javascript - google chart function reading as string -

i have array looks this:

var arrayaddcolumn = ["'string', 'ano'", "'number', 'ativo'", "{'type': 'string', 'role': 'tooltip'}", "'number', 'extra'", "{'type': 'string', 'role': 'tooltip'}"]; 

i´m looping array way:

for(var x=0; x<arrayaddcolumn.length;x++){     datatable.addcolumn(arrayaddcolumn[x]); } 

the output should this:

datatable.addcolumn('string', 'ano'); datatable.addcolumn('number', 'ativo'); datatable.addcolumn({'type': 'string', 'role': 'tooltip'}); datatable.addcolumn('number', 'extra'); datatable.addcolumn({'type': 'string', 'role': 'tooltip'}); 

but function reading position in array string , need 2 strings separated comma. how can output that?

you may try this:

var arrayaddcolumn = [['string', 'ano'],                           ['number', 'ativo'],                        [{'type': 'string'}, {'role': 'tooltip'}]];  for(var x=0; x<arrayaddcolumn.length;x++){      datatable.addcolumn(arrayaddcolumn[x][0], arrayaddcolumn[x][1]); }
