jQuery zTree插件使用

83493467 2014-01-13

zTree插件的基本功能全部实现:

前段时间工作需要对zThree进行了研究:对照zTree的API进行使用

 动态链接数据库:实现增删改查,和单个多个节点拖拽功能,使用Ajax和数据库动态更新。

首次加载

   $.fn.zTree.init($("#treeDemo2"), setting2, zNodes2);
   $.fn.zTree.init($("#treeDemo"), setting, zNodes);

 如果是现实多颗树需要多个setting和zNodes使用

addDiyDom  用于在节点上固定显示用户自定义控件

addHoverDom用于当鼠标移动到节点上时,显示用户自定义控件,显示隐藏状态同 zTree 内部的编辑、删除按钮
 removeHoverDom用于当鼠标移出节点时,隐藏用户自定义控件,显示隐藏状态同 zTree 内部的编辑、删除按钮
