我的功能被破坏似乎是Javascript

Question

基本上无论我在调用函数时输入的是什么，它都说你已经逃离了。我可能只是忽略了一些东西，但我无法弄清楚是什么。

    function attack() {
var battle = prompt("Attack of Flee?")
if (battle === "Flee" || "flee") {
    alert("You have fled");
    } 
else if (battle === "Attack" || "attack"){
    alert("You have attacked");
}   
    }

Answer 1

试试if (battle === "Flee" || battle === "flee") 右边只是评估字符串“逃离”的真实性，它总是评估true。

Answer 2

此if条件中的

1. if (battle === "Flee" || "flee") 你应该写

   if (battle === "Flee" || battle === "flee")

如果您想忽略大小写，那么如果您将字符串更改为小写，则会打击 这是示例

function attack() {
    var battle = prompt("Attack of Flee?");
    if (battle.toLowerCase() === "flee") {
        alert("You have fled");
    } else if (battle.toLowerCase() === "attack") {
        alert("You have attacked");
    }
}

Answer 3

尝试：

function attack() {
    var battle = prompt("Attack of Flee?");
    var ActionTaken = "";
    if (battle.ToLowerCase() == "flee") {
        ActionTaken = "You have fled";
    } 
    else if (battle.ToLowerCase() == "attack") {
        ActionTaken = "You have attacked";
    }
    alert(ActionTaken);
}
