Prompt.vue组件

说明：

通过props定制定制的Prompt，可选值
  mode     默认值：prompt， 其他模式：confirm、message(简单的提示，可设置提示显示时间，类似alert，有顶部进度时间条)
  title    默认值：{name:'系统提示',bgColor:'white',color:'black'}
  close    默认值：{bgColor:'white',hoverBgColor:'red',color:'black',hoverColor:'white'}
  bottom   默认值：{bgColor:'white',color:'black'}
  content  其他模式下必选，prompt模式下的默认值：{keyWord:'确认密码',bgColor:'white',color:'black'}
                       其他模式下的默认值：{keyWord:'展示一个弹窗',bgColor:'white',color:'black'}
  buttons  message模式下传入该值无效
           其他模式下的默认值：[{name:'确定',callback:this.sure},{name:'取消',callback:this.cancel}]
  getShow  必须传否则父组件无法控制子组件的展示

使用示例：

    <Prompt Mode="prompt"
            :Buttons="[{name:'确认',callback:sure},{name:'取消',callback:cancel}]"
            :GetShow="setShow"
    ></Prompt>
  </div>
</template>

<script>
//引入
import Prompt from './components/Prompt'
export default {
  name: 'App',
  components: {//注册
    Prompt
  },
  methods:{
    sure(result){//接收prompt模式和confirm模式下的确认的返回值  分别是输入框的值 和 true
      console.log(result);
    },
    cancel(result){//接收prompt和confirm模式下的取消的返回值   分别是null 和 false
      console.log(result);
    },
    setShow(show){
      //通过show传参控制Prompt组件是否显示
      //必选参数是是否显示Boolean  可选参数是显示时间（在message模式下有效）
      this.setShow = show;
    }
  }
}
