javascript - Chrome Extension : Adding rows to a table on occurrence of an event -


i have background script background.js pops html page popup.html has script time.js. content script monitors onbeforeunload event upon url stored(along other data). time.js script loads stored data , puts them in table.

background.js

chrome.browseraction.setpopup({popup:"popup.html"});

popup.html

<!doctype html> <html lang="en">   <body>     <div id='div'></div>     <table id="datatable"></table>     <script src="time.js"></script>   </body> </html>

time.js

loaddata(); function loaddata() {   chrome.storage.local.get(["hrs","mins","secs","urls"],                             function(result)                             {                              var row = document.createelement('tr');                              var col1 = document.createelement('td');                              var col2 = document.createelement('td');                              row.appendchild(col1);                              row.appendchild(col2);                              col1.innerhtml = result.urls;                              col2.innerhtml = result.hrs+":"+result.mins+":"+result.secs;                              document.getelementbyid("datatable").appendchild(row);                            }); }

however, popup.html able display 1 row(0th row, guess) every time click on browser action icon. want append rows existing table. have seen few posts talk creating , appending new rows, none of them worked. tried store rowid , increment upon event worked fine row=table.insertrow(rowid) gave same problem. want know why happening , possible solution it.

edit : think problem maybe due fact popup.html loads every time click on browser action button(resetting previous table). but, have included popup inside background script , background scripts start running in background of browser once extension loaded(one instance). think popup.html should behave same way , paragraph/table_row added must remain intact.

ps- i'm new chrome extensions , if i'm missing here, i'd learn.

your assumption correct. popup.html loads every time. not possible 'include in background'. did set url can accomplished in manifest.json

there no persistence, have store information somewhere , recreate whole table every time popup loads.

save information in localstorage, chrome.storage or myriad of other persistence engines available.

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, ...
