Mousemove callback event not showing which mouse button is pressed safari

Question

Im developing a HTML5 Player. It's working ok on all browser, except safari for osx. (This player is supposed to work only on desktop browser).

I'm having a problem with a seek bar e a volume bar.

Basically its a slider, but implemented with divs and stuff. I did the following.

Registered a callback on the element for the 'mousemove' event. When this callbacks is triggered, i check the event for buttons. When use safari, this attribute is always 'undefined'.

The code is very simple:

this.controls.$seekBar.on('mousemove', (function(_this){
            return function(event){
                if (event.buttons == 1) {
                    // Do some stuff
                }
            }
        })(this))
            .on('mousedown', (function(_this){
                return function(event){
                    if (event.buttons == 1) {
                        // Do some stuff
                    }
                }
            })(this));

Since it's a jQuery plugin, i need to use closures to pass the plugin context to the callback, but this isn't the problem. I tested without being a jQuery plugin and the same error happens.

You can simply modify your code like below:

   this.controls.$seekBar.on('mousemove', (function(_this){
        return function(event){
            var buttons = (e.buttons === undefined ? e.which : e.buttons);
            if (buttons == 1) {
                // Do some stuff
            }
        }
    })(this))
        .on('mousedown', (function(_this){
            return function(event){
                var buttons = (e.buttons === undefined ? e.which : e.buttons);
                if (event.buttons == 1) {
                    // Do some stuff
                }
            }
        })(this));

It will works for all browser you need.
