javascript - How to protect array? -


i have problem site. have make website using this , laravel. so, using jquery plugin, have set "prices" array. , now, problem, how can protect prices? want "anti editing" developer console, how? maybe can "skip" javascript code? thank in advance.

you can lock object using object.freeze on it

var arr = [1, 2, 3]; // [1, 2, 3]  object.freeze(arr); // can't modify arr[1] = 100; // can't delete delete arr[1]; // can't add arr[3] = 4; // arr.push(5); // `throw` typeerror // same @ freeze time arr; // [1, 2, 3]

freezing doesn't flow down nested objects, if wish children frozen need iterate on properties of object too.

please note

  1. once frozen cannot unfreeze object.
  2. you should never assume data coming client has not been tampered with. validate server side.

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
