问题
I'm building my first JQM site so I think I'm missing some simple little thing that's causing me a bunch of problems.
I have setup the page, header, content and footer and a panel for the menu. Then I have I have a js file with the following:
$(document).on('pageinit', function (event) {
alert('this works every time you navigate to another page');
$("#menu-panel").panel("open");//this works the first time only
$("#new-lump-sum").popup("open");//this never works
});
Can anyone tell me why I'm getting this behaviour instead of both the panel and the popup opening every time you navigate to another page?
I also can't open them programmatically from the browser console (using chrome)

回答1:
Popups and dialogs are tricky when it comes to opening them right after a page event occurs. To fix this issue, you need to use setTimeout to open a dialog or a popup.
$(document).on('pageinit', function() {
setTimeout(function () {
$('#new-lump-sum').popup('open');
}, 100); // delay above zero
});
