onClick问题的多个功能

Question

您好，我有一个已简化的 onclick 按钮方案。我有两个 canvasses（一个正方形和一个圆圈）和一个 onclick。单击onclick时...

1)方块canvas'饱和度应该在3秒后增加5%

2) 3秒后打开模态对话框，里面有一个onclick

当按下 "modal dialog" onclick 时，它会关闭并清除并在旧圆之上重新绘制一个新圆 canvas。

理想情况下，当黄色方块的饱和度为 25%（或按下按钮 5 次）时，研究场景应该完成并将我发送到 404。但是方块 canvas不会增加它的饱和度，我不知道它是否会将我发送到 404，因为它不会增加到 25%。

但是 none 这在我的代码中有效。谁能帮忙。如有任何问题，请随时提出。

var squaretime = document.getElementById("timeCanvas");
  var sqt= squaretime.getContext("2d");
  sqt.globalAlpha = 0.1;
  sqt.beginPath();
  sqt.rect(0, 0, 80, 80);
  sqt.fillStyle = "yellow";
  //cir.globalAlpha = 0.4;
  sqt.fill();
  sqt.stroke();

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.beginPath();
ctx.arc(300, 300, 250, 0, 2 * Math.PI);
ctx.stroke();

ctx.beginPath();
ctx.moveTo(125,125);
ctx.lineTo(475,475);
ctx.stroke();
ctx.beginPath();

ctx.moveTo(125,475);
ctx.lineTo(475, 125);
ctx.stroke();


var modal = document.querySelector(".modal");
var trigger = document.querySelector(".trigger");
var closeButton = document.querySelector(".close-button");


function toggleModal() {
    setTimeout(function() {
        modal.classList.toggle("show-modal");
    }, 3000)
}

function closeModalNow() {
  modal.classList.toggle("show-modal");
  document.querySelector('input[name="conf1d3nce"]').value = null;

var canvas = document.getElementById("myCanvas");
var ctx = canvas.getContext("2d");
ctx.clearRect(0, 0, 600, 600);

ctx.beginPath();
ctx.moveTo(125,125);
ctx.lineTo(475,475);
ctx.stroke();
ctx.beginPath();

ctx.moveTo(125,475);
ctx.lineTo(475, 125);
ctx.stroke();
}

trigger.addEventListener("click", toggleModal);
closeButton.addEventListener("click", closeModalNow);
