Logs the current value of a timer that was previously started by calling
console.time()
to the console.
见 计时器 in the documentation for details and examples.
注意： 此特征可用于 Web 工作者 .console.timeLog(label);
label
The name of the timer to log to the console.
If no label parameter included:
default: 1042ms
If an existing
label
is included:
If there is no running timer,
timeLog()
returns the warning:
console.time("answer time");
alert("Click to continue");
console.timeLog("answer time");
alert("Do a bunch of other stuff...");
console.timeEnd("answer time");
The output from the example above shows the time taken by the user to dismiss the first alert box, followed by the time it took for the user to dismiss the second alert:
Notice that the timer's name is displayed when the timer value is logged using
timeLog()
and again when it's stopped. In addition, the call to timeEnd() has the additional information, "timer ended" to make it obvious that the timer is no longer tracking time.
