更改按钮文本jquery mobile [英] Change button text jquery mobile

问题描述

我使用新的jquery mobile 1.0 alpha 1版本来构建移动应用程序，我需要能够切换按钮的文本。

I'm using the new jquery mobile 1.0 alpha 1 release to build a mobile app and I need to be able to toggle the text of a button. Toggling the text works fine, but as soon as you perform the text replacement the css formatting gets broken.

    <div class="ui-bar">
        <a data-role="button" href="#" onclick="Podcast.play(); return false" id="play">Play</a>
        <a data-role="button" href="#" onclick="Podcast.download(); return false" id="download">Download</a>
        <a data-role="button" href="#" onclick="Podcast.consumed(); return false" id="consumed">Mark Old</a>
    </div>

$("#consumed").text("Mark New");

推荐答案

创建按钮时会添加一些额外的元素，一些内部< span> 元素如下所示：

When you create the button it adds some additional elements, some inner <span> elements that look like this:

<a data-role="button" href="#" onclick="Podcast.consumed(); return false" id="consumed">
  <span class="ui-btn-inner ui-btn-corner-all">
    <span class="ui-btn-text">Mark Old</span>
  </span>
</a>

要更改文本，您需要此选择器：

To change the text, you'll want this selector:

$("#consumed .ui-btn-text").text("Mark New");
