Chrome extension looping through javascript object not working -

i building chrome extension , running following script:

var group = {         'object1': {             option1: '',             option2: ''         },         'object2': {             option1: '',             option2: ''         }     };  chrome.tabs.executescript({     code: " \         var group_array = [" + object.keys(group) + "]; \         console.log(group_array[0]); \     " }); 

for reason, console.log returns object1 not defined. wanted console.log return name of first object in group, should return object1.

what doing wrong?

i test it. problem is:

"["+['object1','object2']+"]" -> "[object1,object2]" 

so

var group_array = [object1, object2]; 

and if eval string directly, object1 , object2 treated variable instead of string, , since there not variable named object1 , object2, evaluation failed.

to achieve want, can loop array of object.keys(group), , append keys code 1 one, or can directly using json.stringify parse result string array:

" \     var group_array = " + json.stringify(object.keys(group)) + "; \     console.log(group_array[0]); \ "
