需求
1.实现 div 分成各等分(默认最多24分)
2.gutter 缝隙
3.响应各媒体分辨率
知识点
- vue组件三板斧:
<template> <script> <style> props-
v-bind,缩写为: -
props中的类型检测器,validator() -
ES6 ,模板字符串插入表达式,
:class="{[`icon-${iconPosition}`]:true}"
computedmounted- ES,array.push
- ES6 ,扩展运算符
- ES6 ,解构赋值
-
css,媒体响应,
@media -
css,
(display: flex;) (flex-wrap: wrap;) (justify-content: flex-start/center/flex-end) -
scss,for语法,
@for $n from 1 through 24 {} -
scss,插值语法,
&.#{$class-prefix}#{$n} {}
关键点
- 使用
v-bind和computed动态绑定 prop 值 - 了解生命周期
- created 是生成一个不加载页面中的对象,mounted 是将对象挂到页面中
- 使用 mounted 和 this 将 props 数据传递给子组件
- 使用 scss 插值语法将各 class 对应各自媒体响应的样式
