具体步骤

  1. 在 [Blogroot]\themes\butterfly\layout\includes\third-party\ 目录下新建 galmenu.pug 文件，注意缩进。

    #rightMenu
      each MenuItem,index in theme.GalMenu.MenuGuoup
        .rightMenu-group
          each item in MenuItem.MenuItem
            a.rightMenu-item.faa-parent.animated-hover(href=url_for(item.link),title=item.name,id=item.id)
              i.fa.faa-tada(class=item.icon)
              if index != 0
                span.rightMenu-name=item.name

  2. 修改 [Blogroot]\themes\butterfly\layout\includes\additional-js.pug 文件，在末尾添加内容（注意缩进）, 注意 butterfly_v3.6.0 取消了缓存配置，转为完全默认，需要将 {cache:theme.fragment_cache} 改为 {cache: true}：

    7
          if theme.pjax.enable
            !=partial('includes/third-party/pjax', {}, {cache:theme.fragment_cache})

          !=partial('includes/third-party/baidu_push', {}, {cache:theme.fragment_cache})

    +     if theme.GalMenu.enable
    +       !=partial('includes/third-party/galmenu', {}, {cache:theme.fragment_cache})

  3. 在 [Blogroot]\themes\butterfly\source\css\layout\ 目录下新建 galmenu.styl 文件。此处开头是默认图标配置。可以在配置项里更换自己喜欢的图标。

    /* rightMenu */
    #rightMenu {
        display: none;
        position: fixed;
        width: 160px;
        height: fit-content;
        top: 10%;
        left: 10%;
        background-color: var(--card-bg);

            }

            i {

            }
        }
    }

    .rightMenu-group.hide {
        display: none;
    }

  4. 新建 [Blogroot]\themes\butterfly\source\js\custom\index.js , 监听鼠标右键事件:

    let cyan = {};
    cyan.showRightMenu = function (isTrue, x = 0, y = 0) {
        let $rightMenu = $('#rightMenu');
        $rightMenu.css('top', x + 'px').css('left', y + 'px');

        if (isTrue) {
            $rightMenu.show();
        } else {
            $rightMenu.hide();
        }
    }
    // 右键菜单事件
    if (!(navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i))) {
        window.oncontextmenu = function (event) {
            $('.rightMenu-group.hide').hide();
            if (document.getSelection().toString()) {
                $('#menu-tools').show();
            }
            if (event.ctrlKey) return true;
            if (localStorage.getItem("right_menu_switch") === 'off') return true
            let pageX = event.clientX + 10;
            let pageY = event.clientY;
            let rmWidth = $('#rightMenu').width();
            let rmHeight = $('#rightMenu').height();
            if (pageX + rmWidth > window.innerWidth) {
                pageX -= rmWidth + 10;
            }
            if (pageY + rmHeight > window.innerHeight) {
                pageY -= pageY + rmHeight - window.innerHeight;
            }



            cyan.showRightMenu(true, pageY, pageX);
            return false;
        };

        window.addEventListener('click', function () { cyan.showRightMenu(false); });
    }
