Question

jquery mobile新手。试图建立我的第一个jquery移动应用程序。应用程序要求是一些左右面板的页面。有很多动态数据，如页面标题，左侧面板列表（包含图像和通过JSON对象的标题），右侧面板，所有页面链接也将动态。一切都工作正常但在访问第2页后我们再次访问第1页时，面板搞砸了。页面标题不会更新。似乎重新访问页面不会捕获写在js和css文件上的样式和函数。这是演示。 HTML https://jsfiddle.net/brunocoder/x5j0jqgt/3/

在您的网页创建中，您正在呼叫：

$("[data-role='header'] h1").text($(this).jqmData("title"));

这会将文本写入DOM中的所有标题h1，因此当您访问第2页时，它也会覆盖第1页上的标题。将行更改为：

$(this).find("[data-role='header'] h1").text($(this).jqmData("title"));

这可确保您只更新正在创建的页面中的标题。

对于面板，由于每个页面都有单独的处理程序，因此将处理程序更改为

$(document).on("pagebeforecreate", "#page-1", function(){ ...

和

$(document).on("pagebeforecreate", "#page-2", function(){ ...

这可确保它们仅对即将创建的页面运行一次。
