google places autocomplete suggestion trigger after X characters

I am attempting to limit the display of suggestions for the Google Place Autocomplete API.

Since the Google API charges a API Call per character entered in the field, I would like to restrict the suggestions to only be shown after X amount of characters have been entered.

My initialization of the autocomplete is as standard as it gets.

var input = document.getElementbyId('Searchbox');
var autocomplete = new google.maps.places.autocomplete(input)

Any tips or suggestions would be greatly appreciated



Welcome to StackOverflow, cfair22, here we usually don't do the coding for you, but you can read the length of a string in javascript using length.

var input = document.getElementById("Searchbox");
if(input.length > 3)
    // ...

In this example, you can replace // ... with your code and it will only be fired if the input has length 4 or higher.

Also, I recommend that you cache results for as long as you like, to avoid useless charges.
