1.新建common/comp文件夹，将colorText.css,colorText.hml和colorText.js三个文件拷贝进去
  
  2.index.hml中引入组件<color-text></color-text>，从index.js中传入content
  <element name="color-text" src="../../common/comp/colorText.hml"></element>
  <div class="container">
      <color-text content="{{ content }}"></color-text>
  </div>

  3.index.js中传入需要设置的段落，通过this.$child("colorText").findAndSetStrColor()来给指定文字设置指定颜色
  export default {
       data: {
              /*展示文本*/
              content: `You can get 500 credits after connect and share the WIFI`,
          },
       onShow(){
           /*调用子组件设置颜色方法*/
           this.$child("colorText").findAndSetStrColor('You','#ff8000')
           this.$child("colorText").findAndSetStrColor('can','#008888')
           this.$child("colorText").findAndSetStrColor('500','#98FB98')
           this.$child("colorText").findAndSetStrColor('WIFI','#FF0000')
       }
  }
