恢復原始值只要新建一個類，設置一個默認樣式，到時候恢復成默認樣式就ok啦，顯示內容/隱藏內容可以編寫一個函數放在同一個函數里面，我的方法是這樣的：
function sh(){
var sst = getElementById("set");
if(sst.innerHTML=="隱藏內容"){
ost.style.display = none;
set.innerHTML = "顯示內容";
}
else{
ost.style.display = block;
set.innerHTML = "隱藏內容";
}
}
function sh(){
var sst = getElementById("set");
if(sst.innerHTML=="隱藏內容"){
ost.style.display = none;
set.innerHTML = "顯示內容";
}
else{
ost.style.display = block;
set.innerHTML = "隱藏內容";
}
}

需要在document.getElementById("con")后面加上.innerHTML輸出的結果才是JavaScript
