layui扩展上传组件模拟进度条的方法

如下所示：<divid="uploadPatchForm"style="display:none"class="roundRect"><divid="uploadLoadingDiv"><d

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：
