"Springmvc" "Easyui" about using Easyuiform upload file, return jsonie prompt download file solution!

Let's talk about the environment.

Easyui+springmvc+mybatis

Because by normal means, can not use Ajax to submit a form containing files, so think of using Easyui form to submit, Easyui form encapsulated a set of pseudo-Ajax submission method, so can play the role of the Ajax file form!

This sets the corresponding type to JSON, that is, the type of final response is still the JSON type, so

In allowing the corresponding list to add a

Then in the foreground you need to format the returned text as a JSON object in two ways

1,var obj= "(" +data+ ")";

2,var Obj=$.parsejson (data);

And then test the perfect pass, no longer prompted to download the file!
