在Web 应用项目中,实现一对多录入的数据管理功能是一项常见的应用。因此可以实现一个相对轻量化的设计实现表格的录入,为保证功能的可用性、界面友好性,总体的需求如下: 1、数据网格可以动态的添加行,行可以提供输入框、选择框的控件进行录入。 2、数据网格可以删除选中的行。 3、数据网格可以上下移动选中的行重新进行...

a = 110 //使用索引赋值 _mytable["c"]=139 1 2 3 4 5 6 7 8 9 思考一下:如果现在定义了一个table a,将table a赋值给table b,此时它们的内存情况是什么样呢? ab都会指向同一个内存块,如果a设置为nil,b依旧能访问该内存块的元素,直到b设置为nil后,Lua的垃圾回收机制会清理相应的内存。所以当b...
