选择子div的文本

Question

我有以下情况，如下图所示

1. 我使用文字'task1'
编辑了任务
2. 将文字更改为“task2”
3. 屏幕上出现新文字“task2”。

但是我在编辑文本时遇到问题并将其存储在变量中。

如何使用jquery从div id =“taskDiv”的子div中选择文本（在本例中为task2）？



代码javascript：

$(".list_of_items").on("click", "button.edit", function (){
        event.preventDefault();
        var myText = $(this).closest("div.text_holder").text();
        var textBox = "<div id='taskDiv'><form class='edit_input_box'><input type='text' value='" + myText + "' class='itembox'></form></div>";
        var deleteButton = "<button class='delete btn btn-danger btn-sm'><span class='glyphicon glyphicon-trash'></span></button>";
        var editButton = "<button class='edit btn btn-success btn-sm'><span class='glyphicon glyphicon-pencil'></span></button>";
        var twoButtons = "<div class='btn-group'>" + deleteButton + editButton + "</div>";

        var textToSend = $(this).closest("div.text_holder").replaceWith(textBox); //replace with new word written 

        $("form.edit_input_box").on("submit", function(){
            var checkBox = "<label><input type='checkbox'></label>";
            //var noteId = $(this).closest("li").attr("id"); //take unique note id
            //sendUpdatedNoteToDb(noteId,textToSend);
            $(this).replaceWith("<div>" + $(".itembox").val() + twoButtons + "</div>");
        }); 

代码html：

<div class="form-inline">
                <h1>Learning jquery</h1>
                <form role="form" id="main_input_box_dub2az">
                    <label> <input type="text" class="form-control"
                        id="txtField_dub2az" name="Item" placeholder="Site note:"
                        aria-describedby="name-format" required> <input
                        type="submit" value="Add" id=btnAdd_dub2az
                        class="btn btn-primary add_button">
                    </label>
                </form>
                <div>
                    <ol class="list-group list_of_items" id="dub2az"></ol>
                </div>
                <div class="container">
                    <div id="container" class=".col-xs-6 .col-sm-4"></div>
                </div>
            </div>
