刚刚显示了哪一页? [英] Which page was just shown?

问题描述

在1.4.2中，我有这个:

In 1.4.2, I have this:

$(document).on('pagecontainershow', PageShown);

function PageShown(myEvent, myUI ) {
    log(this)
    log(myEvent)
    log(myUI)
};

我无法确定只显示了哪个页面. 如果我为选择器添加更多特异性，则不会触发该事件.

I can't determine which page was just shown. If I add more specificity to the selector, the event doesn't fire.

推荐答案

更新

从jQuery Mobile 1.4.2开始，您可以访问上一页.prevPage和下一页.toPage.

$(document).on("pagecontainerhide", function (e, ui) {
  var activePage   = ui.toPage,
      previousPage = ui.prevPage;
});

两者都是jQuery对象，因此不需要$().

Both are jQuery objects so $() isn't needed.

要确定当前哪个页面处于活动状态，您有两个选择:

To determine which page is currently active, you have two options:

1. 听pagecontainerhide并检查该事件发出的ui.nextPage对象

1. Listen to pagecontainerhide and check ui.nextPage object emitted by that event

$(document).on("pagecontainerhide", function (e, ui) {
  var activePage = $(ui.nextPage);
});

在pagecontainershow上，使用以下函数将返回活动页面.

On pagecontainershow, use the below function which will return active page.

var activePage = $.mobile.pageContainer.pagecontainer("getActivePage");
