Question

在我的用例中，我将使用javascript动态替换带有文本框的两个标签。我想从文本框中获取更新的值。但是它提供了标签中的原始内容而不是文本框中的更新值。

原来的div：

label1的
lable2
EditButton

按下EditButton后，

文本1
文本2
UpdateButton

我将编辑Tex1，Text2中的内容并按下UpdateButton我期望javascript中Text1，Text2的编辑值，但我从label1，label2获取原始值。

我的Javascript代码在这里，

var originalQuestion = "";
$('.questiondiv').on('click', '.edit_question_button', function() {
    console.log("In submit edit question text area");
    var pageURL = $('#page_url').text();
    var loggedUser = $('#logged_user').text();
    if (!loggedUser) {
        console.log("In answerbutton redirect");
        window.location.href = "/login/?redirect="+pageURL;
    } else {
        console.log("question edit");
        var title_val       = $(this).closest('.question-inner').find('.quest_title_val').text();
        var question_val    = $(this).closest('.question-inner').find('.quest_text_val').text();
        console.log("Question title value ", title_val);
        console.log("Question value ", question_val);

        var newdiv = "<div class='question-inner'><div class='form-input updated_question'><input name='question_title_val' id='question_title_val' type='text' size='81' value='"+title_val+"' /></div> <br /> <div class='form-input'><textarea name='question_text_val' id='question_text_val' rows='8' cols='80'>"+question_val+"</textarea><br /><div class='form-input'><a type='Submit' id='updatequestion'  name='updatequestion' class='btn btn-primary updatequestion'>Update Question</a><a type='Cancel' id='cancelupdatequestion' name='cancelupdatequestion' class='btn btn-primary cancelupdatequestion'>Cancel</a></div></div></div>";
        originalQuestion = $(this).closest('.question-inner').html();
        $(this).closest('.question-inner').replaceWith(newdiv);
    }
});

$('.questiondiv').on('click', '.updatequestion', function() {
    console.log("In update question button");
    var question_id = $(this).closest('li').find('.question_id_val').val();
    quest_inner = $(this).closest('.question-inner').html();
    console.log("In update question button :: quest inner content ", quest_inner);
    var quest_title = $(this).closest('.question-inner').find('#question_title_val').text();
    var quest_val   = $(this).closest('.question-inner').find('#question_text_val').text();
    $.getJSON("/question?question_id="+question_id+"&question_title"+quest_title+"&question_val="+quest_val, function(data) {
        console.log("update question Response "+data);
        $(this).closest('.updated_question').replaceWith(originalQuestion);
    });
});

我的HTML，

<div class="qanda questiondiv" id="questionarea" name="questionarea">
    <div class="question-inner">
        <div>
            <div id="topic" class="upvote pull-left">
                <a class="upvote"></a>
                <span class="count">3</span>
                <a class="downvote"></a>
            </div>
            <div >
            <div class="qanda-info">
                    <h6><p class="quest_title_val">{{.QuestionTitle}}</p></h6>
                </div>
                <p class="quest_text_val">{{.QuestionText}}</p>
            </div>
        </div >
        <div class="qanda-info">
            <div class="user-info">
                <a href="/userprofile/{{.UserId}}" ><img src="http://tinygraphs.com/spaceinvaders/Dany?theme=frogideas&numcolors=4&size=220&fmt=svg"/>
                </a>
            </div>
            <h6>{{.UserId}}</h6>
            <span class="date alt-font sub">{{.DateCreated}}</span>
            [<a class="edit_question edit_question_button" >edit</a>|<a class="delete_question_button" id="delted" >delete</a>]<br>
            <a id="answertext" name ="answertext" type="submit" class="link-text answerbutton">Answer</a>
        </div>
    </div>
</div>

有人可以帮我吗？
