javascript - 如何在 Javascript 中创建每个变量中具有不同值的数组？

Question

不确定这个问题是否很好地解释了它，但我想将这些 Tone.JS 过滤器放在一个数组中。问题是它们都有不同的频率和增益值，最终也会有不同的 Q 值。

在下面查看我的代码，让我知道这是否可行。任何帮助表示赞赏，谢谢！

var noise = new Tone.Noise();

for (counter = 0; counter < 6; counter+=1) {
  var hipass[counter] = new Tone.Filter();
}

for (counter = 0; counter < 6; counter+=1) {
  var lowpass[counter] = new Tone.Filter();
}

var hipass1 = new Tone.Filter(8, "highpass", -12, -77.8);
var hipass2 = new Tone.Filter(16, "highpass", -12, -56.7);
var hipass3 = new Tone.Filter(31.5, "highpass", -12, -39.4);
var hipass4 = new Tone.Filter(63, "highpass", -12, -26.2);
var hipass5 = new Tone.Filter(125, "highpass", -12, -16.1);
var hipass6 = new Tone.Filter(250, "highpass", -12, -8.6);

var lowpass1 = new Tone.Filter(500, "lowpass", -12, -3.2);
var lowpass2 = new Tone.Filter(1000, "lowpass", -12);
var lowpass3 = new Tone.Filter(2000, "lowpass", -12, 1.2);
var lowpass4 = new Tone.Filter(4000, "lowpass", -12, 1.0);
var lowpass5 = new Tone.Filter(8000, "lowpass", -12, -1.1);
var lowpass6 = new Tone.Filter(1200, "lowpass", -12, -6.6);

noise.chain(hipass[counter], lowpass[counter], Tone.Master);
noise.volume = -20;
noise.stop();

使用 javascript 的.push()方法将新值附加到您的数组中：

var noise = new Tone.Noise();

var hipass[counter] = new Array();
var lowpass[counter] = new Array();

hipass.push(new Tone.Filter(8, "highpass", -12, -77.8));
hipass.push(new Tone.Filter(16, "highpass", -12, -56.7));
hipass.push(new Tone.Filter(31.5, "highpass", -12, -39.4));
hipass.push(new Tone.Filter(63, "highpass", -12, -26.2));
hipass.push(new Tone.Filter(125, "highpass", -12, -16.1));
hipass.push(new Tone.Filter(250, "highpass", -12, -8.6));

lowpass.push(new Tone.Filter(500, "lowpass", -12, -3.2));
lowpass.push(new Tone.Filter(1000, "lowpass", -12));
lowpass.push(new Tone.Filter(2000, "lowpass", -12, 1.2));
lowpass.push(new Tone.Filter(4000, "lowpass", -12, 1.0));
lowpass.push(new Tone.Filter(8000, "lowpass", -12, -1.1));
lowpass.push(new Tone.Filter(1200, "lowpass", -12, -6.6));

noise.chain(hipass[counter], lowpass[counter], Tone.Master);
noise.volume = -20;
noise.stop();
