You should look into ajax request in your web application. Ajax would let you send a request to web service.

jQuery AJAX[^] is the best way to make a call from client-side to the service.
Simple ajax call would be:

JavaScript

$.ajax({
  url: "your-service-url",
    cache: false,
    success: function(response){
    // response return from the URL
    },
    error: function(xhr){
    // always catch the error
        console.log(xhr.responseText);
    }
});
