Java项目用easyui做树形列表后台代码怎么来准备数据啊？不要概括型答案，要详细过程的，谢谢！
教你怎么解决,下次就知道了.
访问这个地址,是easyui的官网范例,可以看到范例的html里面有这个配置treegrid_data3.json
所以官方的代码用的是这个地址返回的json:.
访问上面的地址,返回值就是你要的:
{"total":9,"rows":[
{"id":1,"region":"Wyoming"},
{"id":11,"region":"Albin","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":1},
{"id":12,"region":"Canon","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":1},

用easyui做的Java项目，新增二维码图片上传，然后存入项目指定的目录下。点击详情时怎样显示二维码图片？
看这里
我就用了这种方法，只要从数据库读取图片的路径就可以了
使用easyui做前台的 Java项目,在本地各浏览器上运行良好,但是部署到服务器上后,格式改变~
这不是兼容问题，你都说了，本地的各个浏览器运行正常。
看看对方检测的是用什么浏览器
java 使用easyui 的弹出层
easyui好久不用了，因为体验问题，已经基本上被淘汰了，你要想好好学，还是看下官网吧
