本文实例讲述了JavaScript实现鼠标点击后层展开效果的方法。分享给大家供大家参考。具体分析如下:
这段JavaScript代码可实现鼠标点击后层展开的功能,代码稍嫌复杂,重在学习研究,有兴趣的可以修改简化一下。

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%。
