有没有工具删除javascript中未使用的方法? [英] Is there a tool to remove unused methods in javascript?
问题描述
我收集了来自第三方的javascript文件集合,我想删除所有未使用的方法,以便将大小降低到更合理的水平。
I've got a collection of javascript files from a 3rd party, and I'd like to remove all the unused methods to get size down to a more reasonable level.
有没有人知道为Javascript执行此操作的工具?至少给出一个未使用/使用过的方法列表,这样我就可以进行手动修剪?除了运行像YUI Javascript压缩器工具之类的东西之外......
Does anyone know of a tool that does this for Javascript? At the very least give a list of unused/used methods, so I could do the manually trimming? This would be in addition to running something like the YUI Javascript compressor tool...
否则我的想法是编写一个perl脚本来尝试帮助我这样做。
Otherwise my thought is to write a perl script to attempt to help me do this.
推荐答案
不。因为你可以像疯狂动态一样使用这些方法。
No. Because you can "use" methods in insanely dynamic ways like this.
obj[prompt("Gimme a method name.")]();
