I am using Blueimp File Upload plugin to upload file. Let say I have following form:

   <input type="text" name="n3" />
   <input type="text" name="n3" />
   <input type="file" name="files" id="file" style="display: none" multiple/>
   <button>Upload</button>
</form>

My job is

I want to upload files+data when use click Upload button. I have done auto file upload i.e. uploading file just after drag drop or selecting file.

But for this one I have no idea how to do.Can I have some simple example for this kind of cases?

You need something like this:

var sendData= true;  
$('#file').fileupload({
   dataType : 'json',
   autoUpload : false,
   add : function(e,data){
      $("#myForm button").on("click",function(){
          if(sendData){
              data.formData = $("#myForm").serializeArray();              
              sendData = false;
          }

          data.submit();
      });
   },
   done: function(e,data){
       sendData = true;
   }
})
