基于webuploader的大文件上传实例

说明

因为原始webuploader.js不支持为formData设置函数类型参数，这将导致不能在控件初始化后修改该参数，所以修改了对应源码，大概在webuploader.js源码的3170行。

具体细节请参看这里。

感谢分享 不过我用demo上传文件时 最后文件大小是0kb的tem文件

java 火狐12 内存暴涨

使用火狐浏览器测试的时候发现，flash加载文件，内存暴涨，上传1GB左右文件就内存不足了，（本机8GB），感觉没有释放资源呀。。。。求解

chunk的验证

请问，在chunk的验证部分，ajax那部分代码是怎么实现的啊？

beforeSend: function(block){ //分片验证是否已传过，用于断点续传 var task = new $.Deferred(); $.ajax({ type: "POST" , url: backEndUrl , data: { status: "chunkCheck" , name: uniqueFileName , chunkIndex: block.chunk , size: block.end - block.start } , cache: false , timeout: 1000 //todo 超时的话，只能认为该分片未上传过 , dataType: "json" }).then(function(data, textStatus, jqXHR){ if(data.ifExist){ //若存在，返回失败给WebUploader，表明该分块不需要上传 task.reject(); }else{ task.resolve(); } }, function(jqXHR, textStatus, errorThrown){ //任何形式的验证失败，都触发重新上传 task.resolve(); }); return $.when(task); }

WebUploader 有实现得不好的地方，欢迎提 pr 啊。

希望解决这个错误

进度条问题

暂停后继续的文件进度条从0开始，怎样改成从暂停时的进度开始？

汇报一个bug

分片附件与非分片附件同时上传时，首个分片会失败，错误调用为另一个文件的md5

“暂停”问题

多文件上传时，“暂停”某个文件上传，当其他文件全部上传完毕后，将刚刚暂停的文件继续上传，结果无法继续上传，直接停住了

如何上传文件夹？

怎样可以上传整个文件夹？实现了吗？

前台页面有木有

多线程上传文件损坏

多文件上传以后，文件打不开，提示已经损坏，在后台合并时候已经加过锁，java代码。老板碰到过这个问题吗？

上传100%以后分片不能合并？

分片上传用demo里面的php方式接受，reponse一直卡在{"status":0的状态 然后文件夹里也有.tmp文件的？
