如何在 if 语句中添加多个命令？JavaScript

我觉得这个实例真的很简单，我可能想多了，但是有没有办法在我的 if 语句中添加多个语句？我正在寻找类似的东西，如果我在我的游戏中选择去某个方向，你会得到这样的文字“你决定去商店。你想探索吗？” 并且有两种选择：

- 是的，然后在输入框中输入“是”，然后它会给出“探索后，你决定买东西”的结果

-不，你决定离开。

我一直试图弄清楚一个多小时，当我接近时，即使你不在那个位置，命令仍然可以访问。例如。我的游戏中的位置是，“你在公园里。如果在输入框中随机输入，“是”命令将返回“探索后，你决定买东西”

我希望这样，如果您在该特定位置，则只能在该位置访问该代码，而不能在其他任何地方访问。

因此，如果您在公园作为地点并随机输入“是”，则不会发生任何事情，因为您不在商店的位置。

这是我的代码：

...

选择一个方向

<input id = "input" type = "text" placeholder = "Type 'Help1' for actions"/><button onClick = "button()">Confirm Action</button>
<p id = "message"></p>

<script>

  function button() {
    var textInput;
    var newInput = input.value;
    if (newInput == "North") {

      textInput = "you went to the Store. Do you explore?"; // <-- I'd like a way to put in "Yes" as a response which would print out a text saying "You explored the store and bought some food" //

      document.getElementById("message").innerHTML = textInput;

    }


    if (newInput == "North Again") {
      textInput = "you went to the Forest Home";
      document.getElementById("message").innerHTML = textInput;
    }

    if (newInput == "Help1") {
      textInput = "[Page 1 of 2. Type 'Help2' for page 2] Commands you can use: <ul><li>South</li><li>North</li><li>East</li><li>West</li><li>North Again</li><li>South again</li><li>West Again</li><li>East Again</li>";
      document.getElementById("message").innerHTML = textInput;
    }

    if (newInput == "Help2") {
      textInput = "[Page 2 of 2] Commands you can use: <li>North One More</li><li>East Once More</li><li>West Once More</li><li>South Once More</li>";
      document.getElementById("message").innerHTML = textInput;
    }
  }

</script>

</div>

<div id = "stat-box">
  <h2 align = "center">STATS</h2>
</div>

执行此类操作的基本方法是将您的游戏状态存储在一个变量中，并且每次用户运行命令时，您都会修改游戏状态。查看此代码（如果您将其放入您的网站，它应该可以工作）：

<script>

var state = "init" // Initialize the game state

function button() {
    var textInput;
    var newInput = input.value;

    if (state == "init") {
        // Handle commands when game state is in "init"

        if (newInput == "Help1") {
            textInput = "[Page 1 of 2. Type 'Help2' for page 2] Commands you can use: <ul><li>South</li><li>North</li><li>East</li><li>West</li><li>North Again</li><li>South again</li><li>West Again</li><li>East Again</li>";
            document.getElementById("message").innerHTML = textInput;
        } else if (newInput == "Help2") {
            textInput = "[Page 2 of 2] Commands you can use: <li>North One More</li><li>East Once More</li><li>West Once More</li><li>South Once More</li>";
            document.getElementById("message").innerHTML = textInput;
        } else if (newInput == "North") {
            textInput = "you went to the Store. Do you explore?";
            state = "store"
            document.getElementById("message").innerHTML = textInput;
        }

    } else if (state == "store") {
        // Handle commands when game state is in "store"

        if (newInput == "Yes") {
            textInput = "There's a giant dragon in the cereal asile. Do you fight it?";
            state = "dragon"
            document.getElementById("message").innerHTML = textInput;
        } else if (newInput == "No") {
            // Change the state to something else
        }

    } else if (state == "dragon") {
        // Handle commands when game state is in "dragon"

        if (newInput == "Yes") {
            textInput = "You slayed the dragon!";
            document.getElementById("message").innerHTML = textInput;
        } else if (newInput == "No") {
            textInput = "You got eaten";
            document.getElementById("message").innerHTML = textInput;
        }

    }
}
