如果时间到达所需时间，如何启用/禁用该按钮？

<button id="myButton" disabled>点击我</button>

// 获取按钮元素的引用
var myButton = document.getElementById("myButton");

// 启用按钮
myButton.disabled = false;

// 禁用按钮
myButton.disabled = true;

setTimeout(function() {
  myButton.disabled = false;
}, 5000);

var inputField = document.getElementById("myInput");

inputField.addEventListener("input", function() {
  if (inputField.value === "") {
    myButton.disabled = true;
  } else {
    myButton.disabled = false;
  }
});
