Question

Hi is there a way to detect SqueezeBox closed by user?

Answer 1

Squeezebox has an event for that.

this.fireEvent('onClose', [this.content]);

so when you make your squeezebox, just add:

SqueezeBox.initialize({
    onClose: function() {
        alert('dont close me');
    }, 
    other: 'options'
});

btw – this is really old. you should get a more upto date lightbox.
