缓慢刷新jQuery Mobile单选按钮?

jQuery 1.7.1和jQuery Mobile 1.1.0RC1

您好,我的网站上有一个JQM单选按钮,并且我根据我在页面显示时检查的条件以编程方式更改其值。一切都运行良好,但它并非发生得非常“平滑”,我的意思是当用户改变时它是非常明显的,即它处于原始状态半秒左右然后切换。也许我有点挑剔,但我希望切换对用户透明。我仍然试图理解各种JQM“page *”事件,并且如果我在pagebeforeshow或pagebeforecreate上做了它会使这种情况发生,但事实并非如此。

我试图为它做一个jsFiddle(我的第一次),它在那里发生了很快(可能与我在选项中选择onDomReady有关吗?)但是应该让你知道我是什么谈论...在我的网站上,当页面加载然后切换到开启时,选择显然处于关闭状态。这不是什么大不了的事,我要求更多帮助我理解各种页面*事件。

更多信息:

Web应用程序基本上是一个文档浏览器,构造如下:index.html文件包含文档列表,或者更确切地说是指向可用文档的TOC的链接列表。每个TOC都包含指向实际文档各部分的链接。

代码如下......因为我是初学者,所以很可能充满了糟糕的风格。我的单选按钮问题的代码在custom2.js的第30-39行和ch2-sec1.html的23-28中。另请注意,当样式表以styleDay.css结尾时,custom2.js中的console.log($("link[href$='styleDay.css']").length);代码行打印出“2”,我不知道为什么(我希望它为“1”)。但是,我的主要问题是浏览内容文件时存在明显的延迟(例如ch2-sec1.html,如下所示),当条件为真时,代码将单选按钮翻转为“日间模式”...不能对它进行编码,以便在页面可见时已经翻转了吗?
