跨平台，跨浏览器的Javascript性能分析

Question

In addition to my recent question on server-side profiling of a PHP app, an app can have a ton of javascript, being all AJAXy in content.

This begs the question of cross-platform, cross-browser javascript profiling tools - do they exist, what ones do people use, and what benefits are there for each one?

Much appreciated.

Answer 3

Check out HTML 5 Boilerplate .

It includes a Javascript profiler that works for IE6/7 as well. Watch the video on further explanation on how to do this. There are lots of other neat stuff in there too related to latest web standards/practices.

Answer 4

如果您的代码抽象得很好，使用良好的跨浏览器框架和库，并避免在任何可能的情况下使用本机JavaScript，您不必担心有工具来帮助您跨所有不同的浏览器进行测试。
