javascript - For Loop refusing to Loop; Works Perfectly Fine if Run Manually -


alright, so, simple enough question. i'm sure has simple , stupid not doing right. i'm building app program exercise routine can keep track of every week (and learn app development using cordova). within code, each time come exersetup screen want read saved exercise file, parse array of objects, convert objects exercise objects, display them on screen. have loop supposed check each element of array process information, display, repeat until has done each element in array. works fine first item, stops. if manually run loop multiple times, functions perfectly. not listed code function addrow(), adds row of formatted dropdown selectors input, increments rownum keep track of row operating on. guys can offer appreciated. if need submit more information happy so. here's loop in question:

edit: fixed things suggestions in comments below. code still functions same. works fine on first run through loop, stops. if continue run loop manually (declaring on , on again in console) works fine, not, reason, run "for" loop. i've included rest of function loop nested in, in case helps.

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; } ...

ruby on rails - Seeing duplicate requests handled with Unicorn -

recently upgraded our ec2 instances c3.large in order boost more unicorn workers handle increased traffic our site. (6xworkers per machine - 2 ec2 instances). when did this, started seeing duplicate records being created! looks somehow, maybe 2 unicorn workers attempting process same request? in nginx logs see 1 [post] request particular rails controller - yet 2 records being created in database. i'm hitting kind of race condition issue - have no idea how debug this. doesn't happen time, when it's frustrating well. noticed 2 database records within 5 seconds of each other. (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, ...
