[原创] 扩展jquery-treegrid插件, 实现勾选功能和全删按钮.

新上手一个项目, 因而正好想学习下bootstrap, 所以就采用asp.net mvc + bootstrap来做.  因为需要TreeGrid的控件, 本来想用easyUI、LingerUi、DWZ, 但显示效果总觉得不协调. 搜来搜去, 发现了牛人写的 jquery-treegrid, 所以就参考这园子里的两篇文章开始做:

JS组件系列——自己动手封装bootstrap-treegrid组件:      http://www.cnblogs.com/landeanfen/p/6776152.html

JS组件系列——封装自己的JS组件,你也可以:     http://www.cnblogs.com/landeanfen/p/5124542.html

 

 

这次目的是扩展jquery-treegrid插件, 实现checkbox的全选、单选, 也照着上文添加了ajax远程获取数据的功能. 虽然后来发现了Kendo UI, 但本着学习的目的, 还是完成了这次的插件扩展功能.

由于常年没有接触过前端, 所以jquery基本语法都磕磕绊绊更别说扩展插件了, 边摸索边做.  待我改完一版本, 才能理解了jquery-treegrid插件的作者真的牛掰:

1. jquery-treegrid思想: 没有硬编码的html, 全部通过css样式实现. 像树形结点的维护、结点的打开与折叠状态, 都是由写在TR元素上的css来实现. 也倒是jquery本身不熟吧, 我第一次见这么少的html来实现的jQuery控件.

2. 插件的结构: 跟上面的总体结构类似, 都是  method{}方法集合、$.fn.treegrid扩展、default{}默认参数对象. 其通过初始化函数initTree来开始渲染table元素, 通过保存控件容器(TreeContainer) -> 保存全局设置(Settings) -> 递归地初始化结点(initNode) -> 为每个结点添加事件(intExpander、initIdent、initEvents、initState、initChangeEvent、initSettingsEvents)来完成最终功能. 整体上有点面向对象的意味, 跟之前自己写的JS差距甚大.

 

 

刚开始我也是照着前面两篇的文章来实现了基本的样子, 当我快做完的时候才理解了jquery-treegrid控件作者的思路. 根据前两篇文章的思路, 就是在初始化方法中, 通过ajax获取数据, 然后在回调方法中拼接HTML表格, 来完成对jquery-treegrid的远程取数据的扩展. 当我基本理解了jQuery-treegrid作者的思想以后, 尝试将上面的代码改成: 在获取远程数据后, render表格(renderHeader、RenderBody、递归的生成List类型的Tr和Tree类型的Tr)、之后初始化Header(初始化checkAll、DelAll、操作列)、再往后初始化结点(initExpander、initIndent、initCheck、initOperation、initEvnets、initState、initChangeEvent、initSettingsEvents).   所有操作(如:全选、全部选、直选部分)等操作, 也都是通过在Tr元素上附加css来实现的.

 

总结实现过程的砍儿:

1. 理解插件开发思路及手段, 为什么采用如此结构来组织插件.

2. 控件状态的处理其实是使用了cookie, 用jquery-cookie来实现的.

3. 特别要理解This所代表的对象, 可以在调试界面一步步验证this所代表的对象.

4. 关于原jquery-treegrid插件的封装, $(this).原控件('方法名','参数')来封装. 这里需要注意的是: 在我们自己的扩展代码中, 关于状态保存、容器位置、设置保存等内容, 我都是通过对原控件的封装, 将这些数据写在同一个位置, 以便实现我们自己的控件和原控件之间的数据共享.

5. 默认default对象之中的方法的调用: 1. 通过settings.方法名.apply(this, '参数')来调用. 2. 通过我们扩展控件中封装的, $(this).treegridExt('getSetting','方法名').apply(this,'参数')来实现的.

6. 注意参数的问题: 有时用this、有时用$(this)、有时用$($(this).treegridExt('方法名'))、有使用[$(this)], 有时用apply(this)、还有时用apply($(Elem))等等. 决定使用哪种方式的的根本原因就是 this所代表的当前对象. 根据当前对象的不同, 来变换几种参数形式.

 

 

最后, 废话不多说, 上代码. 注意: 改代码只实现了全选、全不选、选子项、以及子项变更后对父级选项的调整.  之后没有再深入编码, 因为项目还是比较紧, 考虑一个个控件自己搞还是太费劲了, 准备采用Kendo控件来完成项目, 此Demo仅作为学习jquery和扩展其插件的相关知识为目的. 顺带对老大说声抱歉, 多耽误2,3天(算上端午的话可能是5天).
