Hello

I like me create a bus routing finder, only City A (origin), City B (origin), search for the same routes in the cities and show the result

For example
City A - linebus 1, linebus 3, linebus 5
City B - linebus 1, linebus 3, linebus 10

Then should be show 1 and 3 can connect this cities

I found this script online, I dont know it is possible use for my problem or adapt

var city_A= ["bus1", "bus3", "bus5"]
var city_B= ["bus1", "bus3", "bus10"]

for(var i = 0; i<arr1.length; i++){
for(var j=0; j<arr2.length; j++){
if(arr1 === arr2[j]){
//do something
}
}

Or is wrong?

Thanks

        var city_A= ["bus1", "bus1", "bus5"];
        var city_B= ["bus1", "bus3", "bus10"];
        var conLines = [], message;

    for(var i = 0; i<city_A.length; i++){
        for(var j=0; j<city_B.length; j++){
            if(city_A[i] === city_B[j]){
                conLines.push(city_A[i]);
            }
        }
    }

    message = (conLines.length > 0) ? "The following bus lines are able to connect routes betweene cities: " :
                                        "There are no alternative bus routes available!!!";
    alert(message + conLines.toString());
