Using sessionstorage for saving dark mode

问题

I successfully added dark mode to my site using This fiddle

JS:

$('#mode').change(function(){   

if ($(this).prop('checked'))
{
    $('body').addClass('dark-mode');
}
else
{
    $('body').removeClass('dark-mode');
}
});

However, when refreshing the page the theme switches back obviously. I can't find out how to use sessionstorage to keep dark mode over the domain.

Can someone help me? Thanks!

You can use local storage for storing the data

function darkmode(){
    $('body').addClass('dark-mode');
    localStorage.setItem("mode", "dark");
    }



function nodark(){
        $('body').removeClass('dark-mode');
        localStorage.setItem("mode", "light");
        }

  if(localStorage.getItem("mode")=="dark")
        darkmode();
  else
    nodark();

$('#mode').change(function(){   

    if ($(this).prop('checked'))
    {
        darkmode();
    }
    else
    {
        nodark();
    }

});
