JavaScript compare arrays

Question

I have an array in the following format:

var markers = [
    [\'Title\', 15.102253, 38.0505243, \'Description\', 1], 
    [\'Another Title\', 15.102253, 38.05052         


        

Answer 1

Couldn't you just use a nested loop here?

var filteredMarkers = [];

for(var i = 0; i < markers.length; i++) {

    for(var j = 0; j < queryStringArray.length; j++) {

        // this might need to be changed as your markers has index 4 as a number whereas the queryString array appears to be strings.
        if(markers[i][4] === queryStringArray[j]) {

            filteredMarkers.push(markers[i]);
            break;

        }

    }

}
