jQuery Mobile - 绑定到 pageinit 事件
我试图理解以下 jQuery Mobile 示例。
$( '#aboutPage' ).live( 'pageinit',function(event){
alert( 'This page was just enhanced by jQuery Mobile!' );
});
在这种情况下，#aboutPage 是什么？ pageinit 绑定到的对象是什么？
I am trying to understand the following jQuery Mobile example.
$( '#aboutPage' ).live( 'pageinit',function(event){
alert( 'This page was just enhanced by jQuery Mobile!' );
});
What is #aboutPage in this context? What is the object pageinit is binding to?

aboutPage应该是页面的 id。（iediv 与data-role="page"）。live()附加您拥有的功能定义其中包含对aboutPage的pageinit事件的警报。当页面被打开时，会在页面上触发pageinit已初始化。简而言之，您的代码的作用是
即使页面不在视图中，也可能会被初始化。因此，即使在您进入该页面之前，该页面的
pageinitdiv 将被触发。如果您正在加载另一个 html 文件作为新页面pageinit，则仅当您将该页面加载到视图中时才会触发该页面。所以，在您的情况下，如果您想做某事当你的 div 进入视图时，你可以尝试pagebeforeshow和pageshow。pagebeforeshow将在动画开始前在新页面上触发，pageshow在动画结束后触发。aboutPageshould be the id of the page.(i.e.div withdata-role="page").live()attaches the funcion you have defined which contains thealertto thepageinitevent ofaboutPage.pageinitis triggered on a page when the page is initialized.So in short What your code does is
The page might be initialized even if it is not in view.So even before you go to that page,the
pageinitof the div will be triggered.If you are loading another html file as the new pagepageinitfor that page will be triggered only when you load that page into view.So,in your case if you want to do something when your div comes into view,you can try thepagebeforeshowandpageshow.pagebeforeshowwill be triggered on the new page before animation starts andpageshowafter animation is over.
