JQuery ZTree使用方法詳解 719 2024-02-06

JQuery ZTree簡單使用

@(JavaScript)[jQuery, ztree, 入門]

基本概述

zTree 是一個依靠 jQuery 實現(xiàn)的多功能 “樹插件”。優(yōu)異的性能、靈活的配置、多種功能的組合是 zTree 最大優(yōu)點。專門適合項目開發(fā)，尤其是樹狀菜單、樹狀數(shù)據(jù)的Web顯示、權限管理等等。

zTree 是開源免費的軟件（MIT 許可證）。在開源的作用下，zTree 越來越完善，目前已經(jīng)擁有了不少粉絲，并且今后還會推出更多的 zTree 擴展功能庫，讓 zTree 更加強大。 ——參考《百度百科》

官網(wǎng)：zTree官網(wǎng)

PS：zTree的官方API文檔和demo挺詳細的，值得一讀。
