JQueryMobile: pagecontainershow on a particular page not working - jquery-mobile

Question

JQueryMobile 1.4 has deprecated the pageshow event and instead recommends using pagecontainershow; however, while I'm able to get the pagecontainershow event at a document level, I can't bind a function to a particular page.
<div id="page1" data-role="page">
...
<script>
$( "#page1" ).on( "pagecontainershow", function( event, ui ) {
console.log("page1 pagecontainershow");
} );
</script>
</div>

I also considered using the alternative form of the jQuery "on" function where we use a selector, but that would need to be a parent of the page div, and that might include other pages, so that doesn't work.
As a workaround, I've done this, but it is very inefficient:
function registerOnPageShow(pageId, func) {
var strippedPageId = pageId.replace("#", "");
var e = "pagecontainershow." + strippedPageId;
// TODO why isn't it working to use $(pageId) instead of $(document)?
$( document ).off(e).on(e, null, {page: strippedPageId, f: func}, function(e, ui) {
if ($(":mobile-pagecontainer").pagecontainer("getActivePage")[0].id == e.data.page) {
e.data.f(e, ui);
}
});
}

Answer 1

You can get the page ID like this.
$(document).on('pagecontainershow', function(e, ui) {
var pageId = $('body').pagecontainer('getActivePage').prop('id');
});
There is currently no way to have a show/hide event on a specific page.

Answer 2

Here is what I'm using (jqmobile >1.4):
$(document).on("pagecontainershow", function () {
var activePage = $.mobile.pageContainer.pagecontainer("getActivePage");
var activePageId = activePage[0].id;
switch (activePageId) {
case 'loginPage':
...
break;
case 'homePage':
...
break;
case 'groupPage':
...
break;
default:
}
});

Answer 3

$(document).on("pagecontainershow", function(event, ui) {
var pageId = $('body').pagecontainer('getActivePage').prop('id'),
showFunc = pageId+'_show';
if (typeof MobileSite[showFunc] == 'function') {
MobileSite[showFunc]();
}
});
MobileSite is contained in an external .js file with all the show() functions.

Answer 4

$(document).on("pagecontainerbeforeshow", function (event, ui) {
if (typeof ui.toPage == "object") {
var crrentPage = ui.toPage.attr("id")
}
});
and you must use this code before calling Index.js !!
