javascript - How to remember current toggle state in this example after page refresh with local storage? -


i have 3 tabs: 'monday', 'tuesday' , 'favorites'. each tab contains boxes empty heart @ start ('.favorite i'). want save current toggle class after refresh.

toggle:

heartlink.find('i').toggleclass('fa-heart-o fa-heart'); // .selected or not

i've started with:

if (heartlink.find('i').hasclass('fa-heart-o')) {   localstorage.setitem('displayicon', 0);  } else {   localstorage.setitem('displayicon', 1);  }

and know need similar don't know how it..

to make clear: want save current state of each specific heart. don't 1 icon affect boxes.

var showicontoggle = localstorage.getitem('displayicon'); if (showicontoggle == 'true') {     // code }

html: 

   <section id="speakers-programme">      <div class="container">        <div class="tabs_main">            <div class="col-md-5"><a data-target="#mon" class="btn active" data-toggle="tab">monday</a></div>           <div class="col-md-5"><a data-target="#tue" class="btn active" data-toggle="tab">tuesday</a></div>           <div class="col-md-2"><a data-target="#fav" class="btn active" data-toggle="tab"><i class="fa fa-heart" aria-hidden="true"></i></a></div>         </div>         <div class="tab-content">           <div class="tab-pane active" id="mon">            <br>            <div class="spaces">              <div class="box-container">                <div class="box not-selected" id="box1">                <a href="#" class="favorite"><i class="fa fa-heart-o" aria-hidden="true"></i></a>              </div>             </div>             <div class="box-container">              <div class="box not-selected" id="box2">                <a href="#" class="favorite"><i class="fa fa-heart-o" aria-hidden="true"></i></a>              </div>             </div>          </div>          </div>          <div class="tab-pane active" id="tue">            <br>            <div class="spaces">            </div>         </div>          <div class="tab-pane active" id="fav">            <br>            <div class="spaces">            </div>         </div>           </div>      </div>   </section>

js:

$('div.tab-pane').on('click', '.favorite', function(e) {       e.preventdefault();          var heartlink = $(this);        //toggle font awesome on click       heartlink.find('i').toggleclass('fa-heart-o fa-heart'); // .selected or not, need 2 classes toggle.        if (heartlink.find('i').hasclass('fa-heart-o')) {         localstorage.setitem('displayicon', 0);       } else {         localstorage.setitem('displayicon', 1);       }   });  var showicontoggle = localstorage.getitem('displayicon');    if (showicontoggle == 'true') {      // code here }

fiddle: https://fiddle.jshell.net/itsfranhere/1q93a6x1/9/

this question folowing that one.

to save not cloned element states (favorited or not), add this:

at end of click handler, save classes clicked i.

// save current toggle state localstorage.setitem(box.attr("id"), $(this).find("i").attr("class")); console.log($(this).find("i").attr("class"));

on page load, before loading favorites localstorage, apply saved classes:

// load heart's element states $(".box").each(function(){   console.log( $(this).attr("id") );   console.log( localstorage.getitem($(this).attr("id")) );    if(localstorage.getitem($(this).attr("id")) != null){     $(this).find("i").removeclass().addclass( localstorage.getitem($(this).attr("id")) );   } });
