javascript - How to save multiple checkbox values to local storage? -


i'm trying save multiple check boxes in local storage, see code below , idea.

what have tried far: 

$(function () { var data = localstorage.getitem("favorite");  if (data !== null) {     $("input[name='favorites']").attr("checked", "checked"); } }); $("input[name='favorites']").click(function () {  if ($(this).is(":checked")) {     localstorage.setitem("favorite", $(this).val()); } else {     localstorage.removeitem("favorite"); } });

html

<input type="checkbox" class="fachkrnd" name="favorite1" id="like"> <input type="checkbox" class="fachkrnd" name="favorite2" id="like1"> <input type="checkbox" class="fachkrnd" name="favorite3" id="like2">

simply serialize them.

$('.fachkrnd').on('click', function() {     var fav, favs = [];     $('.fachkrnd').each(function() { // run through each of checkboxes         fav = {id: $(this).attr('id'), value: $(this).prop('checked')};         favs.push(fav);     }     localstorage.setitem("favorites", json.stringify(favs)); });

they saved in json so:

"[{\"id\": \"like\", \"value\": true},{\"id\": \"like2\", \"value\": true},{\"id\": \"like3\", \"value\": true}]"

which can later load:

var favorites = json.parse(localstorage.getitem('favorites'));

and loop through reassign:

for (var i=0; i<favorites.length; i++) {     $('#' + favorites[i].id ).prop('checked', favorites[i].value); }

here's working fiddle. can check box, , refresh see values loaded.

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; } ...
