实现需求
通过搜索，将搜索结果关联到当前页面的对象，原来点击一下就关联，弹框关闭
现在需要支持同一个搜索结果多次点击关联，加快处理速度
实现效果
实现思路
将捕获点击事件，并且阻止传播 @click.stop="handleItemClick(item)"，@select就不能收到点击事件，就不会关闭搜索结果了
还需要设置样式，将li 标签的padding值去掉，以免点击触发到结果项外边，保证结果项将整行都覆盖住
.mo-autocomplete { li { padding: 0; } }
完整代码
<template> <el-autocomplete popper-class="mo-autocomplete" v-model="keyword" style="width: 300px;" :fetch-suggestions="querySearch" :debounce="800" placeholder="搜索" > <template slot-scope="{ item }"> <div class="mo-autocomplete__item" @click.stop="handleItemClick(item)" > <div class="name">{{item.value}}</div> <span class="addr">{{ item.address }}</span> </div> </div> </template> </el-autocomplete> </template> <script> import apiData from './data.json' export default { name: '', data() { return { page: 1, size: 20, keyword: '' } }, methods: { // 点击 handleItemClick(item) { this.handleSelect(item) }, // @select 触发 handleSelect(item) { console.log('handleSelect'); }, // 分页搜索 async search(keywords) { console.log('page', this.page); let start = (this.page - 1) * this.size let end = start + this.size return apiData.slice(start, end) }, // 焦点触发搜索第一页 async querySearch(queryString, cb) { this.page = 1 let list = await this.search(queryString) // 调用 callback 返回建议列表的数据 cb(list) }, }, created() {}, } </script> <style lang="less"> .mo-autocomplete { li { padding: 0; } .mo-autocomplete__item { line-height: normal; padding: 7px; .name { text-overflow: ellipsis; overflow: hidden; } .addr { font-size: 12px; color: #b4b4b4; } .highlighted .addr { color: #ddd; } } } </style>
