javascript - VueJS 砖石布局

现在我尝试将其实现为 vue 组件，以便可以在任何 View 页面上渲染。

你可以通过npm安装它

npm install masonry-layout --save

然后将其导入到您的组件中(如果您愿意，也可以导入到全局组件中)

组件

import Masonry from "masonry-layout";

export default {

    mounted: function () {

        // initialization of masonry

        var grid = document.querySelector('.masonry-grid');
        var msnry = new Masonry( grid, {
            // options...
            columnWidth: '.masonry-grid-sizer',
            itemSelector: '.masonry-grid-item',
            percentPosition: true
        });
    }
}
