dhtmlxtree学习笔记一(快速入门)

由于工作需要,写一个树状结构,本打算使用ext,但是api过多,内容过于复杂,学习成本比较高,最终还是选择放弃了。最终选择了dhtmlxtree 这个插件,下面我简单介绍一下自己学习的东西。

?

从网上下载dhtmlxtree 地址是?http://dhtmlx.com/docs/products/dhtmlxTree/

?

解压zip包,进入dhtmlxTree目录下面的samples中的内容是无法显示效果的,原因我还不是很清楚,为了能看到sample效果,我们可以放到web容器中(如tomcat),然后通过web容器访问就可以了

?

快速入门

1、把[解压dthmlxtree.zip包目录]dhtmlxTree\samples下的common目录考入到web工程中

2、把如下文件也引入到web工程中

? ? 1)dhtmlxcommon.js

? ? 2)dhtmlxtree.js?

? ? 3)dhtmlxtree.css ??---- 前三个js是创建tree的基础js,必须要引入的

? ? 4)dhtmlxtree_json.js ---- 使用json数据需要引入的js

? ? 5)dhtmlxtree_start.js ---- 如何是想对网页中的标签改成tree格式,就需要引入这个js

?

引入的结构如下图所示:

引入本地的xml文件
