jquerymobile phonegap back按钮获取先前状态

I'm building an little mobile app and I got a question about JQM.

我正在开发一个移动应用程序，我有一个关于JQM的问题。

When the user is logged in the user will be redirected to page A. Page A is loaded with the loadPage from JQM (example: $.mobile.loadPage("pageA.html"))

当用户登录时，将被重定向到A页。页面A装载了来自JQM的loadPage(例如:$. mobiley .loadPage(“page .html”))

After the page is loaded, I do an AJAX-call because I pull some data from a database and change the content on page A. From page A, I can go to page B. page B has an back-button. When I click on the back-button, the app slides back to the state without the AJAX content. Is there a way to fix this?

加载页面后，我进行ajax调用，因为我从数据库中提取一些数据，并更改页面a上的内容。当我单击back按钮时，应用程序就会滑回到没有AJAX内容的状态。有办法解决这个问题吗?

Thanks

谢谢

By default, jQuery Mobile will remove any page brought into the DOM via AJAX once the user navigates away from the page. If you want to disable this feature for a specific page you can add the data-dom-cache attribute to the data-role="page element for the page and set it to true:

默认情况下，jQuery Mobile将在用户离开页面后，通过AJAX删除任何进入DOM的页面。如果您想要禁用特定页面的此特性，可以将data-dom-cache属性添加到页面的data-role="page element，并将其设置为true:

<div data-dom-cache="true" data-role="page" id="pageA">
    ...
</div>

This feature was added to jQuery Mobile to help control the size of the DOM so less browser crashes will occur. If you just want to keep a single page in the DOM then make sure it's not a huge page that will bog-down the device.

这个特性被添加到jQuery Mobile以帮助控制DOM的大小，从而减少浏览器崩溃的发生。如果您只想在DOM中保留一个页面，那么请确保它不是一个会使设备陷入困境的大页面。
