我到处寻找答案，我认为这是一个有点简单的问题。我所看到的所有答案都说使用'.text()'，这不起作用。

在Jquery mobile中，我想简单地将listview中的标题文本替换为我在该listview中选择的单选按钮的文本。为了简单起见，只需动态更改列表视图中标题的文本就足够了。问题是，如果不删除一些HTML，我就无法动态更改列表视图标题的文本。我尝试了来自stackoverflow和其他网站的许多建议，包括:

我正在android设备上使用以下代码进行测试:

• Cordova版本:6.3.1
JQuery 1.11.0
JQuery mobile 1.4.5

这是什么HTML我试图操纵看起来像渲染前:

<h2 id="h2-test-area">Area</h2>

文本"Area"是我想要改变的。

这是什么HTML我试图操纵看起来像渲染后:

<h2 id="h2-test-area" class="ui-collapsible-heading">
    <a href="#" class="ui-collapsible-heading-toggle ui-btn ui-btn-icon-right ui-btn-inherit ui-icon-minus">
        Area
        <span class="ui-collapsible-heading-status"> click to collapse contents</span>
        ::after
    </a>
</h2>

Javascript:

$("input[name='rad-test-area']").on("change", function() {
    $("#h2-test-area a.ui-collapsible-heading-toggle").text("new text");
});

当我执行上面的javascript时，它取代了我想要的文本，但它也取代了HTML中文本"Area"之后出现的span。为什么每个人都说'.text()'工作时，它清楚地删除HTML?提前感谢您的帮助

<h2 id="h2-test-area"><span id="h2-test-area-span">Area</span></h2>

$("input[name='rad-test-area']").on("change", function() {
    $("#h2-test-area-span").text("new text");
});

$("input[name='rad-test-area']").on("change", function() {
    $("#h2-test-area a.ui-collapsible-heading-toggle").html().replace("Area", "new text");
});
