所以我只知道你的基本 HTML 和 CSS。我可以操纵那里的东西并弄清楚它，但我不是开发人员，我能从头开始写的东西非常有限。
我正在尝试使用 javascript 提示函数和 if 语句创建交互式测验。我已经运行了代码，但是我需要做一些我无法弄清楚的事情。我已经搜索并没有运气收到我的问题的 [简单] 解决方案。
PS。我知道只有一个像这样的大型脚本可能不是一个好习惯，但如果可能的话，请帮助我完成我所拥有的。提前感谢您的帮助，这是我的功能： https ://gist.github.com/anonymous/dcde24cf97df24fe5ca4
你的问题非常广泛，因为总是有一百万种设计方法，但我会给你五分钟的答案。
使用数据结构来保存您的问题/答案组合，例如对象数组。如果您想让用户沿着“路径”前进，那么数组是有意义的。您只需遍历数组即可提出问题。
var questions = [{
question: 'Are you happy?',
answer: 'yes',
affirm: 'Yay! You got it right!',
rebuttal: 'Nope, you are definitely happy.'
},
{
question: 'Are you mad?',
answer: 'no',
affirm: 'Good job!',
rebuttal: 'Not right.'
}];
for (var i = 0, l = questions.length; i < l; i++) {
answer = prompt(questions[i].question);
// I do not support manipulating a loop counter mid-loop, but it's for an example.
if (answer !== questions[i].answer) {
alert(questions[i].rebuttal);
i--;
} else {
alert(questions[i].affirm);
}
}
老实说，使用您的方法非常原始，您必须使用必须在提示文本中编写选项。对于多个答案，您必须强制用户以某种方式分隔他们的答案（例如，使用逗号）。但老实说，我会完全放弃提示/警报方法，并使用 HTML 元素来实现您的目标（假设这是在 Web 浏览器中）。
似乎其他用户已经解决了您的语法错误。
如果您对这些概念中的许多概念感到陌生，我建议您在Codecademy学习，因为他们有关于 Javascript 和 HTML 的优秀课程。
在您的问题中，大括号不匹配。查看函数大括号完成的位置。这是第三个问题。
尝试
function welcome() {
confirm("Welcome! You have chosen to play. You will be presented with a series of questions...");
confirm("If you answer a questions incorrectly, you cannot advance to the next...");
var retVal = prompt("Do you want to continue?");
if (retVal == "yes") {
alert("Good, question 1...");
} else {
alert("Well you're boring");
}
//Question 1
var retVal = prompt("The term jitterbug originally was a slang term for a person who was real heavy on jittersauce. What does jittersauce refer to?");
if (retVal == "alcohol") {
alert("Not bad, next question...");
} else {
alert("FALSE. Please try again. HINT: it makes parties fun...");
}
//Question 2
var retVal = prompt("What early American Broadway show helped popularize swing dance styles, ranging from the Charleston to the Foxtrot?");
if (retVal == "Ziegfeld Follies") {
alert("Dang, pretty impressive. NEXT");
} else {
alert("NOPE. HINT: starts with a Z...");
}
//Question 3
var retVal = prompt("What ballroom style is inspired by the traditional Spanish bullfight?");
if (retVal == "paso doble") {
alert("Very good... your Googling skills are excellent.");
} else {
alert("WRONG. HINT: it's in Spanish...");
}
//Question 4
var retVal = prompt("Ballroom dancing gets its name from what Latin term?");
if (retVal == "ballare") {
alert("More like BALLER... HAH, ok next.");
} else {
alert("Really? Come on. HINT: it's got the word ball in it...");
}
//Question 5
var retVal = prompt("What Latin dance style is the official dance of the Dominican Republic?");
if (retVal == "Merengue") {
alert("Tastes like lemons, time for the final question");
} else {
alert("INCORRECT. HINT: starts with an M and rhymes with a fruit pie...");
}
//Question 6
var retVal = prompt("What Latin dance style is a combination of the Mambo and the Rumba?");
if (retVal == "cha cha") {
alert("YOU WIN YOU WIN YOU WIN... click OK to claim your prize");
} else {
alert("DUR NO. HINT: this is a text message service that will answer any question you text them...");
}
//Prize
var retVal = prompt("This is your prize. Will you accept?");
if (retVal == "yes") {
alert("Good. Comence prizing.");
} else {
alert("Why you no want prize?");
}
}
我喜欢使用这段代码，因为它既好又简单。无论如何，这是代码：
var q; function w(e,r){while(q!=r){q=prompt(e);};}; w("question", "answer");如果你只是添加一个;然后w("whatever your question is", "whatever your answer is")在最后，它会添加另一个问题。但不要忘记问题和答案之间的逗号。
但是如果你想选择你想要它做什么，那么你使用这个：
var x=prompt("what is 1+1?"); if(x=="2"){alert("yep!")} else{alert("no.")};
