i don't have sufficient points comment, answering here.

from understand, when click on map text enter on prompt should displayed when click on marker gets created. here's fiddle - http://jsfiddle.net/pn992yy4/31/. message enter in prompt displayed on marker's info window when click on it.

basically, modified addmarker function call function called attachnote takes in parameters marker , message entered in prompt dialog. addmarker function attaches message provided marker's info window.

function attachnote(marker, note) {    var infowindow = new google.maps.infowindow({         content: note    });     marker.addlistener('click', function() {        infowindow.open(marker.get('map'), marker);    }); }

the addmarker function call on click event should have poznamka.

addmarker(event.latlng, map, poznamka);

hope answer helps. let me know if not.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

(and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
