Zugriff auf variable einer anderen renderer function

Shopware 5 Programmierung

Ich versuche im unteren abgekürzten Code-Beispiel in var ArticleName Zugriff zu erhalten auf die Variable md_variation, die zuvor gesetzt wurde.

Wie komme ich da dran ?

 

Ext.override(Shopware.apps.Order.view.detail.Position, {

    getColumns: function() {
        var me = this;
        var columns = me.callOverridden(arguments);
        var md_upload = {};
        var response = {};

        var ID = null;
        var MDUPload= {
            header: 'xy',
            dataIndex:'xy',
            flex: 3,
            renderer: function(value, metadata, record, rowIndex, colIndex, store, view){
                var dataRow ='';
                var md_variation = {};
                Ext.Ajax.request({
                    url: '{url controller=AttributeData action=loadData}',
                    params: {
                        _foreignKey: record.get('id'),
                        _table: 's_order_details_attributes',
                     },
                    async:false,
                    success: function(responseData) {

                        ID = Ext.JSON.decode(response.data['__attribute_detailID']);
                        if ( !isNaN( parseFloat(ID)))
                        {
                            md_variation[ID] = Ext.JSON.decode(response.data['__attribute_md_variation']);
                        }
                    }
                });

                return dataRow;
            }
        };

        var ArticleName = {
            header: 'Artikel',
            dataIndex: 'articleName',
            flex: 2,
            renderer: function(val, metadata, record) {
                var variationRow='';
                     if ( !isNaN( parseFloat(record['raw']['id'])))
                {
                    for(var i=0; i < md_variation[record['raw']['id']].length;i++)
                    {
                        variationRow +=md_variation[record['raw']['id']][i]['name']+':'+md_variation[record['raw']['id']][i]['value']+'';
                    }
                }
                return variationRow;
            }
        };
        columns = Ext.Array.insert(columns, 8, [MDUPload]);
        columns = Ext.Array.remove(columns,1);
        columns = Ext.Array.insert(columns,1, [ArticleName]);


        return columns;
    }
});
