1,为保证点击加号出来的select标签的v-model不一样,将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body传递
let body={
    formtips:this.formtips,
    cataloglist:this.cataloglist,
    timestart:this.timestart,
    timeend:this.timeend
}

默认高级搜索











作者搜索










点击减号减少搜索条件









增加搜索条件,此时三列搜索条件,选择搜索内容
















点击检索,打开控制台查看body内容
