今日分享一点干货。PHP中课程表的实现。，.php课程表

首先贴代码，代码贴完再细说：

前段HTML：

开始细说:先来一张效果图吧。编辑前：

　　　　　编辑中(点右上角编辑后)：

    加了一些定位跟背景色的变化。让用户有更好体验，

　 第一步： 在接这个需求的时候，首先我在想怎么去获取表格内的数据，我首先想到的是  利用for循环嵌套，而后加判断，把数据往定义好的数组里添加，但是后来一想那样的话会导致

数据正确没错，但是存的数据有问题我打个比方   data[]={

　　　　　　　　　　　　　　　　　　　　　　　　　data[1]={

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　data[1][1] = 0;

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　... ...

　　　　　　}

　　　　　　　　　　　　　　　　　　　data[2]={　　　　　　　data[2][0]= 1;

　　　　　　　　　　　　　　　　　　　　　　　　　　... ...

　　　　　　}

　　　　　　　... ...

　　}

　意思就是我按照行循环的时候, 因为第一行跟第五行 多了一个

的存在， 会导致我的下标是从1开始 而不是跟其他行一样从0开始。

  后来我想不这样做，我加一个独有的class，就有了   var kecbInput = $(".activeStu"); 这句话。 这句话的意思是获取所有class="activeStu" 的对象的集合。

  至于余下的循环写法 如果有看不懂的可以在文章里直接提问，就不细说了。

 

  第二步：写完获取值后，剩下的无非就是传值到后台了，思路是每一个学生有一张属于他自身独有的课程表。还是老方法 利用ajax传值。 在保存数据的时候，将数据保存成json格式进行存   储。

  第三步：传值到前台页面并展示， 其实这个地方 ,如果有不少同学说, 这个简单着呢，不就是for循环 利用js 控制显示嘛， 那么就证明你没有掌握php volist 标签的好用之处！

  利用volist  可以很轻松的如我贴出来的代码一样  将你想要赋的值 展现出来。

  很多东西其实都在贴出来的代码里了，我表达能力不是很好，或者说我对这些东西理解也没到一定的程度。

  本来我是想 可以分享一些思路给大家， 但是写着写着发现 ，其实也没什么好说的。 不就这样么。 但是我还是觉得发出来好些吧， 可能有些人需要呢？虽然简单也没花多长时间。但是我相 信不停的分享，可能你的感悟就更深一些。
