本文实例为大家分享了vue插件tab选项卡的使用方法,供大家参考,具体内容如下

基本用法

<template>
 <tab :options="tabOpt" :state.sync="stateIndex"></tab>
</template>
<script type="text/babel">
 import tab from 'components/tab_touch';
 export default {
 data(){
 tabOpt:undefined,
 stateIndex:0
 },
 components:{
 "tab":tab
 },
 ready(){
 this.tabOpt={
 count: 2.3,
 pin:true,
 htmls:[
  "<span>白日登山</span>",
  "<span>望烽火</span>",
  "<span>黄昏饮马</span>",
  "<span>傍交河</span>",
  "<span>行人刁斗</span>",
  "<span>风沙暗</span>",
  "<span>公主琵琶</span>",
  "<span>幽怨多</span>",
  "<span>野营万里</span>",
  "<span>无城郭</span>",
  "<span>雨雪纷纷</span>",
  "<span>连大漠</span>"
 ],
 slideCallback:function (dex) {
 console.log(dex);
 },
 tabClassName:"tab",
 tabActiveClassName: "active"
 }
 }
 }
</script>
