how can I make jquery mobile "pagebeforeshow" event fire every time, not just on refresh
提问by Finglish
I have a jquery mobile page that uses the following code to hide a button when the page is accessed.
我有一个 jquery 移动页面，它使用以下代码在访问页面时隐藏按钮。
$('div:jqmData(role="page")').live('pagebeforeshow',function(){
$("#apply_btn").hide()
});
My problem is that the event only fires when the page is refreshed and not when arriving at the page from somewhere else in the site.
我的问题是该事件仅在页面刷新时触发，而不是在从站点的其他地方到达页面时触发。
I have tried using the "pageshow" event and the "pageinit" event but it still only fires when the page is refreshed.
我曾尝试使用“pageshow”事件和“pageinit”事件，但它仍然只在页面刷新时触发。

Just to remember that live method has been removed from jQuery 1.9. You should use from now on the onmethod:
请记住，实时方法已从 jQuery 1.9 中删除。从现在开始，您应该使用on方法：
$( '#yourPage' ).on( 'pagebeforeshow',function(event){
$("#uniqueButtonId").hide();
});

Have a look at http://jquerymobile.com/demos/1.1.0/docs/api/events.html
看看http://jquerymobile.com/demos/1.1.0/docs/api/events.html
This is the syntax:
这是语法：
$( '#yourPage' ).live( 'pagebeforeshow',function(event){
$("#uniqueButtonId").hide();
});
Good Luck

Strangely enough the short version doesn't work for me:
奇怪的是，简短版本对我不起作用：
$( '#yourPage' ).on( 'pagebeforeshow',function(event){
$('#uniqueButtonId').hide();
});
but I have to use:
但我必须使用：
$(document).on( 'pagebeforeshow' , '#yourPage' ,function(event){
$('#uniqueButtonId').hide();
});
