这里是代码:https://jsfiddle.net/magicschoolbusdropout/dwbmo3aj/18/
目前，我的代码允许我单击一个按钮，内容打开，单击同一按钮，内容关闭。然后我单击第二个按钮，内容打开，单击同一按钮内容关闭。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:)
这些是我尝试在之间切换的功能:
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";
}
}

最佳答案
只需将分配移到函数之外即可。
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"
}
您不需要检查当前状态，只需切换样式即可。 保持简单......(亲吻)。
