- * http://flesler.blogspot.com/2007/10/jqueryscrollto.html

- * @version 1.4
- *
- * @id jQuery.scrollTo
- * @id jQuery.fn.scrollTo
- * @param {String, Number, DOMElement, jQuery, Object} target Where to scroll the matched elements.
- *	  The different options for target are:
- *		- A number position (will be applied to all axes).
- *		- A string position ('44', '100px', '+=90', etc ) will be applied to all axes
- *		- A jQuery/DOM element ( logically, child of the element to scroll )
- *		- A string selector, that will be relative to the element to scroll ( 'li:eq(2)', etc )
- *		- A hash { top:x, left:y }, x and y can be any kind of number/string like above.
- * @param {Number} duration The OVERALL length of the animation, this argument can be the settings object instead.
- * @param {Object,Function} settings Optional set of settings or the onAfter callback.
- *	 @option {String} axis Which axis must be scrolled, use 'x', 'y', 'xy' or 'yx'.
- *	 @option {Number} duration The OVERALL length of the animation.
- *	 @option {String} easing The easing method for the animation.
- *	 @option {Boolean} margin If true, the margin of the target element will be deducted from the final position.
- *	 @option {Object, Number} offset Add/deduct from the end position. One number for both axes or { top:x, left:y }.
- *	 @option {Object, Number} over Add/deduct the height/width multiplied by 'over', can be { top:x, left:y } when using both axes.
- *	 @option {Boolean} queue If true, and both axis are given, the 2nd axis will only be animated after the first one ends.
- *	 @option {Function} onAfter Function to be called after the scrolling ends. 
- *	 @option {Function} onAfterFirst If queuing is activated, this function will be called after the first scrolling ends.
- * @return {jQuery} Returns the same jQuery object, for chaining.
- *
- * @desc Scroll to a fixed position
- * @example $('div').scrollTo( 340 );
- *
- * @desc Scroll relatively to the actual position
- * @example $('div').scrollTo( '+=340px', { axis:'y' } );
- *
- * @dec Scroll using a selector (relative to the scrolled element)
- * @example $('div').scrollTo( 'p.paragraph:eq(2)', 500, { easing:'swing', queue:true, axis:'xy' } );
- *
- * @ Scroll to a DOM element (same for jQuery object)
- * @example var second_child = document.getElementById('container').firstChild.nextSibling;
- *			$('#container').scrollTo( second_child, { duration:500, axis:'x', onAfter:function(){
- *				alert('scrolled!!');																   
- *			}});
- *
- * @desc Scroll on both axes, to different values
- * @example $('div').scrollTo( { top: 300, left:'+=200' }, { axis:'xy', offset:-20 } );

+ * Date: 9/11/2008
+ *
+ * @projectDescription Easy element scrolling using jQuery.
+ * http://flesler.blogspot.com/2007/10/jqueryscrollto.html
+ * Tested with jQuery 1.2.6. On FF 2/3, IE 6/7, Opera 9.2/5 and Safari 3. on Windows.
+ *
+ * @author Ariel Flesler
+ * @version 1.4
+ *
+ * @id jQuery.scrollTo
+ * @id jQuery.fn.scrollTo
+ * @param {String, Number, DOMElement, jQuery, Object} target Where to scroll the matched elements.
+ *	  The different options for target are:
+ *		- A number position (will be applied to all axes).
+ *		- A string position ('44', '100px', '+=90', etc ) will be applied to all axes
+ *		- A jQuery/DOM element ( logically, child of the element to scroll )
+ *		- A string selector, that will be relative to the element to scroll ( 'li:eq(2)', etc )
+ *		- A hash { top:x, left:y }, x and y can be any kind of number/string like above.
+ * @param {Number} duration The OVERALL length of the animation, this argument can be the settings object instead.
+ * @param {Object,Function} settings Optional set of settings or the onAfter callback.
+ *	 @option {String} axis Which axis must be scrolled, use 'x', 'y', 'xy' or 'yx'.
+ *	 @option {Number} duration The OVERALL length of the animation.
+ *	 @option {String} easing The easing method for the animation.
+ *	 @option {Boolean} margin If true, the margin of the target element will be deducted from the final position.
+ *	 @option {Object, Number} offset Add/deduct from the end position. One number for both axes or { top:x, left:y }.
+ *	 @option {Object, Number} over Add/deduct the height/width multiplied by 'over', can be { top:x, left:y } when using both axes.
+ *	 @option {Boolean} queue If true, and both axis are given, the 2nd axis will only be animated after the first one ends.
+ *	 @option {Function} onAfter Function to be called after the scrolling ends.
+ *	 @option {Function} onAfterFirst If queuing is activated, this function will be called after the first scrolling ends.
+ * @return {jQuery} Returns the same jQuery object, for chaining.
+ *
+ * @desc Scroll to a fixed position
+ * @example $('div').scrollTo( 340 );
+ *
+ * @desc Scroll relatively to the actual position
+ * @example $('div').scrollTo( '+=340px', { axis:'y' } );
+ *
+ * @dec Scroll using a selector (relative to the scrolled element)
+ * @example $('div').scrollTo( 'p.paragraph:eq(2)', 500, { easing:'swing', queue:true, axis:'xy' } );
+ *
+ * @ Scroll to a DOM element (same for jQuery object)
+ * @example var second_child = document.getElementById('container').firstChild.nextSibling;
+ *			$('#container').scrollTo( second_child, { duration:500, axis:'x', onAfter:function(){
+ *				alert('scrolled!!');
+ *			}});
+ *
+ * @desc Scroll on both axes, to different values
+ * @example $('div').scrollTo( { top: 300, left:'+=200' }, { axis:'xy', offset:-20 } );

Powiedz rodzicom o możliwości przekazania 1% podatku i przekonaj ich, że warto samodzielnie zadecydować, co stanie się z częścią ich podatków.

Dzięki uzyskanym w ten sposób środkom będziemy mogli opublikować na stronie Wolnych Lektur jeszcze więcej tekstów oraz dodać nowe narzędzia ułatwiające czytanie. Dzięki temu biblioteka będzie jeszcze bardziej przydatnym i przyjaznym miejscem w sieci.</p>
