核心代码：
复制代码 代码如下:
$("#result").text(isOverlap("one","two")+","+isOverlap("one","three")+","+isOverlap("two","three"));
function isOverlap(idOne,idTwo){
var objOne=$("#"+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 > topOne && topTwo < topOne+heightOne,
rightTop = leftTwo+widthTwo > leftOne && leftTwo+widthTwo < leftOne+widthOne
&& topTwo > topOne && topTwo < 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;
return leftTop || rightTop || leftBottom || rightBottom;
}
原理很简单，就是判断一个元素的四个点是否在另一个元素内部。

RTX 5090要首发 性能要翻倍！三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB，每个模块容量为2GB。其速度预设为32 Gbps（PAM3），但也可以降至28 Gbps，以提高产量和初始阶段的整体性能和成本效益。
据三星表示，GDDR7内存的能效将提高20%，同时工作电压仅为1.1V，低于标准的1.2V。通过采用更新的封装材料和优化的电路设计，使得在高速运行时的发热量降低，GDDR7的热阻比GDDR6降低了70%。
