|
|
- * { x : ?, y : ? } OR Object with x and y properties
|
|
|
- * { left : ?, top : ? } OR Object with left and top properties
|
|
|
- * { l : ?, t : ? } OR Object with l and t properties
|
|
|
- * [ ?, ? ] OR Array where the first two element are the coordinates (first is x, second is y)
|
|
|
- * ? A single value which stays for both axis
|
|
|
- * A value can be a number, a string or a calculation.
|
|
|
- *
|
|
|
- * Operators:
|
|
|
- * [NONE] The current scroll will be overwritten by the value.
|
|
|
- * '+=' The value will be added to the current scroll offset
|
|
|
- * '-=' The value will be subtracted from the current scroll offset
|
|
|
- * '*=' The current scroll wil be multiplicated by the value.
|
|
|
- * '/=' The current scroll wil be divided by the value.
|
|
|
- *
|
|
|
- * Units:
|
|
|
- * [NONE] The value is the final scroll amount. final = (value * 1)
|
|
|
- * 'px' Same as none
|
|
|
- * '%' The value is dependent on the current scroll value. final = ((currentScrollValue / 100) * value)
|
|
|
- * 'vw' The value is multiplicated by the viewport width. final = (value * viewportWidth)
|
|
|
- * 'vh' The value is multiplicated by the viewport height. final = (value * viewportHeight)
|
|
|
- *
|
|
|
- * example final values:
|
|
|
- * 200, '200px', '50%', '1vw', '1vh', '+=200', '/=1vw', '*=2px', '-=5vh', '+=33%', '+= 50% - 2px', '-= 1vw - 50%'
|
|
|
- *
|
|
|
- * 2. Can be a HTML or jQuery element:
|
|
|
- * The final scroll offset is the offset (without margin) of the given HTML / jQuery element.
|
|
|
- *
|
|
|
- * 3. Can be a object with a HTML or jQuery element with additional settings:
|
|
|
- * {
|
|
|
- * el : [HTMLElement, jQuery element], MUST be specified, else this object isn't valid.
|
|
|
- * scroll : [string, array, object], Default value is 'always'.
|
|
|
- * block : [string, array, object], Default value is 'begin'.
|
|
|
- * margin : [number, boolean, array, object] Default value is false.
|
|
|
- * }
|
|
|
- *
|
|
|
- * Possible scroll settings are:
|
|
|
- * 'always' Scrolls always.
|
|
|
- * 'ifneeded' Scrolls only if the element isnt fully in view.
|
|
|
- * 'never' Scrolls never.
|
|
|
- *
|
|
|
- * Possible block settings are:
|
|
|
- * 'begin' Both axis shall be docked to the "begin" edge. - The element will be docked to the top and left edge of the viewport.
|
|
|
- * 'end' Both axis shall be docked to the "end" edge. - The element will be docked to the bottom and right edge of the viewport. (If direction is RTL to the bottom and left edge.)
|
|
|
- * 'center' Both axis shall be docked to "center". - The element will be centered in the viewport.
|
|
|
- * 'nearest' The element will be docked to the nearest edge(s).
|
|
|
- *
|
|
|
- * Possible margin settings are: -- The actual margin of the element wont be affect, this option affects only the final scroll offset.
|
|
|
- * [BOOLEAN] If true the css margin of the element will be used, if false no margin will be used.
|
|
|
- * [NUMBER] The margin will be used for all edges.
|
|
|
- *
|
|

|
+ * Scrolls to a given position or element.
|
|
|
+ * @param coordinates
|
|
|
+ * 1. Can be "coordinates" which looks like:
|
|
|
+ * { x : ?, y : ? } OR Object with x and y properties
|
|
|
+ * { left : ?, top : ? } OR Object with left and top properties
|
|
|
+ * { l : ?, t : ? } OR Object with l and t properties
|
|
|
+ * [ ?, ? ] OR Array where the first two element are the coordinates (first is x, second is y)
|
|
|
+ * ? A single value which stays for both axis
|
|
|
+ * A value can be a number, a string or a calculation.
|
|
|
+ *
|
|
|
+ * Operators:
|
|
|
+ * [NONE] The current scroll will be overwritten by the value.
|
|
|
+ * '+=' The value will be added to the current scroll offset
|
|
|
+ * '-=' The value will be subtracted from the current scroll offset
|
|
|
+ * '*=' The current scroll wil be multiplicated by the value.
|
|
|
+ * '/=' The current scroll wil be divided by the value.
|
|
|
+ *
|
|
|
+ * Units:
|
|
|
+ * [NONE] The value is the final scroll amount. final = (value * 1)
|
|
|
+ * 'px' Same as none
|
|
|
+ * '%' The value is dependent on the current scroll value. final = ((currentScrollValue / 100) * value)
|
|
|
+ * 'vw' The value is multiplicated by the viewport width. final = (value * viewportWidth)
|
|
|
+ * 'vh' The value is multiplicated by the viewport height. final = (value * viewportHeight)
|
|
|
+ *
|
|
|
+ * example final values:
|
|
|
+ * 200, '200px', '50%', '1vw', '1vh', '+=200', '/=1vw', '*=2px', '-=5vh', '+=33%', '+= 50% - 2px', '-= 1vw - 50%'
|
|
|
+ *
|
|
|
+ * 2. Can be a HTML or jQuery element:
|
|
|
+ * The final scroll offset is the offset (without margin) of the given HTML / jQuery element.
|
|
|
+ *
|
|
|
+ * 3. Can be a object with a HTML or jQuery element with additional settings:
|
|
|
+ * {
|
|
|
+ * el : [HTMLElement, jQuery element], MUST be specified, else this object isn't valid.
|
|
|
+ * scroll : [string, array, object], Default value is 'always'.
|
|
|
+ * block : [string, array, object], Default value is 'begin'.
|
|
|
+ * margin : [number, boolean, array, object] Default value is false.
|
|
|
+ * }
|
|
|
+ *
|
|
|
+ * Possible scroll settings are:
|
|
|
+ * 'always' Scrolls always.
|
|
|
+ * 'ifneeded' Scrolls only if the element isnt fully in view.
|
|
|
+ * 'never' Scrolls never.
|
|
|
+ *
|
|
|
+ * Possible block settings are:
|
|
|
+ * 'begin' Both axis shall be docked to the "begin" edge. - The element will be docked to the top and left edge of the viewport.
|
|
|
+ * 'end' Both axis shall be docked to the "end" edge. - The element will be docked to the bottom and right edge of the viewport. (If direction is RTL to the bottom and left edge.)
|
|
|
+ * 'center' Both axis shall be docked to "center". - The element will be centered in the viewport.
|
|
|
+ * 'nearest' The element will be docked to the nearest edge(s).
|
|
|
+ *
|
|
|
+ * Possible margin settings are: -- The actual margin of the element wont be affect, this option affects only the final scroll offset.
|
|
|
+ * [BOOLEAN] If true the css margin of the element will be used, if false no margin will be used.
|
|
|
+ * [NUMBER] The margin will be used for all edges.
|
|
|
+ *
|
|
|
+ * @param duration The duration of the scroll animation, OR a jQuery animation configuration object.
|
|
|
+ * @param easing The animation easing.
|
|
|
+ * @param complete The animation complete callback.
|
