JavaScript, 如何调用一个函数

Question

这可能听起来很愚蠢，就像 "Is this guy even trying?" 愚蠢一样。但我正在拼命地尝试。我搜索的所有内容都只向我展示了如何编写一个函数，而不是回调它。

var choice1 = function(){
    var choice = 5
        while(choice != "n" || "s") {
            document.write("<p>There's a door norh of which you sit, south is a small window with a slight breeze coming through</p>");
            document.write("<p> north: door  south: window</p>");
            choice = prompt("north or south");
            if(choice == "n" || "south"){
                document.write("<p>You stand up, aching in your joints you grunt. Inspecting the door you see, what seems to be, a large iron grated cell door? ''Why would I be in a cell?'' you think to yourself.</p>")
                break
            }else if(choice == "s" || "south"){
                document.write("<p>You stand up, aching in your joints you grunt. Inspectig the window</p>");
                break
            }else if(choice != "n" || "s" || "noth" || "south") {
                document.write("<p>Please pick one of the paths</p>");
        };
    };
};

function choice1()

这就是我所拥有的，它可以工作，因为我已经在不在函数中的情况下进行了测试，但我无法让它调用函数。

Answer 1

choice1()

键入 function 表示您想声明一个函数而不是使用一个函数。

Answer 2

将最后一行 function choice1() 替换为：

choice1()

Answer 3

要调用该函数，只需执行以下操作：

choice1();
