How to pass multiple destinations to Google matrix api dynamically?

Question

I want to send one origin and multiple destinations to Google datamatrix api dynamically. It works fine if we use pass values directly as:

service.getDistanceMatrix({
            origins: [document.getElementById("origin1").value],
            destinations: ["kopargaon", "manmad"],
            ....

but if we push location in array and then passed to destination then it wont work. Eg

service.getDistanceMatrix({
            origins: [document.getElementById("origin1").value],
            destinations: [loc.toString()],
            ....
            //loc is array of locations

API Considers all array elements as single location.

Answer 1

You are converting array to string, But the destination requires array as input.

service.getDistanceMatrix(
{
    origins: [document.getElementById("origin1").value],              
    destinations: [loc],   // .ToString converts array to string, Hence removed
    ....
    //loc is array of locations
