当X和X1 的距离等于到Y和Y1它很容易的。
但是,如果X有什么区别说100像素和Y差异是273px?
When the distance between X and X1 is equal to that between Y and Y1 its easy. But what if the X difference is say 100px and Y diff is 273px?
作为新的JavaScript,我不想重新发明轮子!
此外,由于我学习,我不想使用jQuery或喜欢。我想纯JavaScript。
Being new to Javascript, I don't want to re-invent the wheel! Besides, since I'm learning, I do NOT want to use jQuery or the likes. I want pure javascript.

推荐答案
解决方法一:
function translate( elem, x, y ) {
var left = parseInt( css( elem, 'left' ), 10 ),
top = parseInt( css( elem, 'top' ), 10 ),
dx = left - x,
dy = top - y,
i = 1,
count = 20,
delay = 20;
function loop() {
if ( i >= count ) { return; }
i += 1;
elem.style.left = ( left - ( dx * i / count ) ).toFixed( 0 ) + 'px';
elem.style.top = ( top - ( dy * i / count ) ).toFixed( 0 ) + 'px';
setTimeout( loop, delay );
}
loop();
}
function css( element, property ) {
return window.getComputedStyle( element, null ).getPropertyValue( property );
}
