javascript - Keep toggle and add class active with JQuery through pages refresh -


i used onclick function , when click functions addclass , toggle events added function. once when activate toggle , addclass , refresh page addclass getting removed , toggle events running beginning. how avoid the removal of class , toggle function on page reload?

    jqry("#wrap").delegate('img.favourite', 'click', function() {        var toggle = $(this).data("toggleflag") || false;       var check_fav = jqry(this).hasclass('switcher-active');       var id = jqry(this).attr('pid');       if (!toggle && !check_fav) {         jqry(this).addclass('switcher-active');         alert("test1");       } else {         jqry(this).removeclass('switcher-active');         alert("test2");       }       $(this).data("toggleflag", !toggle);     });       <img class="favourite"  src="images/fav.png" alt="favourite" >

the above code not working properly. getting addclass('switcher-active') active , getting alert test1 on first click , removeclass('switcher-active') , alert test2 on second click. when refresh page after first click i.e after addclass('switcher-active') active must continue removeclass('switcher-active') , alert test2. on page refresh addclass('switcher-active') inactive , alerted test1. how test2 , removeclass('switcher-active') after page refresh. how possible?
