javascript - Keep CSS styles after navigating to another page -


i have jquery code navbar controls dropdown , other styling. testing purposes, i've made first line:

$( ".dropdown--link").on("click", function(event) {     event.preventdefault(); })

but stops link functioning. there way maintain jquery styling, , link new page while maintaining added style? example, styling after event.preventdefault(); removed after navigate new page , want remain (in case preventdefault removed).

( ".dropdown--link").on("click", function(event) {         // event.preventdefault();          var targetposition = $(this).offset().left;         var targetwidth = $(this).width();         var targetcenter = targetposition + (0.5 * targetwidth) - 10;          $( "nav ul li" ).each(function() { $(this).removeclass("bold"); });         $(this).addclass('bold');         $(".arrow-down").show();         $(".arrow-down").css("left", targetcenter); })

you can save "status" of style local storage , every time load page change style if changed previously.

function changestyle() {         // event.preventdefault();         localstorage.setitem("stylechanged", "1");          var targetposition = $(this).offset().left;         var targetwidth = $(this).width();         var targetcenter = targetposition + (0.5 * targetwidth) - 10;          $( "nav ul li" ).each(function() { $(this).removeclass("bold"); });         $(this).addclass('bold');         $(".arrow-down").show();         $(".arrow-down").css("left", targetcenter); }  $(".dropdown--link").on("click", changestyle);  $.ready(function(){     var stylechanged = localstorage.getitem("stylechanged");     if (stylechanged && stylechanged.equals("1")) {         changestyle();     } });

when you'll want undo change run code:

localstorage.setitem("stylechanged", "0");
