实现搜索代码:
methods:{
search() {
if (this.keyword == '') { //如果没有输入内容,不让往下执行
return
}
this.resultList = [] //每次搜索对结果数组做初始化
this.deviceList.forEach((item) => { //把初始数据进行遍历
/**
下面是把初始数据中的每一条数据的四个字段分别去和输入的内容进行匹配,
如果某一字段中包含输入的内容,就往resultList中加
**/
if (item.name.indexOf(this.keyword) > -1 ||
item.date.indexOf(this.keyword) > -1 ||
item.adress.indexOf(this.keyword) > -1 ||
item.type.indexOf(this.keyword) > -1) {
this.resultList.push(item)
}
})
if (this.resultList.length == 0) { //如果没有匹配结果,就显示提示信息
this.isShowTip = true
}
}
}
实现高亮显示:主要技术点(map映射)
this.resultList.map((item) => {
item.name = this.brightKeyword(item.name)
item.date = this.brightKeyword(item.date)
item.adress = this.brightKeyword(item.adress)
item.type = this.brightKeyword(item.type)
})
})
},
brightKeyword (val) {
let keyword = this.keyword
if (val.indexOf(keyword) !== -1) {
return val.replace(keyword, `<font color='#42cccc'>${keyword}</font>`)
} else {
return val
}
}
}
完整代码:
<template>
<div class="bright-index">
<div class="search-box">
<input type="text" v-model="keyword" class="input" placeholder="请输入搜索内容, 提示:搜索设备">
<button class="btn" @click="search">搜索</button>
