我正试图在extjs中上传一个文件(截至目前的任何扩展名).我有一个模特和商店.文件上传发生在一个窗口,我没有在窗口中的表单.我在网上尝试的所有例子都是使用form.submit().我改为使用和Ajax调用如下所示将数据发送到服务器.

Ext.Ajax.request({

            url : 'qaf/saveSetupDetails.action',

            params : {
                'data' : recordsToSend

            failure : function(response){
                //console.log('error connecting controller');
            },
            success : function(response){
                //console.log('successfully submitted');
            }
        });

要在数据中发送的记录如下所示.

var store = Ext.getStore('SomeStore');
        var modifiedRecords = store.getModifiedRecords();
        var recordsToSend = [];
        if(modifiedRecords.length > 0){
            Ext.each(modifiedRecords, function(record){
                recordsToSend.push(record.data);//I'm sure that this is so dump but this is how I do it for other records which are string and not sure how to do it for a file...
            });
        }
        Ext.USE_NATIVE_JSON = true;
        recordsToSend …
