What is the "mobile-pagecontainer" selector
提问by Lordbalmon
jQuery Mobile has various events and methods. The pagecontainerevents and methods are used to handle most of the pageevents from v1.4. I do not understand the use of the :mobile-pagecontainerselector.
jQuery Mobile 有各种事件和方法。该pagecontainer事件和方法来处理大部分的page从事件v1.4。我不明白:mobile-pagecontainer选择器的使用。
The API documentation only uses $('.selector')which is straightforward and simple to understand though, I do not know which object it is referring to. Am I supposed to use it on a $('div[data-role="page"]')or on $('body'). And what does the other selector, :mobile-pagecontainer, signify?
API 文档只使用了$('.selector')简单易懂的内容,我不知道它指的是哪个对象。我应该在 a$('div[data-role="page"]')或 on 上使用它吗$('body')?另一个选择器:mobile-pagecontainer, 表示什么?
API: jQuery 1.4.0 API

Edit: Also, I found many examples on stackoverflow and other websites using $(document)what is the relation to all these?

$(":mobile-pagecontainer")is a selector, it refers to the parentelement of jQM pages, both internalpages and externalones.
$(":mobile-pagecontainer")是一个选择器,它指的是jQM页面的父元素,包括内部页面和外部页面。
By default, :mobile-pagecontaineris body. It also can be referred to as $.mobile.pageContainer(mind capital "C" in pageContainer).
默认情况下,:mobile-pagecontainer是body。它也可以称为$.mobile.pageContainer(pageContainer 中的记大写“C”)。
.pagecontainer()is a function that is used to changeand loadpages, as well as retrieve active page.
.pagecontainer()是一个函数,用于更改和加载页面,以及检索活动页面。
In short, $(":mobile-pagecontainer")= $.mobile.pageContainer= $("body")(default).
总之,$(":mobile-pagecontainer")= $.mobile.pageContainer= $("body")(默认)。
The value of :mobile-pagecontainercan be overridden on mobileinit, in case you want to wrap pages in a different element than body.
的值:mobile-pagecontainer可以被覆盖mobileinit,以防您想用与 不同的元素包装页面body。
$(document).on("mobileinit", function () {
$.mobile.pageContainer = $("#foo");
});
To change pages (assuming
foois the container):$("#foo").pagecontainer("change", "#pageID or URL");To load an externalpage:
$("#foo").pagecontainer("load", "URL");To retrieve active page:
$("#foo").pagecontainer("getActivePage");
要更改页面(假设
foo是容器):$("#foo").pagecontainer("change", "#pageID or URL");加载外部页面:
$("#foo").pagecontainer("load", "URL");检索活动页面:
$("#foo").pagecontainer("getActivePage");
