代码如下:
function offsetTop( elements ){
var top = elements.offsetTop;
var parent = elements.offsetParent;
while( parent != null ){
top += parent.offsetTop;
parent = parent.offsetParent;
};
return top;
};
function offsetLeft( elements ){
var left = elements.offsetLeft;
var parent = elements.offsetParent;
while( parent != null ){
left += parent.offsetLeft;
parent = parent.offsetParent;
};
return parent;
};
获取offsetTop和offsetLeft值的js代码(兼容
