Question

我想知道是否存在可以使用jQuery UI

添加新部分的方法

这是我到目前为止所做的没有任何错误，但是因为我添加了一个新手风琴后手风琴不起作用

$( function() {
    $( "#accordion" ).accordion();

    $('#addNewSection').on('click', function() {
        var newH3 = document.createElement('h3');
        var newDiv = document.createElement('div');
        var acc = document.getElementById('accordion');
        var number = document.getElementsByTagName('h3').length;

        newH3.innerText = 'Section' + (parseInt(number) + 1) + "(This won't collapse)";
        newDiv.innerText = 'This is a new section after clicking the button';
        acc.appendChild(newH3);
        acc.appendChild(newDiv);
    });
} );

h3 { background-color: "blue"; }
div { background-color: "lightgreen"; }

<div id="accordion">
    <h3>Section 1 (collapsible)</h3>
    <div>
        <p>
        This is the context in section 1
        </p>
    </div>

    <h3>Section 2 (collapsible)</h3>
    <div>
        <p>
        This is the context in section 2
        </p>
    </div>
</div>
<button id="addNewSection">AddOne</button>

<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

如何解决？或者我可以使用任何官方方法吗？

您可以在点击事件结束时使用refresh手风琴方法（Documentation）：

$( function() {
    $( "#accordion" ).accordion();

    $('#addNewSection').on('click', function() {
        var newH3 = document.createElement('h3');
        var newDiv = document.createElement('div');
        var acc = document.getElementById('accordion');
        var number = document.getElementsByTagName('h3').length;

        newH3.innerText = 'Section' + (parseInt(number) + 1) + "(This WILL collapse)";
        newDiv.innerText = 'This is a new section after clicking the button';
        acc.appendChild(newH3);
        acc.appendChild(newDiv);
       $( "#accordion" ).accordion("refresh");
    });
} );

h3 { background-color: "blue"; }
div { background-color: "lightgreen"; }

<div id="accordion">
    <h3>Section 1 (collapsible)</h3>
    <div>
        <p>
        This is the context in section 1
        </p>
    </div>

    <h3>Section 2 (collapsible)</h3>
    <div>
        <p>
        This is the context in section 2
        </p>
    </div>
</div>
<button id="addNewSection">AddOne</button>

<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
