Today, Xiaobian will share with you the relevant knowledge points on how to realize avatar processing in Vue. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you will gain something after reading this article. Let's find out together.

code implementation

//outside to give a div and limit the width and height, text-align center, overflow hidden //userInfoList.avatar is the avatar URL returned to me by the background

import { head, heads } from '@/assets/js/base' // 存放head，heads目录引入export default {data(){ return { listQuery:{ pg: 1, ps: 10 }},methods:{ //获取用户详情 getUserInfoList(){ getlist('mobile/user/pers/detail', funciton(res) { if(data.code == ERR_OK){ _this.userInfoList = res.data // 单个头像处理，$nextTick处理去报 数据加载完成后 在进行图 _this.$nextTick(function () { head(res.data.avatar, 'userhead') }) // 下拉加载多个头像处理 res.data.item.forEach((item, index) => { if(_this.listQuery.pg>1){ // 下拉加载时，头像依然要进行处理 let count = (10*(_this.listQuery.pg -1) + index) _this.$nextTick(function () { heads(item.adatar, count, 'headitem') }) }else{ _this.$nextTick(function () { heads(item.adatar, index, 'headitem') }) } } _this.listQuery.pg++ } }) }

assets文件js下的base.js

// 单个头像处理export function head (objUrl, id) { let _userhead = document.getElementById(id) if(_userhead){ if(objUrl){ let img = new Image() img.src = objUrl img.onload = function () { let _width = img.width let _height = img.height if(_width >= _height){ _userhead.style.width = '100%' }else{ _userhead.style.height = '100%' } } }else{ _userhead.style.width = '100%' } }}// 多个头像处理export function heads (objUrl, index, className) { let _heads = document.getElementsByClassName(className)[index] if(_heads){ if(objUrl){ let img = new Image() img.src = objUrl img.onload = function () { let _width = img.width let _height = img.height if(_width >= _height){ _heads.style.width = '100%' }else{ _heads.style.height = '100%' } } }else{ _heads.style.width = '100%' } }}以上就是"Vue中如何实现头像处理"这篇文章的所有内容，感谢各位的阅读!相信大家阅读完这篇文章都有很大的收获，小编每天都会为大家更新不同的知识，如果还想学习更多的知识，请关注行业资讯频道。
