mongodb - find the document from sub array? -


i have collection documents this:

"awards" : {     "oscars" : [         {"award": "bestanimatedfeature", "result": "won"},         {"award": "bestmusic", "result": "won"},         {"award": "bestpicture", "result": "nominated"},         {"award": "bestsoundediting", "result": "nominated"},         {"award": "bestscreenplay", "result": "nominated"}     ],     "wins" : 56,     "nominations" : 86,     "text" : "won 2 oscars. 56 wins , 86 nominations." }

what query document use in find() command return movies in my_collection collection either won or nominated best picture?

you need use dot notation specify exact match on embedded document , use $in operator select documents won or nominated best picture

you shouldn't use $or operator here because perform collection scan if not clauses supported indexes mention in documentation.

db.my_collection.find({      'awards.oscars.award': 'bestpicture',      'awards.oscars.result': { '$in': [ 'won', 'nominated' ] }  } )

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; } &l
