基于布尔值以编程方式更改按钮样式。未选中的项目应返回到原始样式

<button id="myButton">按钮</button>

#myButton {
  background-color: blue;
  color: white;
  font-size: 16px;
  padding: 10px 20px;
  border: none;
  cursor: pointer;
}

var button = document.getElementById("myButton");
var isSelected = false;

function toggleButtonStyle() {
  isSelected = !isSelected;
  
  if (isSelected) {
    button.style.backgroundColor = "red";
    button.style.color = "black";
    // 更改其他样式属性...
  } else {
    button.style.backgroundColor = "blue";
    button.style.color = "white";
    // 恢复原始样式...
  }
}

button.addEventListener("click", toggleButtonStyle);
