javascript - run after the callback is finished -


i need run function after displaypredictionsuggestions callback retrieves , stores result in global variable place.

as understand callback runs asynchronously. can't sure callback finished when invoke console.log( json.stringfy( place ) );

how make sure program continues after callback finished (without nesting)?

predictionservice = new google.maps.places.autocompleteservice(); predictionservice.getplacepredictions({      input: '1 street, city' },      displaypredictionsuggestions );  displaypredictionsuggestions = function(predictions, status) {          place = predictions[0]['place_id'];     }  console.log( json.stringfy( place ) );

you can avoid nesting callbacks using promises.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
