非标
此特征是非标准的,且不在标准轨道中。不要在面向 Web 的生产站点中使用它:它不适用于每个用户。实现之间可能存在大的不兼容性,且行为将来可能改变。

Calling this API immediately after console.profile() can cause it to not work. To work around this, call it in a setTimeout with at least 5ms delay. See bug 1240249 .

The profileEnd method stops recording a profile previously started with Console.profile() .

You can optionally supply an argument to name the profile. Doing so enables you to stop only that profile if you have multiple profiles being recorded.

  • if Console.profileEnd() is passed a profile name, and it matches the name of a profile being recorded, then that profile is stopped.
  • if Console.profileEnd() is passed a profile name and it does not match the name of a profile being recorded, no changes will be made.
  • if Console.profileEnd() is not passed a profile name, the most recently started profile is stopped.
注意: 此特征可用于 Web 工作者 .
