery-1.9.1.min.map

to

jquery.min.map

下载地图文件和jQuery的非压缩版本。 把它们和缩小版放在一起: 包括缩小版本到你的HTML: 登录谷歌Chrome浏览器: 阅读JavaScript源映射介绍 熟悉调试JavaScript

jQuery的新版本需要这个文件http://code.jquery.com/jquery-1.10.2.min.map

此文件的可用性描述在http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/

更新:

jQuery 1.11.0/2.1.0

// sourceMappingURL注释不包含在压缩文件中。
