【问题描述】：
我正在寻找基于问题选项的所有可能的问题答案路径，我整天绞尽脑汁，似乎无法弄清楚为什么我的代码不起作用。
测试代码：
const originalQuestions = {
1: {
title: "Title",
firstQuestion: true,
options: [{
tooltip: "",
nextQuestion: 2
}, {
tooltip: "",
nextQuestion: 2
}, {
tooltip: "",
nextQuestion: 10000
}]
},
2: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 3
}, {
tooltip: "",
nextQuestion: 3
}, {
tooltip: "",
nextQuestion: 3
}, {
tooltip: "",
nextQuestion: 3
}]
},
3: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 4
}, {
tooltip: "",
nextQuestion: 4
}, {
tooltip: "",
nextQuestion: 4
}]
},
4: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 13
}, {
tooltip: "",
nextQuestion: 5
}]
},
5: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 6
}, {
tooltip: "",
nextQuestion: 6
}, {
tooltip: "",
nextQuestion: 6
}, {
tooltip: "",
nextQuestion: 10000
}]
},
6: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 7
}, {
tooltip: "",
nextQuestion: 7
}, {
tooltip: "",
nextQuestion: 7
}, {
tooltip: "",
nextQuestion: 7
}, {
tooltip: "",
nextQuestion: 14
}]
},
7: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 17
}, {
tooltip: "",
nextQuestion: 17
}, {
tooltip: "",
nextQuestion: 17
}, {
tooltip: "",
nextQuestion: 17
}, {
tooltip: "",
nextQuestion: 17
}]
},
8: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 9
}, {
tooltip: "",
nextQuestion: 9
}, {
tooltip: "",
nextQuestion: 9
}]
},
9: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 10
}, {
tooltip: "",
nextQuestion: 10
}, {
tooltip: "",
nextQuestion: 10
}]
},
10: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 11
}, {
value: "Roof",
attribute: "Flue Exit",
tooltip: "",
nextQuestion: 15
}]
},
11: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 12
}, {
tooltip: "",
nextQuestion: 12
}]
},
12: {
finalQuestion: true,
input: true,
placeHolder: 'e.g SWS'
},
13: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 6
}, {
tooltip: "",
nextQuestion: 6
}]
},
14: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 7
}, {
tooltip: "",
nextQuestion: 7
}, {
tooltip: "",
nextQuestion: 10000
}]
},
15: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 12
}, {
tooltip: "",
nextQuestion: 12
}]
},
17: {
title: "Title",
options: [{
tooltip: "",
nextQuestion: 8
}, {
tooltip: "",
nextQuestion: 8
}, {
tooltip: "",
nextQuestion: 8
}, {
tooltip: "",
nextQuestion: 8
}, {
tooltip: "",
nextQuestion: 8
}]
},
// Errors
10000: {
isError: true,
title: "Finally, what is the first part of your postcode?",
error: "Postcode"
}
};
function loopPaths(currentArrayPath, questionNum, currentQuestion, paths) {
if (questionNum > 5) {
return false;
}
if (typeof currentQuestion.finalQuestion != 'undefined') {
return false;
} else {
const question = currentQuestion.options;
const validPaths = question.filter((e) => e.nextQuestion !== 10000);
const clonedPath = [...paths[currentArrayPath][0]];
for (var i = 0; i < validPaths.length; i++) {
const e = validPaths[i];
if (typeof paths[currentArrayPath][i] == 'undefined') {
paths[currentArrayPath][i] = [...clonedPath];
}
paths[currentArrayPath][i].push(questionNum);
loopPaths(currentArrayPath, e.nextQuestion, originalQuestions[e.nextQuestion], paths);
}
}
}
function possiblePaths() {
const question1 = originalQuestions[1].options;
const validPaths = question1.filter((e) => e.nextQuestion !== 10000);
let paths = [];
/*validPaths.forEach((e, i) => {
paths[i] = [[1]];
});*/
/*
for (var i = 0; i < validPaths.length; i++) {
const e = validPaths[i];
loopPaths(e.nextQuestion, boilerQuestions[e.nextQuestion], paths);
} */
// Testing with first question, first option
paths[0] = [[1]];
loopPaths(0, 2, originalQuestions[2], paths);
console.log(paths);
}
possiblePaths();似乎发生了什么：（它没有构建正确的路径，也没有构建不同的可能性）

它应该显示的示例：（我想知道是否有更简单的方法来构建从 1 -> 到最终问题 12 的不同可能性）

工作原理：
用户点击问题 1 -> 按下选项 1 -> 用户点击问题 2 -> 按下选项 2 -> 用户点击问题 3 -> 按下选项 1 -> 用户点击问题 4 -> 按下选项 1 -> 用户点击问题13
