"$(document).on('pageshow'"不使用jQuery 1.9.1 + JQM 1.3.0-stable

Question

使用jQuery 1.8.3

<!DOCTYPE html>
<html>
    <head>
        <script src="js/jquery-1.8.3.min.js"></script>
        <script src="js/jquery.mobile-1.3.0.min.js"></script>
        <script>
      $.support.cors = true;
      $.mobile.allowCrossDomainPages = true;

      $("#home").live("pageshow", function( event ) {
        alert( "Ok. This is Home!" );
      });
        </script>
    </head>
    <body>

    <!--- HOME --->
    <div data-role="page" id="home">
    <h2>Hello World</h2>
    </div>
    </body>
</html>

警报工作正常.

但是,使用jQuery 1.9.1(请注意我更改了版本,并使用"on"更改为"live".

<!DOCTYPE html>
<html>
    <head>
        <script src="js/jquery-1.9.1.min.js"></script>
        <script src="js/jquery.mobile-1.3.0.min.js"></script>
        <script>
      $.support.cors = true;
      $.mobile.allowCrossDomainPages = true;

      $("#home").on("pageshow", function( event ) {
        alert( "Ok. This is Home!" );
      });
        </script>
    </head>
    <body>

    <!--- HOME --->
    <div data-role="page" id="home">
    <h2>Hello World</h2>
    </div>
    </body>
</html>

警报不起作用.我确定我做错了什么.我一直在读jQuery Mobile 1.3.0-stable会使用jQuery 1.9.1,但也许我错了.

Answer 1

更改

 $("#home").on("pageshow", function( event ) {

至

  $(document).on("pageshow", "#home", function( event ) {

语法on与以下内容不同live:在进行绑定时,接收和委托事件的元素必须存在.
