javascript - 点击频率计算

Question

我正在尝试想出一种计算 Action 频率的方法，更具体地说，是鼠标点击。

这就是我的想法(我不是最好的数学或解释但我会尝试)。

我希望用户能够达到每秒 10 次点击的平均点击频率，并且我想知道每十分之一秒达到该目标的百分比。我快到了......我想但是因为我将鼠标点击设置回0，频率直接下降而不是逐渐下降......

这就是我现在的位置，但我现在还没有想清楚 :-)

var frequency = function( maxFrequency, milliseconds, callback ) {
    var mouseDown = 0;
    var loopCount = 1;
    var frequentTap = new taps( $(window), 'frequency', function() {
        mouseDown++;
    });
    var loop = setInterval( function() {
        callback( mouseDown / ( maxFrequency ) );
        if( loopCount % 10 === 0 ) mouseDown = 0;
        loopCount++;
    }, milliseconds );
    this.stop = function(){
        clearInterval( loop );
    }
};

frequency( 10, 100, function( freq ) {
    console.log(freq);
});

不要担心选项卡功能，只需假设它跟踪点击即可。

非常感谢任何帮助

我考虑的方式略有不同——您可以存储单击鼠标的时间戳，然后根据您存储的时间戳进行计算。

下面的可运行示例:

var frequency = function(maxFrequency, milliseconds, updateFrequency, callback ) {
  var timeTotal = 0;
  var clickTimes = [];
  var numberOfMilliseconds = milliseconds;

  document.addEventListener("click", function() {
    var currentTime = (new Date()).getTime(); //get time in ms

    //add the current time to the array and the counter
    timeTotal += currentTime;
    clickTimes.push(currentTime);
  });

  setInterval(function() {
    var currentTime = (new Date()).getTime(); //get time in ms

    //remove any items that occurred more than milliseconds limit ago
    while(clickTimes.length && (currentTime - clickTimes[0] > milliseconds)) {
      timeTotal -= clickTimes.shift();
    }

    if (clickTimes.length > 0) {
      numberOfMilliseconds = clickTimes[clickTimes.length - 1] - clickTimes[0];
    } else {
      numberOfMilliseconds = milliseconds;
    }

    callback(numberOfMilliseconds, clickTimes.length, (clickTimes.length * 100 / maxFrequency).toFixed(0)); 
  }, updateFrequency);
};

frequency(10, 1000, 100, function(milliseconds, numberOfClicks, targetPercentage) {
  document.getElementById("numberOfMilliseconds").innerHTML = milliseconds;
  document.getElementById("numberOfClicks").innerHTML = numberOfClicks;
  document.getElementById("targetPercentage").innerHTML = targetPercentage;
});

<h1>Click anywhere in the document</h1>
You've clicked <span id="numberOfClicks">0</span> times in the past <span id="numberOfMilliseconds">0</span> milliseconds<br/>
This is <span id="targetPercentage">0</span>% of your target.
