Question

这是代码：https://jsfiddle.net/magicschoolbusdropout/dwbmo3aj/18/

目前，我的代码允许我点击一个按钮，内容打开，点击内容关闭的同一个按钮。然后我点击第二个按钮，内容打开，点击相同的按钮内容关闭。我可以从第二个按钮切换到第一个按钮，但内容会附加。

我想做的是：在两个按钮之间切换。单击第一个按钮，然后单击第二个按钮，信息不会附加或移动。将不胜感激和所有帮助！谢谢:)

这些是我尝试切换的功能：

function currentOrder(){
  var current = document.getElementById("current");
  if (current.style.display === "none") {
    current.style.display = "block";  
  } else {
    current.style.display = "none";
  }
}

function orderHistory(){
  var history = document.getElementById("history");
  if (history.style.display === "none") {
    history.style.display = "block";
  } else {
    history.style.display = "none";
  }
}

Answer 1

只需将赋值移到函数之外。

这应该有效：

let current = document.getElementById("current");
let history = document.getElementById("history");

function currentOrder(){
    current.style.display = "block";
    history.style.display = "none"
}

function orderHistory(){
    current.style.display = "none";
    history.style.display = "block"
}

您无需检查当前状态，只需切换样式即可。保持简单……（亲吻）。
