jquery mobile Popup on pageinit popupinit? - jquery-mobile

Question

Is there a way to use some pageinit event for a popup, in order to populate an input box with an email address from the main page?
So in my html, I have 1 page declared as data-role="page" and one popup declared as data-role="popup". In the "page" I have an input containing an email address, and a button that calls the popup. In the popup I have some text, another input text and 2 buttons. This input box must be populated with the contents of the main page input box value. How can I achieve that? Is there some pageinit event for popups too?
So here is my main page declaration (pg_main)
<div data-role="page" id="pg_main">
<input type="email" name="emailadr" is="emailadr" value="" />
<input id="sendemail" class="emailclass" type="button" name />
</div>
and now the popup (sendm)
<div data-role="popup" id="sendm" class="ui-content">
<h3>Send the email</h3>
<p> Confirm email address below</p>
<input type="email" name="adresa" id="adresa" value="" />
<input type="button" id="emailok" value="Send" />
<input type="button" id="emailno" value="Give up" />
</div>
Of course I have some code that fills the input in pg_main with a valid email address, but that is not my issue.
In my script, I call the popup like this:
$(document.body).on('click','.emailclass', function(){
$('#sendm').popup("open");
});
How can I fill the $('#adresa') from popup sendm with the value of $('#emailadr') from page pg_main?
Thank you

What you need is this code:
$("#sendm").on("popupafteropen", function( event, ui ) {
$('#adresa').val($('#emailadr').val());
});
It will be executed when popup is opened. Event used here is called popupafteropen and you can find more about it in an official documentation.
