jsTree树控件(基于jQuery, 超剽悍)[推荐]

jsTree是基于javascript的一个跨浏览器树控件，功能强大，而且是免费的。

1、支持基于HTML定义、Json、XML方式加载树节点

2、支持拖放，动态增加、删除、重命名树节点

3、支持复选框

4、支持复制、剪切、粘贴树节点，动态刷新树

5、提供足够的回调方法：

        beforechange: function() { log("About to change"); return true },
        beforeopen  : function() { log("About to open"); return true },
        beforeclose : function() { log("About to close"); return true },
        beforemove  : function() { log("About to move"); return true }, 
        beforecreate: function() { log("About to create"); return true }, 
        beforerename: function() { log("About to rename"); return true }, 
        beforedelete: function() { log("About to delete"); return true }, 
        onselect    : function() { log("Select"); },
        ondeselect  : function() { log("Deselect"); },
        onchange    : function() { log("Focus changed"); },
        onrename    : function() { log("Rename"); },
        onmove      : function() { log("Move"); },
        oncopy      : function() { log("Copy"); },
        oncreate    : function() { log("Create"); },
        ondelete    : function() { log("Delete"); },
        onopen      : function() { log("Open"); },
        onopen_all  : function() { log("Open ALL"); },
        onclose     : function() { log("Close"); },
        error       : function() { },
        ondblclk    : function() { log("Doubleclick"); TREE_OBJ.toggle_branch.call(TREE_OBJ, NODE); TREE_OBJ.select_branch.call(TREE_OBJ, NODE); },
        onrgtclk    : function() { log("Rightclick"); },
        onload      : function() { log("Tree loaded"); },
        onfocus     : function() { log("Tree got focus"); },
        ondrop      : function() { log("Foreign node dropped"); }

6、此外，还提供了详细的使用文档

        jsTree is a javascript based, cross browser tree component. It uses jQuery and Sarissa (optionally). jsTree is absolutely free (licensed same as jQuery - under both GPL and MIT - whichever suits your needs).

Currently supported browsers are: Internet Explorer 6 +, Mozilla Firefox, Safari 3, Opera 9+, Google Chrome. The latter three are not thoroughly tested. jsTree may also work with other browsers - please drop me a note if you performed some tests.

Key features

• Data sources:
  • predefined HTML - convert nested lists into a tree on the fly
  • JSON - provide a json object
  • XML - provide a nested structure or a flat (id -> parent_id) one
• Async loading - just provide an URL and the tree will request data as needed (works for XML & JSON sources)
• Open, close, rename, create, delete nodes (all with definable rules)
• Various callbacks (onchange, oncreate, ondelete, onload, etc …)
• Drag & drop support (definable with rules)
• Multiple select
• Localization - maintain the same tree in as many languages as you like
• Right-to-left support (supported in both supplied themes)
  
• Theme support (change icons, sizes, backgrounds, etc …)
• Animated open & close (configurable)
• Optional keyboard navigation
• multitree support - move/copy nodes form to tree to tree (definable with rules)
• also works as a jQuery plugin
