html - 让 MDC 抽屉出现在顶部应用栏下方

问题描述

我按照此处的示例代码 将可关闭的抽屉放在顶部应用程序栏下，但它不起作用。

这是我尝试过的：

// Note: these styles do not account for any paddings/margins that you may need.
body {
  display: flex;
  height: 100vh;
}

.mdc-drawer-app-content {
  flex: auto;
  overflow: auto;
  position: relative;
}

.main-content {
  overflow: auto;
  height: 100%;
}

.app-bar {
  position: absolute;
}

// only apply this style if below top app bar
.mdc-top-app-bar {
  z-index: 7;
}

解决方案

为了在可解雇抽屉的一侧有标题，您需要以下结构：

// Instantiate MDC Drawer
const drawerEl = document.querySelector('.mdc-drawer');
const drawer = new mdc.drawer.MDCDrawer.attachTo(drawerEl);

// Instantiate MDC Top App Bar (required)
const topAppBarEl = document.querySelector('.mdc-top-app-bar');
const topAppBar = new mdc.topAppBar.MDCTopAppBar.attachTo(topAppBarEl);

topAppBar.setScrollTarget(document.querySelector('.main-content'));
topAppBar.listen('MDCTopAppBar:nav', () => {
  drawer.open = !drawer.open;
});
// Note: these styles do not account for any paddings/margins that you may need.
body {
  display: flex;
  height: 100vh;
}

.mdc-drawer-app-content {
  flex: auto;
  overflow: auto;
  position: relative;
}

.main-content {
  overflow: auto;
  height: 100%;
}

.app-bar {
  position: absolute;
}

// only apply this style if below top app bar
.mdc-top-app-bar {
  z-index: 7;
}

使这项工作的更改：

  • 首先，您不需要课程mdc-top-app-bar--fixed-adjust，因为我们不再需要调整项目
  • 接下来，将标头本身移动到app content（此处称为mdc-drawer-app-content）中。

我查看了这个示例的 HTML以了解他们自己是如何做到的
