i'm using google maps distance matrix api search distances between 1 city , lot of other cities, returns array looks following:
var array = [{ "distance": { "text": "1,031 km", "value": 1030580 }, "duration": { "text": "9 hours 47 mins", "value": 35216 }, "status": "ok", "location": "akron oh " }, { "distance": { "text":

"zero_results", "location": "hybrid " }, { "status": "zero_results", "location": "hyderabad india " }] i need iterate on array , return array containing ten of these results have lowest number of distance. you'll notice of results "status":"zero_results", need avoid those.
so far, thinking along these lines:
var arrayoften = []; $.each(array,function(index,location){ })
on way to
- filter out unwanted entries
- sort array distance
- get first 10 elements
var result = array .filter(function(city) { return city.status === "ok"; }) .sort(function(a, b) { return a.distance.value - b.distance.value; }) .slice(0, 10); or arrow functions (thank es2015):
var result = array .filter(city => city.status === 'ok') .sort((a, b) => a.distance.value - b.distance.value) .slice(0, 10);
