【问题描述】：

你好，我的功能 questionAnswer 根本不起作用。假设提示关闭 switch 命令。我用这个网站寻求帮助。 http://www.w3schools.com/jsref/met_win_prompt.asp

var keyword1 = "how are"
var keyword2 =  "what are" 
var keyword3 = "creator"
var keyword4 = "why"
var keyword5 = "how did"
var keyword6 = "Where were"
var keyword7 = "what do"
var keyword8 = "color"
var keyword9 = "Bye" 
var keyword10 = "animal"
var keyword11 = "Hello"

var robotAnswer1 = "Good"
var robotAnswer2 = "I am the new Lego “Dames” droid 7.0. I am the newest and most  advanced robot in this century!"
var robotAnswer3 = "My creator is James Day, I was programmed by Emanuel “Kiwi Elefant” Rotible"
var robotAnswer4 = "I was made to inspire imagination and bring smiles!"
var robotAnswer5 = "I was created with state-of-the-art technology in a lab."
var robotAnswer6 = "In a lab at Lego’s Headquarters"
var robotAnswer7 = "I can talk, move listen, respond and can teach programming to kids"
var robotAnswer8 = "I do not know what you are trying to say" 
var robotAnswer9 = "I was made to inspire imagination and bring smiles"
var robotAnswer10 = "I was created with state-of-the-art technology in a lab"
var robotAnswer11 = "In a lab at lego's Headquarters"

function questionAnswer()  {
var text;
var questionAnswer = prompt(“Ask me a Question!”);
switch(questionAnswer) {
    case questionAnswer :
    	text = "Excellent choice! Whatever you said is good for your soul.";
        break;
    case keyword1:
    	text = robotAnswer1;
        break;
case keyword2:
    	text = robotAnswer2;
        break;
case keyword3:
    	text = robotAnswer3;
        break;
case keyword4: 
    	text = robotAnswer4;
        break;
case keyword5: 
    	text = robotAnswer5;
        break;
case keyword6:
    	text = robotAnswer6;
        break;
}

【问题讨论】：

你检查过控制台吗？你的代码有问题case :。
我想你会发现你的问题出在空壳上，...case : text = "Excelle...，你试过用devtools调试它吗？
为什么在 HEAD 中有一个表单？
对不起........我会试试的。
而不是使用大小写，有keywords = { "how are you": "Good", "what are you":"I am the new....\"Dames\".....", ..... }所以你可以使用keywords[answer]代替

标签： javascript html

【解决方案1】：

首先，将function questionAnswer {替换为function questionAnswer () {

其次，您在function questionAnswer 末尾缺少} 闭包

第三，将所有“实例替换为"或'

第四，第一种情况，case : 是空的 - 把一些值放在那里。

第五，正如 mplungjan 建议的那样，将表单放入正文中。

作为一般做法，请使用调试器测试您的 html，例如，在 Chrome 中，按 F12 并刷新页面以查看是否有任何错误。

希望对你有帮助

第六，因为文本没有在任何地方使用，“计算”值将被简单地丢弃。暂时没有输出。
好点@Thomas，让我们假设代码的逻辑要继续。
