下面的例子將結(jié)合項(xiàng)目實(shí)際運(yùn)用來使用Jquery.TreeView,當(dāng)然在使用控件樹需要現(xiàn)在相應(yīng)的js文件
下面就把我生成的TreeView展現(xiàn)給大家看看希望對(duì)大家有所幫助！在使用之前需要下載控件樹的js文件和Css樣式

介紹一下表結(jié)構(gòu)

M_ID M_Name M_ParentID M_URL M_Sort

然后新建一個(gè)網(wǎng)站，在新建的網(wǎng)站下添加CSS文件夾和js文件夾分別用于存放Css樣式和JS，同時(shí)再添加一個(gè)image文件夾用于存放TreeView的圖片
接著我們就開始實(shí)現(xiàn)我們的功能了！
