Help with Javascript

[jamiet757]

I have a script that uploads images. It uses PHP to process the images and determine if there is an error or not. I have it set up so that $error= the error message, but if $error="", $result says "Successfully Uploaded"

 

Here is the problem:

When file is uploaded, either a success icon or a failed icon appear next to the message. Here is how it is currently set up:

 

    fileComplete: function(file, response) {

        this.options.processResponse || this

        var json = $H(JSON.decode(response, true));

        if (json.get('result') == 'success') {

            file.element.addClass('file-success');

            file.info.set('html', json.get('size'));

        } else {

            file.element.addClass('file-failed');

            file.info.set('html', json.get('error') || response);

        }

    },

 

I got rid of the JSON part on the PHP side, because it was too complicated and unnecessary for what I need it to do. I am not very familiar with javascript, but I want it to give the class of either "file-failed" or "file-success" depending on what $error is. If $error is nothing, it needs to add the class "file-success", otherwise it needs to add "file-failed".

 

Does this make sense to anyone? I hope so.
