推荐答案

没有，但是您可以使用JavaScript轻松定义它:

There isn't, but you can define it easily with JavaScript:

// console.time implementation for IE
if(window.console && typeof(window.console.time) == "undefined") {
    console.time = function(name, reset){
        if(!name) { return; }
        var time = new Date().getTime();
        if(!console.timeCounters) { console.timeCounters = {}; }
        var key = "KEY" + name.toString();
        if(!reset && console.timeCounters[key]) { return; }
            console.timeCounters[key] = time;
        };

    console.timeEnd = function(name){
        var time = new Date().getTime();
        if(!console.timeCounters) { return; }
        var key = "KEY" + name.toString();
        var timeCounter = console.timeCounters[key];
        var diff;
        if(timeCounter) {
            diff = time - timeCounter;
            var label = name + ": " + diff + "ms";
            console.info(label);
            delete console.timeCounters[key];
        }
        return diff;
    };
}

只需将其放入JS文件中，然后再使用console.time()和console.timeEnd().

Just place it in your JS file before you want to use console.time() and console.timeEnd().

这不是我的代码，实际上是我从Firebug核心复制的.

It is not my code, I actually copied it from Firebug core.
