我試圖做一些基於文本的遊戲，但使用按鈕而不是文本輸入。例如，我想從一個頁面上的3個按鈕開始。當你選擇其中一個按鈕時，函數應該改變這個問題變量，然後爲下一個問題創建按鈕。按鈕，改變一個變量，並創建一個新的按鈕
問題一：
<DOCTYPE html>
<body>
<button onclick="russetPotato()">Russet</button>
<button onclick="redPotato()">Red</button>
<button onclick="sweetPotato()">Sweet</button>
</body>
<script type="text/javascript">
var seed = 0;
var soil = 0;
function russetPotato(){
seed = 1
document.write("You set seed as Russet Potato.");
}
function redPotato(){
seed = 2
document.write("You set seed as Red Potato.");
}
function sweetPotato(){
soil = 3
document.write("You set seed as Sweet Potato.");
}
</script>
</html>
現在我想要做的就是添加的第二個問題。在種子按鈕被回答後，我可以如何讓土壤按鈕出現，而不是同時出現？
<DOCTYPE html>
<body>
<button onclick="russetPotato()">Russet</button>
<button onclick="redPotato()">Red</button>
<button onclick="sweetPotato()">Sweet</button>
<button onclick="sandySoil()">Thin Sandy Soil</button>
<button onclick="loamSoil()">Loose Loam Soil</button>
<button onclick="claySoil()">Heavy Clay Soil</button>
</body>
<script type="text/javascript">
var seed = 0;
var soil = 0;
function russetPotato(){
seed = 1
document.write("You set seed as Russet Potato.");
}
function redPotato(){
seed = 2
document.write("You set seed as Red Potato.");
}
function sweetPotato(){
soil = 1
document.write("You set seed as Sweet Potato.");
}
function sandySoil(){
soil = 1
document.write("You set soil as Thin Sandy Soil.");
}
function loamSoil(){
soil = 2
document.write("You set soil as Loose Loam Soil.");
}
function claySoil(){
soil = 3
document.write("You set soil as Heavy Clay Soil.");
}
</script>
</html>
道歉，如果這其實很簡單。這是我第一次使用javascript/html進行實驗。
