按钮组件的详细使用

日后使用element ui的相关组件时需要注意的是 所有组件都是el-组件名称开头
创建按钮：<el-button>默认按钮</el-button>

组件属性使用

总结：在element中所有的组件的属性使用都是直接将属性名=属性值方式写在对应的组件标签上，boolean类型的属性默认为false可以简写一个属性名字表示为true。

示例

    <div>
      <h1>创建简单的按钮</h1>

      <el-button type="primary" size="mini" round="true"  loading>primary</el-button>
      <el-button type="primary" size="small" round="true" disabled>primary</el-button>
      <el-button type="primary" size="medium" circle icon="el-icon-delete-solid"></el-button>
