vue头部导航动态点击处理方法

data: {
       nav:['头条1','头条2'],
       ins:0,//记录当前点击的INDEX
      },

 <div v-for="(item,index) in nav" :class="index == ins ? 'swiper-slide swiper_active' : 'swiper-slide' " @click="topClick(index)">{{item}}</div>

topClick:function(i){
        var t=this;
        t.ins=i;
      },

<template>
  <div id="header" :style="{'position' : customFixed ? 'fixed' : 'absolute'}">
   <slot name="left"></slot>
   {{customTitle}}
   <slot name="right"></slot>
  </div>
</template>

<script>
  export default {
   name: "my-header",
   props:{
    customTitle : {
      type : String,
      default : '标题'
     },
    customFixed: {
      type: Boolean,
      default: false
    }
   }
  }
</script>

<style scoped>
#header{
 width: 100%;height: 40px;background: #666;color: white;text-align: center;line-height: 40px;
 position: absolute;left:0;top: 0;z-index: 10;
}
 #header button {height: 100%;padding: 0 50px;}
 #header button:nth-of-type(1){float: left}
 #header button:nth-of-type(2){float: right}
</style>

在用到头部的地方：

<template>
 <div id="app">
  <my-header custom-title="通讯录" custom-fixed>
   <button @click="backBtn" slot="left">返回</button>
   <button @click="homeBtn" slot="right">主页</button>
  </my-header>
 </div>
</template>
