本文實例為大傢分享瞭基於Vue可左右滑動按鈕組組件,供大傢參考,具體內容如下
左右兩箭頭控制按鈕組左右移動,雙擊到最左或最右邊,功能比較簡單。如下所示
<template> <div class="demoButtons"> <div class="buttonF"> <el-row style="height:30px "> <el-col class="lableI"><i class="el-icon-arrow-left " @click="moveButtons('left')" @dblclick="moveSide('left')" /></el-col> <el-col ref="buttonBody" class="buttonBody"> <el-row id="buttonRow" ref="buttonRow"> <el-tag :style="{'width':buttonWidth+'px'}" v-for="(item, index) in buttonData" :key="index" :type="index == clickIndex ? '' : 'info'" @click="resetData(index, item)"> <el-tooltip v-if="item.name && item.name.length > parseInt(buttonWidth/12) - 1" placement="top" :content="item.name" effect="light"> <span>{{ resetName(item.name) }}</span> </el-tooltip> <span v-else>{{ item.name }}</span> </el-tag> </el-row> </el-col> <el-col class="lableI"><i class="el-icon-arrow-right " @click="moveButtons('right')" @dblclick="moveSide('right')" /></el-col> </el-row> </div> </div> </template> <script> import $ from 'jquery' export default { props: { buttonData: { type: Array, default: () => { return [] } }, buttonWidth: { type: Number, default: 62 } }, data () { return { clickIndex: 0, currentSite: 0, showCount: 0, clickTimer: null, } }, watch: {}, created () { // this.setButtons() }, mounted () { this.$nextTick(() => { this.showCount = parseInt(this.$refs.buttonBody.$el.clientWidth / this.buttonWidth) // 一行能展示幾個按鈕 }) }, methods: { //設置名字 resetName (val) { let i = parseInt(this.buttonWidth / 12) - 1; if (val && val.length > i) { return val.slice(0, i) } else { return val } }, // 單擊移一格 moveButtons (val) { if (this.clickTimer) { window.clearTimeout(this.clickTimer) this.clickTimer = null } this.clickTimer = window.setTimeout(() => { this.$nextTick(() => { if (val == 'left') { if (this.currentSite < 0) { this.currentSite = this.currentSite + this.buttonWidth } } else { const totalCount = this.buttonData.length // 總共幾個按鈕 const showIndex = -parseInt(this.currentSite / this.buttonWidth) // 向左移瞭幾個按鈕 console.log(totalCount, 'totalLength', this.showCount, showIndex) if (showIndex + this.showCount < totalCount) { this.currentSite = this.currentSite - this.buttonWidth } } $('#buttonRow').animate({ marginLeft: this.currentSite + 'px' }) }) }, 300) }, // 雙擊到邊 moveSide (val) { if (this.clickTimer) { window.clearTimeout(this.clickTimer) this.clickTimer = null } this.$nextTick(() => { if (val == 'left') { this.currentSite = 0 } else { const totalCount = this.buttonData.length // 總共幾個按鈕 if (totalCount > this.showCount) { this.currentSite = -((totalCount - this.showCount) * this.buttonWidth) } } $('#buttonRow').animate({ marginLeft: this.currentSite + 'px' }) }) }, setButtons (data) { this.buttonData = data }, resetData (index, data) { this.clickIndex = index this.$emit('resetData', data) } } } </script> <style lang="scss" scoped> .demoButtons { width: 100%; height: 100%; } .buttonF { width: 100%; margin: 0 auto; height: 30px; line-height: 30px; } .lableI { height: 30px; line-height: 30px; width: 20px; cursor: pointer; } .buttonBody { overflow: hidden; height: 30px; line-height: 30px; width: calc(100% - 40px); white-space: nowrap; } .el-tag { text-align: center; padding: 0px 8px !important; height: 28px; line-height: 28px; cursor: pointer; border-radius: 0px !important; overflow: hidden; font-size: 12px; } </style>
