javascript - Updating MongoDB array from variable array in batch operation? -

-
i working in node.js , attempting push or pull contents of array mongodb collection. [working] code pull objects array in fieldarray looks this: for (var i=0; < mylist.length; i++) { collection.update( {field:"myvalue"}, {$pull: {fieldarray: mylist[i]}}, function(err, item){...} ); } i'm aware of ability use $push/$each, $addtoset/$each , $pullall don't seem accept values dynamically array (or haven't found indication can). basically, i'd able use function array of 1 item or 1 hundred, using appropriate batch calls. is there way make such call without having loop through separate call on database each iteration? you want $pullall . trying iterate over collection.update( { "field": "myvalue" }, { "$pullall": { "fieldarray": mylist } } ) if doesn't work then array elements not matching structure used in document. make them way.
