Note that if you want to scroll an element instead of the full window  elements don t have the scrollTo and scrollBy methods  You should   var el   document getElementById  myel       Or whatever method to get the element     To set the scroll el scrollTop   0  el scrollLeft   0      To increment the scroll el scrollTop    100  el scrollLeft    100    You can also mimic the window scrollTo and window scrollBy functions to all the existant HTML elements in the webpage on browsers that don t support it natively   Object defineProperty HTMLElement prototype   scrollTo         value  function x  y            el scrollTop   y          el scrollLeft   x             enumerable  false      Object defineProperty HTMLElement prototype   scrollBy         value  function x  y            el scrollTop    y          el scrollLeft    x             enumerable  false       so you can do   var el   document getElementById  myel       Or whatever method to get the element  again     To set the scroll el scrollTo 0  0       To increment the scroll el scrollBy 100  100     NOTE  Object defineProperty is encouraged  as directly adding properties to the prototype is a breaking bad habit  When you see it  -
