javascript - 如何验证 arangements(sequence) 的div内的标签或文本？

Question

我想检查安排以验证拖放事件后它是否处于正确位置

<div class="container" id="con">
    <p class="draggable" draggable="true" id="p1">1</p>
    <p class="draggable" draggable="true" id="p2">2</p>
    <p class="draggable" draggable="true" id="p3">3</p>
    <p class="draggable" draggable="true" id="p4">4</p>
</div>

现在这是我对我的问题的回答。知道了

function myFunction() {
        var c = document.getElementById('con').children;
        var txt = "";
        var i;
        for (i = 0; i < c.length; i++) {
          txt = txt + c[i].lastChild.textContent  ;
        }
