问题描述

在此项目中使用jquery和phonegap

in this project im using jquery and phonegap

我有一个链接,如果点击,更改页面:

i have a link that if clicked , changes the page:

$('#statsButtonmain').on('click', function() {
        $.mobile.changePage("stats.html", { transition: "slideup"}, true, true);  
});

这很好,但我想运行一个函数( playMusic )),如下所示:

this works fine, but i would like to run a function (playMusic()) when the transition is done, something like this:

$('#statsButtonmain').on('click', function() {
        $.mobile.changePage("stats.html", { transition: "slideup"}, true, true);  
            playMusic();
});

我发现有一个 pageshow

这似乎不起作用,任何想法?

this doesn't seem to work, any ideas?

感谢

推荐答案

开发,因此这可能不是最有效的解决方案。正如你所说, pagehow 事件是你需要使用的。这里是我在本地运行的2个HTML文件,其中在 stats.html 页面转换完成后看到警报。 .live()绑定到 #stats 元素的页面 pageshow event。

I've not done a lot a jQuery mobile development so this might not be the most efficient solution. As you said, the pageshow event is what you need to use. Here are the 2 HTML files I ran locally in which I see the alert after the stats.html page transition is completed. The .live() is bound to the #stats element's page pageshow event.

(另存为index.html)

(saved as index.html)

<!doctype html> 
<html> 
  <head> 
    <title>Home</title> 
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no"/>
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.css" />
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
    <script type="text/javascript" src="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.js"></script>
    <script type="text/javascript">
    $(document).ready(function() {
        $('#statsButtonmain').on('click', function() {
           $.mobile.changePage('stats.html', { transition: 'slideup'}, true, true);  
        });

        $('#stats').live('pageshow', function(event, ui) {
          playMusic();
        });

        function playMusic() {
          alert('playing music');
        }
    });
    </script>
</head> 
<body>
<div data-role="page" id="home">
    <div data-role="header">
       <h1>Callback test</h1>
    </div>
    <div data-role="content">
      <a href="#" id="statsButtonmain">click me</a>
    </div>
</div>
</body>
</html>

(另存为stats.html)

(saved as stats.html)

<!doctype html> 
<html> 
  <head> 
    <title>Stats</title> 
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no"/>
