问题描述
使用jQuery 1.8.3
Working with 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"更改了"live".
However, with jQuery 1.9.1 (please note that I changed the version and "live" with "on".
<!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>
警报将不起作用.我确定我做错了什么.我一直在阅读稳定的jQuery Mobile 1.3.0将使用jQuery 1.9.1，但也许我错了.
Alert won't work. I'm sure I'm doing something wrong. I've been reading that jQuery Mobile 1.3.0-stable would use jQuery 1.9.1, but perhaps I'm wrong.
推荐答案
更改
$("#home").on("pageshow", function( event ) {
到
$(document).on("pageshow", "#home", function( event ) {
on的语法与live的语法不同:进行绑定时，用于接收和委托事件的元素必须存在.
The syntax of on isn't the same than the one of live : the element that will receive and delegate the event must be existing when you make the binding.
