数据结构类型

Question

我有多个包含子问题的问题。 我想存储在数据结构中，以便当用户选择第一个问题时可以选择子问题。 同样，某些子问题在该类别中使用常规问题。 最初，我考虑过使用多维数组，但后来我意识到搜索数组需要花费很长时间。

任何建议表示赞赏。

谢谢

到目前为止，这是我的解决方案。

//Key is the question and value(object) contains all the value related to the question
categoryToSubquestions[2] = {"What type of countertop?":{
                                "stone_slab_countertops": "Stone slab countertops",

                             "generalQuestions2": "4"
                            };
//This is general question that other categories might use...It is being used in the above category
generalQuestion[4] = {"Is this project part of a larger remodel?":{
                            "true" : "Yes",

                    };
//THIS IS categoryToSuquestion index to value assosciation...(JUST TO KEEP TRACK)
var keyValue = new Array(
/*0*/           "cabinets_reface",
/*1*/           "cabinets_refinish",
/*2*/           "cabinets_countertop_install");

我现在有70个，我不担心一旦我继续添加更多问题，它是否会变慢？

我将创建一个这样的数据结构。
不要忘记，您可以像在其属性上的哈希表/字典一样访问它。

var questions_data_structure = {
    "Q1": {
        "question_text": "Parent Question #1?",
        "sub_questions": ["SubQues1", "SubQues3"]
    },
    "SubQues1": {
        "question_text": "Sub Question 1?",
        "parent_question": "Q1"
    },
    "SubQues3": {
        "question_text": "Sub Question 3?",
        "parent_question": "Q1"
    },
    "Ques8": {
        "question_text": "Regular question without children questions?"
    }
}

q = questions_data_structure["Q1"];
alert(q.question_text);

if (q.sub_questions && q.sub_questions.length > 0) {
    alert("I have child questions");

    var i = 0, len = q.sub_questions.length, childQuestionObj;
    for (; i < len; i++) {
        childQuestionObj = questions_data_structure[q.sub_questions[i]];
        alert(childQuestionObj.question_text);
    }
}
else {
    alert("I DON'T have child questions");
}

因此，如果将数据结构的KEY值绑定到HTML控件ID，则可以执行类似的操作。

// include jQuery library
$.each(questions_data_structure, function(question_id, value) {
    if (value.sub_questions && value.sub_questions.length > 0) {
        $('#' + question_id).click( function(e) {
            /* Show or hide your child question controls */
        });
    }
});
