mobile-pagecontainer:不起作用 [英] mobile-pagecontainer: not working

问题描述

$(":mobile-pagecontainer")不起作用.我必须使用$(document). 以下代码有什么问题吗?

$(":mobile-pagecontainer") is not working. I have to use $(document). Anything wrong with the following code?

    <div data-role="page" id="page1">

        <div data-role="header" >
            <h1>Page 1</h1>
        </div>

        <div role="main" class="ui-content">
            This is Page1.

            <a id="gotoPage2" href="#page2" class="ui-btn ui-corner-all ui-shadow ui-btn-a">Go to Page 2</a>

            <script>

            // not working
            $( ":mobile-pagecontainer").on( "pagecontainerhide", function( event, ui ) {
                alert( "page hide ");
            });

            // working
            $( document).on( "pagecontainerhide", function( event, ui ) {
                alert( "page hide " );
            });
           </script>
         </div>
    </page>

    <page  data-role="page" id="page2">
         ....
    </page>

但是它可以按以下方式更改页面:

But it works for changing page as followings:

$(":mobile-pagecontainer").pagecontainer("change", "#page2", { } );

谢谢.

推荐答案

$(":mobile-pagecontainer") 是指向内部或外部所有页面的包装.默认情况下，body是:mobile-pagecontainer，而.pagecontainer()是用于发出jQuery Mobile的特殊事件并用于导航的小部件.

$(":mobile-pagecontainer") is a selector that refers to wrapper of all pages, internal or external. By default body is :mobile-pagecontainer and .pagecontainer() is a widget used to emit jQuery Mobile's special events and used for navigation.

jQuery Mobile事件起泡到document，因此您可以用来捕获这些事件.

jQuery Mobile events bubble up to document so you can use to capture those events.

$(document).on("pagecontainershow", function (e, data) {
  console.log(data.toPage); /* current active page */
  console.log(data.prevPage); /* previous page */
});

如果要将事件附加到 pageconatiner ，则必须将它们包装在.ready()中才能使它们起作用.

If you want to attach events to pageconatiner, you have to wrap them in .ready() in order to make them work.

$(function () {
   $(":mobile-pagecontainer").on("pagecontainerhide", function (e, data) {
      console.log(data.toPage); /* page navigating to */
      console.log(data.prevPage); /* page that was just hidden */
   });
});

还可以使用窗口小部件.pagecontainer().

It is possible also to use the widget .pagecontainer().

$(":mobile-pagecontainer").pagecontainer({
    hide: function (e, data) {
             /* code */
          },
    show: function (e, data) {
             /* code */
          }
});
