 修改uplaod.js - 打开layui/modules/upload.js
- 搜索ajax
- 找到url:
- 添加以下代码：
,xhr:l.xhr(function(e){//此处为新添加功能 var percent=Math.floor((e.loaded / e.total)*100);//计算百分比 l.progress(percent);//回调将数值返回
5.upload.js 中 p.prototype.config也要改，加一个xhr的定义，否则传文件时如果不设xhr会报错。 accept:"images",exts:"",auto:!0,bindAction:"",url:"" ,field:"file",method:"post",data:{},drag:!0,size:0 ,xhr:function(){}//此处需要添加
