本文实例讲述了JQuery实现简单的复选框树结构图。分享给大家供大家参考,具体如下: 这是自己写的简单树结构图,实现的功能有: 1.最左边的按钮实现子目录的隐藏和显示 2.点击父节点的复选框选中后,父节点下的所有的子节点也选中;父节点未选中,则下面的所有的子节点也取消选中(全选和全不选) 3.选中一个子节点时相应的父节点也选中;当所有的子节点都没有选中时,父节点也取消选中 这是实现的最简单的功能。下面来具体的谈谈具体的实现: 1.引入库 所有的这些操作都是通过JQuery来实现的,所以首先要引入JQuery库,可以到官网下载JQuery库,也可以通过CDN的方式来引用,这里我是通过CDN

They argue against a fair Discussion of popular Prejudices, because, say they, tho’they would be found without any reasonable Support, yet the Discovery might be productive of the most dangerous Consequences.

技术说明文档:基于分理论的电树枝物理现象的计算机仿真研究
针对现阶段基于图像检测的板识别在缺陷的检出率普遍较低以及检测速度慢等问题,文中提出了一种基于计算机图像处理的板识别系统,其通过直方图均衡化与高帽变换对初始图像进行处理,并通过边缘检测算法提取轮廓,然后利用BP神经网络分类器进行缺陷识别与分类。其在实验及实际工业生产中,均具有较高的识别率,可达到约90%,且还具有较好的板识别效果。

在已知船舶K、T、δ的情况下,根据船舶操纵线性响应方程分析了阶跃操舵、线性操舵下船舶的运动,并将其应用到Z操舵中,预报了船舶的运动.在小舵角情况下,预报结果与实船测试结果一致.该方法亦可用于鱼雷、潜艇的水平面操纵性预报.
