移动端图片压缩上传功能如何实现?
做移动端开发的时候,form里面的file后台经常获取不到,用foemdata也拿不到
找到了一个formdata的脚本
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" name="viewport"> <title>移动端图片压缩上传demo</title> <style> *{margin: 0;padding: 0;} li{list-style-type: none;} a,input{outline: none;-webkit-tap-highlight-color:rgba(0,0,0,0);} #choose{display: none;} canvas{width: 100%;border: 1px solid #000000;} #upload{display: block;margin: 10px;height: 60px;text-align: center;line-height: 60px;border: 1px solid;border-radius: 5px;cursor: pointer;} .touch{background-color: #ddd;} .img-list{margin: 10px 5px;} .img-list li{position: relative;display: inline-block;width: 100px;height: 100px;margin: 5px 5px 20px 5px;border: 1px solid rgb(100,149,198);background: #fff no-repeat center;background-size: cover;} .progress{position: absolute;width: 100%;height: 20px;line-height: 20px;bottom: 0;left: 0;background-color:rgba(100,149,198,.5);} .progress span{display: block;width: 0;height: 100%;background-color:rgb(100,149,198);text-align: center;color: #FFF;font-size: 13px;} .size{position: absolute;width: 100%;height: 15px;line-height: 15px;bottom: -18px;text-align: center;font-size: 13px;color: #666;} .tips{display: block;text-align:center;font-size: 13px;margin: 10px;color: #999;} .pic-list{margin: 10px;line-height: 18px;font-size: 13px;} .pic-list a{display: block;margin: 10px 0;} .pic-list a img{vertical-align: middle;max-width: 30px;max-height: 30px;margin: -4px 0 0 10px;} </style> </head> <body> <input type="file" id="choose" accept="image/*" multiple> <ul class="img-list"></ul> <a id="upload">上传图片</a> <span class="tips">只允许上传jpg、png及gif</span> <div class="pic-list"> 你上传的图片(图片有效期为1分钟): </div> <script src="/UploadFiles/2021-04-02/jquery-2.1.1.min.js">以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
