使用 CDN 的 Web 模式抽屉示例的材料组件



关于将Material Components用于Web CDN进行前端设计的示例并没有那么有用。

我找到了这个模态抽屉的演示,但它似乎没有使用已发布的 CSS 和 JavaScript CDN。演示:模态抽屉演示

如何使用材料组件的 CDN 实现模态抽屉?

使用 unpkg 捆绑包而不是通过 webpack 使用单个组件有点困难。入门文档有所帮助,但仍然很难翻译文档以用于各种组件。最棘手的部分是弄清楚如何实例化各种组件(因为没有一种适合所有方法的方法(。下面是一个使用 unpkg 的模态抽屉组件的快速示例,可帮助您开始操作。

const drawer = mdc.drawer.MDCDrawer.attachTo(document.querySelector('.mdc-drawer'));
const topAppBar = mdc.topAppBar.MDCTopAppBar.attachTo(document.querySelector('.mdc-top-app-bar'));
topAppBar.listen('MDCTopAppBar:nav', () => {
drawer.open = !drawer.open;
});

由于代码库的更改,当前选择的答案在版本 v10 或更高版本上不起作用。事实上,目前没有MDCList的"工作"实现,这是抽屉用来显示列表的,目前你可以使用mdc-evolution-list(这似乎不适用于CDN(,或者回到旧的mdc-evolution-deprecated。因此,上面的代码片段实际上应该是:

const drawer = mdc.drawer.MDCDrawer.attachTo(document.querySelector('.mdc-drawer'));
const topAppBar = mdc.topAppBar.MDCTopAppBar.attachTo(document.querySelector('.mdc-top-app-bar'));
topAppBar.listen('MDCTopAppBar:nav', () => {
drawer.open = !drawer.open;
});

如果您正在使用 webpack 或自己编译 SCSS,则可以使用以下方法导入新列表:

@use "@material/list/evolution-mixins"as list-evolution-mixins;
@include list-evolution-mixins.core-styles();
