如何绑定事件"pageshow"使用JQuery Mobile获取外部HTML文件 [英] How to bind the event "pageshow" for an external HTML file with JQuery Mobile
问题描述
我正在使用JQuery Mobile(版本1.3.0)开发Web应用程序.如果一个HTML文件只有一个，则可以将"pageshow"事件绑定到页面div:
I´m developing a web app using JQuery Mobile (ver 1.3.0). If a have only one HTML file, I can bind the "pageshow" event to the page div:
<!DOCTYPE HTML>
<html>
<head>
<title>Funil de Vendas</title>
<meta http-equiv="Content-type" name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no, width=device-width">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="lib/jquery-1.8.2.min.js"></script>
<script src="lib/jquery.mobile-1.3.0.min.js"></script>
<script>
var nice = false;
$(document).ready( function(){
$("#other_page").bind('pageshow',function() {
alert('The page was called!');
});
});
</script>
</head>
<body>
<div data-role="page" class="Page" id="home_page">
<div data-role="content">
<a data-role="button" href="#other_page" data-inline="true" style="width:300px;">Iniciar</a>
</div>
</div>
</div>
<div data-role="page" class="Page" id="other_page">
<div data-role="content">
...
</div>
...
...
...
</div>
</body></html>
如何使用多个HTML文件执行相同的操作.我无法绑定到的页面，因为此div位于另一个HTML文件中.
How can I do the same using multiples HTML files. I cannot bind to the page the because this div is in another HTML file.
<div data-role="page" class="Page" id="home_page">
<div data-role="content">
<a data-role="button" href="other_page.html" data-inline="true" style="width:300px;">Iniciar</a>
</div>
</div>
提前谢谢！
推荐答案
这里有2种可能的方法:
There are 2 possible ways here:
第一个解决方案.如果您正在使用多个HTML文件，并且所有文件都以ajax加载(这是标准jQuery Mobile的页面加载方式).在这种情况下，必须将所有javascript都加载到第一个html文件中，因为jQM将仅加载其他html文件的BODY内容.
First solution. In case you are using multiple HTML files and all of them are loaded with an ajax (this is a standard jQuery Mobile way of page loading). In this case all of javascript must be loaded into the first html file, because jQM will load only BODY content of other html files.
index.html:
<!DOCTYPE html>
<html>
<head>
<title>jQM Complex Demo</title>
<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0"/>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="http://www.dragan-gaic.info/js/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
<script>
$(document).on('pagebeforeshow', '#index', function(){
alert('This is a first page!');
});
$(document).on('pagebeforeshow', '#second', function(){
alert('This is a second page!');
});
</script>
</head>
<body>
<div data-role="page" id="index" data-theme="b">
<div data-role="header" data-theme="a">
<h3>First page</h3>
</div>
<div data-role="content">
<a data-role="button" id="some-btn" href="second.html">Open next page</a>
</div>
<div data-theme="a" data-role="footer" data-position="fixed">
</div>
</div>
</body>
</html>
second.html:
<div data-role="page" id="second" data-theme="b">
<div data-role="header" data-theme="a">
<h3>Second page</h3>
</div>
<div data-role="content">
This is a second page
</div>
<div data-theme="a" data-role="footer" data-position="fixed">
</div>
</div>
第二个解决方案..如果您有多个HTML文件，但您的所有页面均已链接，且具有rel ="external"属性的链接或ajax在应用程序级别处于打开状态.在这种情况下，每个html页面都必须具有自己的HEAD和BODY.而且每个页面都必须有自己的javascript.
Second solution. In case you have multiple HTML files but all your pages are linked wit links having rel="external" attribute or ajax is turned of on app level. In this case every html page must have its own HEAD and BODY. And every page must have it own javascript.

});

</div>
<div data-theme="a" data-role="footer" data-position="fixed">

});
</script>

<div data-role="page" id="second" data-theme="b">

</div>
<div data-role="content">
This is a second page
</div>
<div data-theme="a" data-role="footer" data-position="fixed">
