私は1.3.2でうまく機能し、1.7.1で壊れているコードを持っていますが、コードが正しくない場合は誰でも私に何を指摘できますか?
(function($){
$.fn.extend({
autoscroll: function(options) {
return this.each(function() {
var $this = $(this);
$this.css({overflow:'hidden'});
if(options == 'horizontal') $this.mousemove(function(e) {
var width = $this.width();
$this.attr({ scrollLeft: ($this.attr('scrollWidth')-width)*(0.5-Math.cos(Math.PI*(e.pageX-$this.offset().left)/width)/2) });
});
else if(options == 'vertical') $this.mousemove(function(e) {
var height = $this.height();
$this.attr({ scrollTop: ($this.attr('scrollHeight')-height)*(0.5-Math.cos(Math.PI*(e.pageY-$this.offset().top)/height)/2) });
});
else if(options == 'both') $this.mousemove(function(e) {
var width = $this.width(), height = $this.height();
$this.attr({ scrollLeft: ($this.attr('scrollWidth')-width)*(0.5-Math.cos(Math.PI*(e.pageX-$this.offset().left)/width)/2), scrollTop: ($this.attr('scrollHeight')-height)*(0.5-Math.cos(Math.PI*(e.pageY-$this.offset().top)/height)/2) });
});
else $this.mousemove(function(e) {
var width = $this.width(), height = $this.height();
$this.attr({ scrollLeft: ($this.attr('scrollWidth')-width)*(0.5-Math.cos(Math.PI*(e.pageX-$this.offset().left)/width)/2), scrollTop: ($this.attr('scrollHeight')-height)*(0.5-Math.cos(Math.PI*(e.pageY-$this.offset().top)/height)/2) });
});
});
}
});
})(jQuery);
