jquery - With JSON.stringifyf how do I add square brackets? -

i have code produces json string

{"did":50,"pid":"66","cid":"2","qty":1,"skus":{"ssid":"b931627", "type":"fab" ,"qty":1,"style":""}} 

but need format

{"did":50,"pid":"66","cid":"2","qty":1,"skus":[{"ssid":"b931627", "type":"fab" ,"qty":1,"style":""}]} 

here have far:

 var dataattributes = {    did : $(selector).data('did'),    pid : $(selector).data('pid'),    cid : $(selector).data('cid'),    qty : '1',    coveroptionskus : var ssus = {          ssid : $(selector).data('ssid'),          type : '',          qty : 1,          style : ''        }   }; 

added "" double quotes around dataattributes property names , values

 var dataattributes = {    "did" : $(selector).data("did"),    "pid" : $(selector).data("pid"),    "cid" : $(selector).data("cid"),    "qty" : "1",    // removed `var`    // set `skus` property `array`,    // set properties of object    // within `skus` array    "skus" : [{              "ssid" : $(selector).data("ssid"),              "type" : "",              "qty" : 1,              "style" : ""             }]   };   // call `json.stringify()` `dataattributes` parameter    json.stringify(dataattributes);
