前言

在前端开发中，界面的设计和交互是至关重要的一部分。一个直观、易用的界面往往离不开各种组件的运用。本文将聚焦于Element-ui中的两个常用组件——Icon图标和Button按钮，分别介绍它们的基本用法和一些实用技巧。Icon图标为界面添加了更多的元素，而Button按钮则是用户与页面进行交互的重要媒介，通过深入理解它们，我们可以更好地打造出美观、实用的前端界面。

一、Icon 图标

1.1 作用

提供了一套常用的图标集合。

1.2 使用方法

直接通过设置类名为 el-icon-iconName 来使用即可。例如：

<i class="el-icon-edit"></i>
<i class="el-icon-share"></i>
<i class="el-icon-delete"></i>
<el-button type="primary" icon="el-icon-search">搜索</el-button>

我们只需要使用i标签class为图标名称即可.如果你使用的是i标签
如果是其他，则使用icon属性

<el-button type="primary" icon="el-icon-edit"></el-button>
<el-button type="primary" icon="el-icon-share"></el-button>
<el-button type="primary" icon="el-icon-delete"></el-button>

<el-button type="primary">上传<i class="el-icon-upload el-icon--right"></i></el-button>

2.5 按钮组

以按钮组的方式出现，常用于多项类似操作。

使用<el-button-group>标签来嵌套你的按钮。

<el-button-group>
  <el-button type="primary" icon="el-icon-arrow-left">上一页</el-button>
  <el-button type="primary">下一页<i class="el-icon-arrow-right el-icon--right"></i></el-button>
</el-button-group>
<el-button-group>

  <el-button type="primary" icon="el-icon-share"></el-button>
  <el-button type="primary" icon="el-icon-delete"></el-button>
</el-button-group>

2.6 加载中

点击按钮后进行数据加载操作，在按钮上显示加载状态。

要设置为 loading 状态，只要设置loading属性为true即可。

<el-button type="primary" :loading="true">加载中</el-button>

2.7 不同尺寸

Button 组件提供除了默认值以外的三种尺寸，可以在不同场景下选择合适的按钮尺寸。
额外的尺寸：medium、small、mini，通过设置size属性来配置它们。

<el-row>
  <el-button>默认按钮</el-button>
  <el-button size="medium">中等按钮</el-button>
  <el-button size="small">小型按钮</el-button>
  <el-button size="mini">超小按钮</el-button>
