Troubleshooting Jquery and Play Framework 2 JavaScript router issues

However, I'm now interested in sending a request to the server, querying a database, and receiving a response back via AJAX to update an image or change text dynamically.

What would be the recommended approach for achieving this?

At the moment, my setup includes:

A controller function:

public static Result delete(Long id) {
    //...
    return ok();
}

The corresponding view:

<script type="text/javascript">
    $("#delete").click(function() {
        var id = $(this).attr("data-id");
        alert(id);
        jsRoutes.controllers.Items.delete(id).ajax({});
        return false;
    });
</script>

Answer №1

To begin, it is necessary to send a Json response back to the browser. Take a look at the official documentation for guidance. Next, you will need to manage the response in JavaScript using the following approach:

jsRoutes.controllers.Items.delete(id).ajax({
  success: function(datafromserver) {
   // Implement your logic here if the operation is successful        
 },
 error:function(xhr, status, error) {
    // Handle any exceptions that occur
 }
});
