slide.js
$(document).on('pagebeforecreate', function() {
$('#article1').bind('swipeleft', function(event,ui)
{
$.mobile.changePage("swipepage2.html", "slide");
});
$('#article2').bind('swipeleft', function(event,ui)
{
$.mobile.changePage("swipepage3.html","slide");
});
$('#article2').bind('swiperight', function()
{
$.mobile.changePage("swipepage1.html","slide");
});
$('#article3').bind('swiperight', function(event,ui)
{
$.mobile.changePage("swipepage2.html","slide");
});
});
推荐答案
这是因为事件为页面绑定了两次.
This is because the events are getting bind twice for the page.
1.建议使用.on()代替.bind() 我在pagecreate/init/show之外使用它，而.on没有遇到任何问题. 例如.
1.It is recommended to use .on() instead of .bind() I am using it outside of pagecreate/init/show and I am not facing any issues with .on eg.
$('#article1').on('swipeleft', function(event,ui)
{
$.mobile.changePage("swipepage2.html", "slide");
});
