Wit*_*tek 21 javascript navigation jquery jquery-mobile
我的jQuery Mobile应用程序由一个index.html页面组成,并且在启动时只包含一个带有链接的页面:
<div data-role="page">
<div data-role="content">
<a id="startPageLink" href="startPage">start</a>
</div>
</div>
当用户点击开始链接时,我想startPage异步加载来自我的JSON api 的内容.在回调中,我想为startPagevia JavaScript 创建所有必需的DOM元素,并将内容添加到它.我createStartPage(data)为此创建了一个方法.
实现这种动态创建的页面的正确方法是什么,这样开放index.html#startPage也有效？我认为应该有一种方法来$.mobile.changePage()包含自定义加载/页面创建代码,但我没有找到任何东西.或者这个问题有更好的解决方案吗？

我有时间搞乱这个,我找到了一个有效的解决方案.
