jQuery_jquery를 기반으로 두 요소가 겹치는지 확인하는 코드

核心代码：

复aze代码 代码如下:

$("#result").text (isOverlap("1","2") "," isOverlap("1","3") "," isOverlap("2","3"));
function isOverlap(idOne,idTwo){
var objOne=$("#" idOne),
objTwo=$("#" idTwo),
offsetOne = objOne.offset(),
offsetTwo = objTwo.offset(),
topOne=offsetOne.top,
topTwo=offsetTwo.top,
leftOne=offsetOne.left,
leftTwo=offsetTwo.left,
widthOne = objOne.width(),
widthTwo = objTwo.width(),
heightOne = objOne.height(),
heightTwo = objTwo.height();
var leftTop = leftTwo > leftOne && leftTwo < leftOne widthOne
&& topTwo > 탑원 && 탑투 < topOne heightOne,
rightTop = leftTwo widthTwo > leftOne && leftTwo widthTwo < leftOne widthOne
&& topTwo > 탑원 && 탑투 < topOne heightOne,
leftBottom = leftTwo > leftOne && leftTwo < leftOne widthOne
&& topTwo heightTwo > topOne && topTwo heightTwo < topOne heightOne,
rightBottom = leftTwo widthTwo > leftOne && leftTwo widthTwo < leftOne widthOne
&& topTwo heightTwo > topOne && topTwo heightTwo < topOne heightOne;
왼쪽으로 돌아가기Top || 오른쪽상단 || 왼쪽아래 || 오른쪽하단;
}

원리很简单，就是判断一个元素的另一个元素内内否。
