Code of the framework itself:

 

// JavaScript Document/*** multi-object, any value motion frame obj: the object to be moved attr: the attribute to be changed iTarget: target point to be reached by the attribute value *** // function for retrieving the element attribute value */function getStyle (obj, attr) {if (obj. currentStyle) {return obj. currentStyle [attr];} else {return getComputedStyle (obj, false) [attr];} function startMove (obj, attr, iTarget) {clearInterval (obj. timer); obj. timer = setInterval (function () {var iCur = 0; if (attr = 'opacity ') {iCur = parseInt (parseFloat (getStyle (obj, attr) * 100 );} Else {iCur = parseInt (getStyle (obj, attr);} var iSpeed = (iTarget-iCur)/8; iSpeed = iSpeed> 0? Math. ceil (iSpeed): Math. floor (iSpeed); if (iCur = iTarget) {clearInterval (obj. timer);} else {if (attr = 'opacity ') {obj. style. filter = 'Alpha (opacity: '+ (iCur + iSpeed) +') '; obj. style. opacity = (iCur + iSpeed)/100 ;}else {obj. style [attr] = iCur + iSpeed + 'px ';}}, 30 );}
