Creating markers within a loop

Question

Using OpenLayers, I want to display multiple markers over an OSM map by creating them from an array within a while loop.

The code works when I hard-code a single coordinate, but not when reading the coordinates from the array.

What can be done to construct the markers?

You can test it via:

ol.proj.fromLonLat([lonlatarray[i]]) 
//  ol.proj.fromLonLat([16.332253, 48.503684])

Answer 1

You can declare your coordinates as 2D array of numeric values.:

var lonlatarray = [
[16.332253, 48.503684],
[16.432503, 48.565917],
[16.402290, 48.473580]
];

You can then call each coordinates in the loop using

ol.proj.fromLonLat(lonlatarray[i])
