After creating a multi-dim array like this, how do I sort it?
Assuming 'markers' is already defined:
var location = [];
for (var i = 0; i < markers.length; i++) {
location[i] = {};
location[i]["distance"] = "5";
location[i]["name"] = "foo";
location[i]["detail"] = "something";
}
For the above example, I need to sort it by 'distance'. I've seen other questions on sorting arrays and multi-dim arrays, but none seem to work for this.
location.sort(function(a,b) {
// assuming distance is always a valid integer
return parseInt(a.distance,10) - parseInt(b.distance,10);
});
javascript's array.sort method has an optional parameter, which is a function reference for a custom compare. the return values are >0 meaning b first, 0 meaning a and b are equal, and <0 meaning a first.
parseFloat(a.distance) would be proper in that case.
Have you tried this?
location.sort(function(a,b) {
return a.distance - b.distance;
});
Both sort functions posted so far should work, but your main problem is going to be using location as a variable as it is already system defined.
