移动导航栏会在更改项目文本时调整大小 [英] mobile navbar resizes on changing text of an item
问题描述
我在jquery移动网站中有一个包含两个项目的导航栏:
I have a navbar with two items in a jquery mobile site:
<div data-role="content">
<div data-role="navbar">
<ul>
<li><a href="javascript:audioPause();" id="play-btn">Pause</a></li>
<li><a href="javascript:audioStop();" id="stop-btn">Stop</a></li>
</ul>
</div>
</div>
当我更改链接的文本时,使用$('#play-btn').text('Play');
会更改其大小,因此导航栏项目的高度仅是文本的高度.因此,在更改#play-btn的文本后,我最终得到了
When I change the text of the links, with $('#play-btn').text('Play');
its size changes, so that navbar item height is only that of the text. So after changing the text of #play-btn I end up with
+--------+--------+
| play | stop |
+--------| |
+--------+
我该如何解决? (我以为也许我需要告诉导航栏以某种方式再次绘制自身,但不知道如何.)
How can I get round this? (I thought maybe I need to tell the navbar to draw itself again somehow, but don't know how.)
谢谢.
推荐答案
在jQuery Mobile初始化按钮后,看看按钮的结构.要更改要使用.ui-btn-text
类定位元素的文本,请执行以下操作:
Take a look at the structure of a button after jQuery Mobile has initialized it. To change the text you want to target the element with the .ui-btn-text
class:
$('#play-btn').find('.ui-btn-text').text('Play');
这将保留所有正确的格式.您当前的代码正在覆盖按钮的HTML结构.
This will keep all the proper formatting. Your current code is overwriting the HTML structure of the button.
这是一个演示: http://jsfiddle.net/4NDcn/1/(注意我在不使用href
属性的情况下附加了click
事件处理程序)
Here is a demo: http://jsfiddle.net/4NDcn/1/ (Notice I attached click
event handlers without using the href
attribute)
这是jQuery Mobile 1.0的按钮结构:
Here is the structure of a button for jQuery Mobile 1.0:
<a id="play-btn" href="#" data-theme="c" class="ui-btn ui-btn-up-c ui-btn-active">
<span class="ui-btn-inner" aria-hidden="true">
<span class="ui-btn-text">Pause</span>
</span>
</a>
