Question

我正在研究一个问答比较示例，我试图将问题字符串与json数据进行比较。问题和答案将作为json数据提取。你能帮我指导解决比较问题。

<label for="What_is_planning">What is planning</label>
<br>
<label for="What_is_implementing">What is implementing</label>
<br>
<div class="result"></div>


$(document).ready(function () {
    $('label').mouseover(function () {
        var helpString = this.firstChild.nodeValue.replace(':', '').trim();

        var answerString = "<br>No Answer";
        $(".result").html(" <hr><b>Guest: </b>" + helpString);
        $(".result").append(" <div><b>AskGFS: </b>" + answerString);
        console.log(helpString);
    });

    var QandAData = '{"gfsdata":[{"question":"what is planning","answer":"This is a important part of life"},' +
        '{"question":"what is implementing","answer":"this is followed by planning"}]}';

    //Comparing answers
    for (var i = 0; i < QandAData.length; i++) {
        if (QandAData[i].gfsdata.question == 'what is planning') {
            answerString = QandAData[i].gfsdata.answer;
        }
    }
});

Answer 1

尝试：

$(document).ready(function () {
    $('label').mouseover(function () {
        var helpString = this.firstChild.nodeValue.replace(':', '').trim();
        var answerString = "<br>No Answer";
        var QandAData = {
            "gfsdata": [{
                "question": "What is planning",
                "answer": "This is a important part of life"
            }, {
                "question": "What is implementing",
                "answer": "This is followed by planning"
            }]
        };
        for (var i = 0; i < QandAData.gfsdata.length; i++) {
            if (QandAData.gfsdata[i].question == helpString) {
                answerString = QandAData.gfsdata[i].answer;
            }
        }
        $(".result").html(" <hr><b>Guest: </b>" + helpString+" <div><b>AskGFS: </b>" + answerString);
    });
});
