The getStoresJS method creates a JavaScript array with all information entitled to the user according to the access control policy. The information includes the stores that the user is entitled to access, the fulfillment centers of those stores, and the languages, which each store supports. The following is an example of a JavaScript array created by a call to the getStoresJS method:

stores[0] = new Object();
stores[0].storeId = '10001'
stores[0].languages = new Array();
stores[0].languages[0] = new Object();
stores[0].languages[0].langId = '-1';
stores[0].languages[0].langDesc = 'United States English';
stores[0].languages[1] = new Object();
stores[0].languages[1].langId = '-3';
stores[0].languages[1].langDesc = 'German';
stores[0].languages[2] = new Object();
stores[0].languages[2].langId = '-5';
stores[0].languages[2].langDesc = 'Spanish';
stores[0].languages[3] = new Object();
stores[0].languages[3].langId = '-2';
stores[0].languages[3].langDesc = 'French';
stores[0].languages[4] = new Object();
stores[0].languages[4].langId = '-4';
stores[0].languages[4].langDesc = 'Italian';
stores[0].languages[5] = new Object();
stores[0].languages[5].langId = '-10';
stores[0].languages[5].langDesc = 'Japanese';
stores[0].languages[6] = new Object();
stores[0].languages[6].langId = '-9';
stores[0].languages[6].langDesc = 'Korean';
stores[0].languages[7] = new Object();
stores[0].languages[7].langId = '-6';
stores[0].languages[7].langDesc = 'Brazilian Portuguese';
stores[0].languages[8] = new Object();
stores[0].languages[8].langId = '-7';
stores[0].languages[8].langDesc = 'Simplified Chinese';
stores[0].languages[9] = new Object();
stores[0].languages[9].langId = '-8';
stores[0].languages[9].langDesc = 'Traditional Chinese';
