Extjs 我无法执行success函数

Question

后台代码
  return this.JsonFormat(new ExtResult { success = true}); 
Extjs代码  
if (form.form.isValid()) {
                        form.getForm().submit({
                            url: '/StudentInformations/StudentBulkImport',
                            params: { 'trainingBatch': trainingBatch },
                            waitTitle: '提示',
                            waitMsg: '请等待...',
                            success: function () {
                                alert(success);
                                Ext.Msg.alert('提示', '导入成功！');
                                win.close();
                            },
                            failure: function (form, action) {
                                Ext.Msg.alert('提示', "导入失败");
                                win.close();
                            }
                        })
                    }为什么无法进入success函数里

Answer 1

检查下 form.form.isValid()是否为true
在submit之前alert一下.
