使用JQUERY移动创建简单的页面 (CREATING A SIMPLE PAGE USING JQUERY MOBILE)
We have already covered the code it takes to build the basic structure for a mobile site, but we have not actually made it look like a mobile site. Let’s expand that into a one-page and one button site so that we can get a better feel for how jQuery Mobile works. jQuery Mobile designates pages using the data-role attribute. Behind the scenes, jQuery Mobile selects elements based on this attribute and progressively enhances them, adding CSS classes, any needed markup, and event management. This may seem like a complicated way of handling things – why not simply have regular pages linked like you ordinarily would? but this tutorial gives jQuery Mobile several important features:
我们已经介绍了构建移动网站基本结构所需的代码，但实际上并没有使其看起来像移动网站。 让我们将其扩展为一页和一个按钮的站点，以便更好地了解jQuery Mobile的工作方式。 jQuery Mobile使用data-role属性指定页面。 在后台，jQuery Mobile根据此属性选择元素并逐步增强它们，添加CSS类，任何需要的标记和事件管理。 这似乎是一种复杂的处理方式-为什么不像通常那样简单地链接常规页面呢？ 但是本教程为jQuery Mobile提供了几个重要功能：
Page Transitions By handling pages as separate content areas in one document, jQuery Mobile can create smooth page transitions, resulting in an overall ‘application-like’ look and feel.
页面转换通过将页面作为一个文档中的单独内容区域来处理，jQuery Mobile可以创建平滑的页面转换，从而产生整体“应用程序式”外观。
Navigation Management jQuery Mobile can automatically handle page navigation, providing features like back buttons and deep linking.
导航管理 jQuery Mobile可以自动处理页面导航，并提供后退按钮和深度链接等功能。
Efficiency Since resources are all contained in one file, the browser does not have to access the network over and over again, as it would with smaller individual files. This will help mitigate application slowness and battery drain on the mobile device. The trade-off is that for a large application there could be an appreciable download time for a large HTML page with many individual jQuery Mobile page views. However, once the file is downloaded and ready, the behavior will be much faster and will not necessarily be dependent on network access.
效率由于资源全部包含在一个文件中，因此浏览器不必像处理单个文件那样一遍又一遍地访问网络。 这将有助于减轻移动设备上的应用程序速度和电池消耗。 权衡是，对于大型应用程序，对于具有许多单独的jQuery Mobile页面视图的大型HTML页面而言，下载时间可能会相当可观。 但是，一旦下载并准备好文件，其行为将更快，并且不必依赖于网络访问。

第2.2节：JQUERY移动框架 (SECTION 2.2: JQUERY MOBILE FRAMEWORK)
移动初始化事件 (MOBILE INITIALIZATION EVENT)
The jQuery framework uses the
$(document).ready()function to circumvent manipulation and loading problems by giving you access to your functions as soon as possible. While this is fantastic for single page sites, it becomes a small problem for the jQuery Mobile framework.
jQuery框架使用
$(document).ready()函数使您能够尽快访问函数，从而规避了操作和加载问题。 尽管这对于单页网站来说是很棒的，但是对于jQuery Mobile框架来说这是一个小问题。
jQuery Mobile uses AJAX to load the contents of each page rather than reload the entire DOM structure. The
$(document).ready()function only runs once per page load, not per AJAX call. In jQuery Mobile, the
$(document).ready()function doesn’t run once per page, but rather once per site unless a page refresh is requested or performed by the user. This means that some of the default settings that need to be set by jQuery Mobile cannot be set in the
$(document).ready()function because they would not be applied to pages included through AJAX. The answer to setting and changing these defaults is to use the mobileinit event because it runs before the
$(document).ready()function ever does. To use the mobileinit event you must first include the jQuery framework and then either inline or include an external JavaScript file that contains an event binding for the mobileinit event and finally the include for jQuery Mobile.
jQuery Mobile使用AJAX加载每个页面的内容，而不是重新加载整个DOM结构。
$(document).ready()函数每个页面加载仅运行一次，而不是每个AJAX调用运行一次。 在jQuery Mobile中，
$(document).ready()函数不是每个页面运行一次，而是每个站点运行一次，除非用户请求或执行页面刷新。 这意味着jQuery Mobile需要设置的一些默认设置无法在
$(document).ready()函数中设置，因为它们不会应用于AJAX包含的页面。 设置和更改这些默认值的答案是使用mobileinit事件，因为该事件在
$(document).ready()函数之前运行。 要使用mobileinit事件，您必须首先包含jQuery框架，然后内联或包含一个外部JavaScript文件，该文件包含mobileinit事件的事件绑定，最后包含jQuery Mobile的include。
Example 3: Including jQuery, an Inline mobileinit Script, and jQuery Mobile

<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script type="text/javascript">
$(document).on("mobileinit", function() {
$.extend( $.mobile , {
pageLoadErrorMessage: 'Either the page cannot be found or it cannot be loaded.'
});
});
</script>
<script src="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.js"></script><script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>

$(document).on("mobileinit", function() {
$.extend( $.mobile , {
pageLoadErrorMessage: 'Either the page cannot be found or it cannot be loaded.'
});
});
</script>

[/code]JQUERY移动中的页面初始化 (PAGE INITIALIZATION IN JQUERY MOBILE)
To use the pageinit event on your page, you have to take a slightly less dynamic and more planned approach to your code. There are a few different ways you can attach the pageinit event in your code. When using a version of jQuery Mobile prior to 1.1, you will be using jQuery 1.6.4, which means you use the
.bind()function instead of the
.on()function. When using jQuery Mobile 1.1+ you use the
.on()function to bind the event. The
.on()function introduced in jQuery 1.7 is a unification of previous functions used to bind events. Instead of having to worry about using
.bind(),.live(), or
.delegate(), you can now use the
.on()function to find events. More about this function can be found by visiting http://api.jquery.com/on/. If you are using a version of jQuery Mobile prior to 1.1, you should not use the .on() method, but should instead use the
.delegate()or
.live()function.
要在页面上使用pageinit事件，您必须对代码采取稍微不那么动态且计划更多的方法。 您可以通过几种不同的方式在代码中附加pageinit事件。 当使用1.1之前的jQuery Mobile版本时，将使用jQuery 1.6.4，这意味着您使用
.bind()函数而不是
.on()函数。 使用jQuery Mobile 1.1+时，您可以使用
.on()函数绑定事件。 jQuery 1.7中引入的
.on()函数是用于绑定事件的先前函数的统一。 现在，您不必担心使用
.bind(),.live()
.delegate()或
.delegate()，而可以使用
.on()函数查找事件。 有关此功能的更多信息，请访问http://api.jquery.com/on/。 如果您使用的是1.1之前的jQuery Mobile版本，则不应使用.on()方法，而应使用
.delegate()或
.live()函数。

[/code]页面转换 (PAGE TRANSITIONS)
Page transitions involve two pages: a “from” page and a “to” page – these transitions animate the change from the current active page (fromPage) to a new page (toPage).
页面转换涉及两个页面：“从”页面和“至”页面–这些转换使从当前活动页面(fromPage)到新页面(toPage)的更改具有动画效果。
页面隐藏和显示事件 (PAGE HIDE AND SHOW EVENTS)
Because of its asynchronous nature, jQuery Mobile makes the distinction between page load events and page show and hide events. Page load events happen when a file is loaded into the browser in a standard synchronous way. When a file is loaded like this, the usual jQuery(document).ready() method is available for use, and jQuery Mobile also fires off other initialization events as well. As we have seen, a single HTML file may contain multiple jQuery Mobile page views, and the user can transition between those page views multiple times. These transitions do not fire off the page load events, instead jQuery Mobile provides a set of events that happen every time a page transition occurs. Each of these events provides references to the event and ui objects: pagebeforehide This event fires on the page being transitioned from, before the transition starts. ui.nextPage will be either the page being transitioned to, or an empty jQuery object if there is none. pagebeforeshow This event fires on the page being transitioned to, before the transition starts. ui.prevPage will be the page being transitioned from, or an empty jQuery object if there is none. pagehide This event fires on the page being transitioned from, after the transition finishes. ui.nextPage will be the jQuery object of the page being transitioned to, or empty if it does not exist. pageshow This event fires on the page being transitioned to, after the transition finishes. ui.prevPage will contain the jQuery object of the page being transitioned from, or empty if it does not exist. These four events provide useful analogs to the jQuery(document).ready() call for application page views. To use these events, you attach event listeners to the appropriate page using jQuery.bind(), jQuery.live(), or jQuery.delegate().
由于其异步特性，jQuery Mobile区分了页面加载事件与页面显示和隐藏事件。 以标准同步方式将文件加载到浏览器时，将发生页面加载事件。 当这样加载文件时，可以使用常规的jQuery(document).ready()方法，并且jQuery Mobile也会触发其他初始化事件。 如我们所见，单个HTML文件可能包含多个jQuery Mobile页面视图，并且用户可以在这些页面视图之间多次转换。 这些转换不会触发页面加载事件，而是jQuery Mobile提供了一组在每次页面转换发生时发生的事件。 这些事件中的每一个都提供对事件和ui对象的引用： pagebeforehide在转换开始之前，此事件在被转换的页面上触发。 ui.nextPage将是要转换到的页面，如果没有，则为空jQuery对象。 pagebeforeshow在转换开始之前，此事件在要转换的页面上触发。 ui.prevPage将是要转换的页面，如果没有，则为空的jQuery对象。 pagehide在转换完成后，此事件在要转换的页面上触发。 ui.nextPage将是要转换到的页面的jQuery对象，如果不存在则为空。 pageshow转换完成后，将在要转换的页面上触发此事件。 ui.prevPage将包含要转换的页面的jQuery对象，如果不存在则为空。 这四个事件为应用程序页面视图的jQuery(document).ready()调用提供了有用的类比。 要使用这些事件，请使用jQuery.bind()，jQuery.live()或jQuery.delegate()将事件侦听器附加到适当的页面。
jQuery.bind(), jQuery.live(), and jQuery.delegate() are the different methods that jQuery has for binding handlers to event listeners. For more details, consult the jQuery documentation. Here we are using jQuery.bind():
jQuery.bind()，jQuery.live()和jQuery.delegate()是jQuery用于将处理程序绑定到事件侦听器的不同方法。 有关更多详细信息，请查阅jQuery文档。 在这里，我们使用jQuery.bind() ：
<script>
$("#page1").bind("pagehide", function(event, ui) {
var strAlert = "";
for (var thing in event) {
strAlert += thing + " : " + event[thing] + "\n";
}
alert(strAlert);
});
</script><script>
$("#page1").bind("pagehide", function(event, ui) {
var strAlert = "";
for (var thing in event) {
strAlert += thing + " : " + event[thing] + "\n";
}
alert(strAlert);
});
</script>
[/code]For pages that are all contained within the same document, jQuery.bind() is sufficient. For pages that will be asynchronously loaded by jQuery Mobile, use jQuery.delegate() or jQuery.live().
对于全部包含在同一文档中的页面， jQuery.bind()就足够了。 对于将由jQuery Mobile异步加载的页面，请使用jQuery.delegate()或jQuery.live() 。

JQUERY移动负载事件 (JQUERY MOBILE LOAD EVENTS)
Page load events are for external pages. Whenever an external page is loaded into the DOM, 2 events fire. The first is
pagecontainerbeforeload, and the second will either be
pagecontainerload (success)or
pagecontainerloadfailed (fail). These events are explained in the table below:
页面加载事件是针对外部页面的。 每当将外部页面加载到DOM中时，就会触发2个事件。 第一个是
pagecontainerbeforeload，第二个将是
pagecontainerload (success)或
pagecontainerloadfailed (fail)。 下表说明了这些事件：
| Event | Description |
|---|---|
| pagecontainerbeforeload | Triggered before any page load request is made |
| pagecontainerload | Triggered after the page has been successfully loaded and inserted into the DOM |
| pagecontainerloadfailed | Triggered if the page load request fails. By default, it will show the “Error Loading Page” message |
| 事件 | 描述 |
|---|---|
| pagecontainerbeforeload | 在发出任何页面加载请求之前触发 |
| pagecontainerload | 成功加载页面并将其插入DOM后触发 |
| pagecontainerloadfailed | 如果页面加载请求失败，则触发。 默认情况下，它将显示“错误加载页面”消息 |
