如下所示：

<div id="uploadPatchForm" style="display:none" class="roundRect"> <div id="uploadLoadingDiv"> <div class="layui-progress" lay-showpercent="true" lay-filter="demo" > <div class="layui-progress-bar layui-bg-red" lay-percent="0%"></div> </div> </div> <form class="layui-form" enctype="multipart/form-data"> <div class="layui-form-item layui-upload"> <span id="uploadName" style="line-height: 3;"></span> <button type="button" class="layui-btn layui-btn-normal" id="test8" style="float: right;"> <i class="layui-icon"></i> </button> </div> <div class="layui-form-item"> <div class="layui-input-block"> <input type="radio" name="upgradeType" value="30011001" title="手动升级"> <input type="radio" name="upgradeType" value="30011002" title="自动升级" checked> </div> </div> <div class="layui-form-item"> <div class="layui-input-block"> <a class="roundCornerDiv aLineGray" href="javascript:layer.closeAll();" rel="external nofollow" > <span type="reset" class="ButtonText popupCloseBtn">取消</span> </a> <a class="roundCornerDiv aLineOrange"> <button class="ButtonText submitBtn" type="button" id="test9">立即提交</button> </a> </div> </div> </form></div>layui.use(['upload','element','layer'], function(){ var upload = layui.upload,element = layui.element,layer = layui.layer; var timer;//定义一个计时器 //选完文件后不自动上传 upload.render({ elem: '#test8' ,url: 'upload' ,async: false ,method: 'post' ,data: { upgradeType: function(){ return $("input[name='upgradeType']:checked").val();//额外传递的参数 } } ,auto: false ,accept: 'file' //普通文件 ,exts: 'zip' //只允许上传压缩文件 ,field:'uploadFile' ,bindAction: '#test9' ,choose: function(obj){//这里的作用是截取上传文件名称并显示 var uploadFileInput=$(".layui-upload-file").val(); var uploadFileName=uploadFileInput.split("\\"); $("#uploadName").text(uploadFileName[uploadFileName.length-1]); } ,before: function(obj){ //obj参数包含的信息，跟choose回调完全一致 layer.load(); //上传loading var n = 0; timer = setInterval(function(){//按照时间随机生成一个小于95的进度，具体数值可以自己调整 n = n + Math.random()*10|0; if(n>95){ n = 95; clearInterval(timer); } element.progress('demo', n+'%'); }, 50+Math.random()*100); } ,done: function(res){ clearInterval(timer); element.progress('demo', '100%');//一成功就把进度条置为100% layer.closeAll(); layer.msg('上传成功');} ,error: function(index, upload){element.progress('demo', '0%');layer.closeAll(); //关闭所有层layer.msg('上传更新包失败'); }});});

哎，好难调格式！

效果如下，截图工具反应迟钝看起来有点失真，实际测试是ok的：
