在Page.vue中,修改itemW的值,設置每列的最小寬度。例如:itemW="200"(意為200px)。list為數組。高度不用設置,:是我為了創造卡片高度加上去的,不加就顯示卡片的原來大小。
經測試,created加載數據正常,mounted加載、更新數據正常。
Page.vue
<template> <div class="container"> <w-f-column itemW="200"> <template slot-scope="{columnNum,columnIndex}"> <water-follow :list="list" :columnNum="columnNum" :columnIndex="columnIndex"> <template slot-scope="{item,index}"> <div class="my-box" :>{{item}}-{{index}}</div> </template> </water-follow> </template> </w-f-column> </div> </template> <script> import WFColumn from '../waterFollow/WFColumn' import WaterFollow from '../waterFollow/WaterFollow' export default { name: 'page', components: {WaterFollow, WFColumn}, data () { return { list: [] } }, created () { // 有初始數據 for (let i = 0; i < 50; i++) { this.list.push(Math.floor(Math.random() * 301 + 200)) } }, mounted () { // 模擬網絡請求 // window.setTimeout(() => { // this.list = [] // for (let i = 0; i < 50; i++) { // this.list.push(Math.floor(Math.random() * 301 + 200)) // } // }, 1000) // -- 分割 -- // 模擬數據不斷變化 // window.setInterval(() => { // this.list = [] // for (let i = 0; i < 50; i++) { // this.list.push(Math.floor(Math.random() * 301 + 200)) // } // }, 1000) } } </script> <style scoped lang="scss"> .container{ width: 100%; background: gray; .my-box{ width: 200px; background: #000; margin-bottom: 20px; color: #fff; } } </style>
WFColumn.vue
<template> <div class="wf-container"> <div class="wf-column" v-for="(item,index) in columnNum" :key="'column-'+index" :name="index"> <slot :columnNum="columnNum" :columnIndex="index"></slot> </div> </div> </template> <script> export default { name: 'WFColumn', props: ['itemW'], data () { return { columnNum: 0 } }, created () { this.columnNum = Math.floor(document.body.clientWidth / this.itemW) window.onresize = () => { this.columnNum = Math.floor(document.body.clientWidth / this.itemW) } } } </script> <style scoped lang="scss"> .wf-container{ width: 100%; display: flex; .wf-column{ flex: 1; } } </style>
WaterFollow.vue
<template> <div> <div v-for="(item,index) in list" :key="'item-'+index" class="item" :id="'card-'+columnIndex+'-'+index" v-if="load?(record[index].index===columnIndex):true"> <slot :item="item" :index="index"></slot> </div> </div> </template> <script> export default { name: 'WaterFollow', props: ['list', 'columnNum', 'columnIndex'], data () { return { column: 0, record: [], load: false, update: false } }, methods: { calculateColumn () { let cList = [] for (let i = 0; i < this.columnNum; i++) { cList.push(0) } for (let i = 0; i < this.record.length; i++) { let index = 0 for (let j = 0; j < cList.length; j++) { if (cList[index] > cList[j]) { index = j } } cList[index] += this.record[i].height this.record[i].index = index } }, recordInit () { for (let i = 0; i < this.list.length; i++) { this.record.push({index: -1, height: -1}) } }, initHeightData () { for (let i = 0; i < this.list.length; i++) { if (document.getElementById('card-' + this.columnIndex + '-' + i)) { let h = document.getElementById('card-' + this.columnIndex + '-' + i).offsetHeight this.record[i].height = h } } } }, beforeCreate () {}, created () { this.load = false this.recordInit() }, beforeMount () {}, mounted () { this.initHeightData() this.calculateColumn() this.load = true }, beforeUpdate () {}, updated () { if (this.update) { this.initHeightData() this.calculateColumn() this.update = false this.load = true } }, beforeDestroy () {}, destroyed () {}, watch: { columnNum (curr, old) { this.calculateColumn() }, list (curr, old) { console.log('list change') this.recordInit() this.load = false this.update = true } } } </script> <style scoped> </style>
