c# - MongoDB, trying to import json which has been serialized using TypeNameHandling.Objects -


i'm receiving error trying import json mongodb.

2016-01-15t14:57:09.682-0800 error inserting documents: document can't have $ prefixed field names: $type

the json serialized using json.net

 var settings = new jsonserializersettings(); settings.typenamehandling = typenamehandling.objects; string output = jsonconvert.serializeobject(o, formatting.indented, settings);

see mongodb documentation talks restrictions on field names.

field names cannot contain dots (i.e. .) or null characters, , must  not start dollar sign (i.e. $).

if using mongo shell import you'll have change $type else.

alternately, use c# driver import documents , handle serializing concrete type name automatically.

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; } ...
