You may call this JS function to check if file exists on the Server:

function doesFileExist(urlToFile)
{
    var xhr = new XMLHttpRequest();
    xhr.open('HEAD', urlToFile, false);
    xhr.send();

    if (xhr.status == "404") {
        console.log("File doesn't exist");
        return false;
    } else {
        console.log("File exists");
        return true;
    }
}
