/*临时样式*/ ul,li{ list-style: none; margin:0; padding:0; } .retrievalmian{ margin: 20px; width:75%; } /**/ /*.retrievaltitle{*/ /*background: #FCFCFC;*/ /*}*/ .retrievaltitle .tabbtn:first-child{ margin-right: -5px; } .retrievaltitle .tabbtn:hover{ text-decoration: none; } .retrievaltitle .tabbtn{ padding: 2px 8px; background: #FBFBFB; border: 1px solid #DFDFDF; margin-bottom: -1px; } .retrievaltitle .tabbtn.checked{ color: #E50F10; padding-top: 8px; border-bottom: 1px solid #FBFBFB; } .retrievalbar{ border: 1px solid #E5E5E5; background: #FCFCFC; } .formbody{ position: relative; margin: 10px 0px; } .formoperate{ position: absolute; top:10px; right: 20px; } .formoperate .tipsicon{ color: #59A4D2; display: inline-block; line-height: 15px; cursor: pointer; margin-left: 15px; width: 20px; height: 20px; /*临时*/ text-align: center; border: 1px solid #59A4D2; } .formoperate .addplus{ background: url(../static/img/addplusicon.png) no-repeat center; } .formoperate .removeminus{ background: url(../static/img/removeicon.png) no-repeat center; } .formline{ padding: 5px 30px; } .formtips{ display: inline-block; margin-right: 22px; } .formgroup{ display: inline-block; } .formcontrol{ border: 1px solid #999; width: 80px; height: 25px; } .forminp{ border: 1px solid #146AC4; width: 120px; height: 25px; } .formcontrollarg{ width:120px; height: 25px; } .formsearch{ position: absolute; bottom:10px; right: 20px; } .retrievalsearch{ padding: 5px 20px; } .formgroup .catalog{ border: 1px solid #999; width:120px; height: 25px; cursor: pointer; background: url(../static/img/dropdown.png) no-repeat; background-position: 95% 45%; } .cataloghint{ position: relative; } .cataloglist{ position: absolute; top: -1px; left: 0; padding: 0; border: 1px solid #999; background: #fff; z-index: 10; width: 120px; } .cataloglist li{ padding:2px 5px; } .cataloglist li:hover{ background: #1e90ff; } .checkbox { margin:0px; }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
