本文为大家分享了vue2.0多条件搜索组件的实现方法，供大家参考，具体内容如下

搜索条件为死数据，通过select下拉，选取多个条件；同时可点击加号增加搜索条件，点击减号减少搜索条件；

代码如下：

<template> 
 <div class="retrievalmian"> 
 <div class="retrievaltitle">

1、为保证点击加号出来的select标签的v-model不一样，讲v-model与v-for的item绑定；<divclass="formtips"v-for="(item,index) in formtips"><selectclass="formcontrol"v-model="item.titletype" >

2、当点击减号使搜索条件只剩下一列时，减号消失<spanclass="tipsicon removeminus" @click="removeminus"v-show="formtips.length>=4" ></span>；同理给加号增加条件，通过长度判断，限制增加的检索条件最多为6列，加号消失

3、点击检索后，使选中的检索条件通过

代码如下：

let body={
 formtips:this.formtips,
 cataloglist:this.cataloglist,
 timestart:this.timestart,
 timeend:this.timeend
}

body传递默认
