openatfirstvisit.txt

javascript 写的动态树,里面有两个示例文件一看就会用。

<div class="folder" id="a1">Node 1</div>
<div class="folder" id="a2">Node 2</div>
<div class="folder" id="a3">Node 3</div>

var tree = new DynamicTree("tree");
tree.init();
if (!tree.cookie.get("tree-visited") && !tree.cookie.get("opened")) {
    tree.open("a1");
    tree.open("a2");
    tree.open("a3");
    tree.cookie.set("tree-visited", 1, 3600*24*365);
}
