Contains the value of the mouse position relative to the left edge of the viewable window (X-axis).

In the example below we show two new messages in the 'p' elements below every time the mouse moves over the image with the id of 'curry1'.

When the mouse moves while over the image, we trigger off the mousemove JavaScript event on the 'image'. This then fires off the $('#curry1').mousemove(function(){}) code which outputs the messages.


$(function(){
  $('#curry1').mousemove(function(event) {
    var pageCoords = '(' + event.pageX + ', ' + event.pageY + ' )';
    var viewableCoords = '(' + event.clientX + ', ' + event.clientY + ' )';
    $('#animspan1').text('( event.pageX, event.pageY ) : ' + pageCoords);
    $('#animspan2').text('( event.clientX, event.clientY ) : ' + viewableCoords);
  });
  $('#curry1').mousemove();
});
