javascript - 希望获得不断变化的 LocalStorage 值

Question

希望我能以一种有意义的方式解释我的问题。

我在单击按钮时更改 CSS 主题，当单击特定主题的按钮时，它会将该类名保存到 LocalStorage，但由于 LocalStorage 键和值不断变化，我只想调用任何单击后在 localstorage 中设置，而不是特定值。我正在使用 jQuery 进行按钮点击，我在下面包含了我的代码，我们将不胜感激任何帮助。

$(document).ready(function(){

    $('#dark').click(function(){
        $('#app-root').removeClass();
        $('#app-root').addClass('theme-dark');
        localStorage.clear();
        localStorage.setItem('theme-dark', ['theme-dark']);
        localStorage.getItem('theme-dark');
    });

    $('#light').click(function(){
        $('#app-root').removeClass();
        $('#app-root').addClass('theme-light');
        localStorage.clear();
        localStorage.setItem('theme-light', ['theme-light']);
        localStorage.getItem('theme-dark');
    });

    $('#beaker').click(function(){
        $('#app-root').removeClass();
        $('#app-root').addClass('theme-beaker');
        localStorage.clear();
        localStorage.setItem('theme-beaker', ['theme-beaker']);
        localStorage.getItem('theme-dark');
    });

    $('#outrun').click(function(){
        $('#app-root').removeClass();
        $('#app-root').addClass('theme-outrun');
        localStorage.clear();
        localStorage.setItem('theme-outrun', ['theme-outrun']);
        localStorage.getItem('theme-dark');
    });

    var localItem = localStorage.getItem('theme-outrun');

    $('body').addClass(localItem);

});

一键设置本地存储的不同主题

$(document).ready(function(){

    $('#dark').click(function(){
        $('#app-root').removeClass();
        $('#app-root').addClass('theme-dark');
        localStorage.clear();
        localStorage.setItem('theme', ['theme-dark']);
        localStorage.getItem('theme');
    });

    $('#light').click(function(){
        $('#app-root').removeClass();
        $('#app-root').addClass('theme-light');
        localStorage.clear();
        localStorage.setItem('theme', ['theme-light']);

    });

    $('#beaker').click(function(){
        $('#app-root').removeClass();
        $('#app-root').addClass('theme-beaker');
        localStorage.clear();
        localStorage.setItem('theme', ['theme-beaker']);
        localStorage.getItem('theme');
    });

    $('#outrun').click(function(){
        $('#app-root').removeClass();
        $('#app-root').addClass('theme-outrun');
        localStorage.clear();
        localStorage.setItem('theme', ['theme-outrun']);
        localStorage.getItem('theme');
