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>
   {{custom }}
   <slot name=\"right\"></slot>
  </div>
</template>

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

<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- =\"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>
