自定义节点

参考示例：自定义节点

创建代码

<ul id="tree1" class="mini-tree" url="../data/tree.txt" style="width:200px;padding:5px;" 
    showTreeIcon="true" textField="text" idField="id" 
    ondrawnode="onDrawNode" showCheckBox="true"
    >        
</ul>

此时，我们监听了“drawnode”事件。

drawnode 事件

function onDrawNode(e) {
    var tree = e.sender;
    var node = e.node;

    var hasChildren = tree.hasChildren(node);

    //所有子节点加上超链接
    if (hasChildren == false) {
        e.nodeHtml = '<a href="http://www.miniui.com/api/' + node.id + '.html" target="_blank">' + node.text + '</a>';
    }

    //父节点高亮显示；子节点斜线、蓝色、下划线显示
    if (hasChildren == true) {
        e.nodeStyle = 'font-weight:bold;';
    } else {
        e.nodeStyle = "font-style:italic;"; //nodeStyle
        e.nodeCls = "blueColor";            //nodeCls
    }

    //修改默认的父子节点图标
    if (hasChildren == true) {
        e.iconCls = "folder";
    } else {
        e.iconCls = "file";
    }

    //父节点的CheckBox全部隐藏
    if (hasChildren == true) {
        e.showCheckBox = false;
    }
}
