第一個和第二個函式（n1 和 n2）都從它們各自的陣列中輸出一個亂數到控制臺。當我嘗試將這兩個生成的值相加并將結果也顯示在控制臺中時，就會出現問題。我嘗試創建一個全域變數來添加結果，但它不起作用。
如果 n1() 輸出 3 和 n2() 輸出 1，我希望控制臺輸出 4。
這是我的代碼：
var add = (n1() n2());
function n1() {
var cpuSelection = [1, 2, 3];
var randomSelection = cpuSelection[Math.floor(Math.random() * cpuSelection.length)];
console.log(randomSelection)
}
n1();
function n2() {
var cpuSelection = [1, 2, 3];
var randomSelection = cpuSelection[Math.floor(Math.random() * cpuSelection.length)];
console.log(randomSelection)
}
n2();
console.log(add)uj5u.com熱心網友回復：
console.log( (n1() n2()));
function n1() {
var cpuSelection = [1, 2, 3];
var randomSelection = cpuSelection[Math.floor(Math.random() * cpuSelection.length)];
console.log(randomSelection)
return randomSelection;
}
function n2() {
var cpuSelection = [1, 2, 3];
var randomSelection = cpuSelection[Math.floor(Math.random() * cpuSelection.length)];
console.log(randomSelection)
return randomSelection;
}

就像 DM 說的，你可以回傳那些隨機值。
function n1() {
var cpuSelection = [1, 2, 3];
var randomSelection = cpuSelection[Math.floor(Math.random() * cpuSelection.length)];
console.log(randomSelection)
return randomSelection;
}
n1();
function n2() {
var cpuSelection = [1, 2, 3];
var randomSelection = cpuSelection[Math.floor(Math.random() * cpuSelection.length)];
console.log(randomSelection)
return randomSelection;
}
