Question

我试图让DynaTree（第一次使用它）运行起来很幸运 - “树”只是显示为常规的HTML列表。我确定这是微不足道的，但我没有看到它。

这是我的文件结构： DynaTree project files

这是树所在的页面（result.jsp）：

    $("#tree").dynatree({
      onActivate: function(node) {
        // A DynaTreeNode object is passed to the activation handler
        // Note: we also get this event, if persistence is on, and the page is reloaded.
        alert("You activated " + node.data.title);
      },
      children: [

        {title: "Folder 2", isFolder: true, key: "folder2",

有什么想法吗？谢谢！标记

Answer 1

你必须在 dynatree之前包含jquery和jquery-ui

Answer 2

我看到你一次混合两个例子。您尝试在同一时间启动dynatree和javascript对象。仅使用一个来启动：

1）保留无序列表，从脚本中删除生成 （如http://wwwendt.de/tech/dynatree/doc/samples.html - 默认）

<div id="tree">
    <ul>
        <li>Orders
        <ul>
            <li>From Client
            <ul>
                <li> document 1.1.1</li>
                <li> document 1.1.2</li>
            </ul>
            </li>
            <li>To Lab
            <ul>
                <li>document 1.2.1</li>
                <li>document 1.2.2</li>
            </ul>
            </li>
        </ul>
        </li>
        <li> Results
        <ul>
            <li> From Lab
            <ul>
                <li>document 2.1.1</li>
                <li>document 2.1.2</li>
            </ul>
            </li>
            <li>To Client
            <ul>
                <li>document 2.2.1</li>
                <li>document 2.2.2</li>
            </ul>
            </li>
        </ul>
        </li>
    </ul>
</div>

$(document).ready(function() {
    $("#tree").dynatree();
});

2）保留javascript对象，删除无序列表 （比如在http://wwwendt.de/tech/dynatree/doc/samples.html - 来自JS对象的init）

<div id="tree"></div>

$(document).ready(function() {
$("#tree").dynatree({
      onActivate: function(node) {
        // A DynaTreeNode object is passed to the activation handler
        // Note: we also get this event, if persistence is on, and the page is reloaded.
        alert("You activated " + node.data.title);
      },
      children: [
        {title: "Item 1"},
        {title: "Folder 2", isFolder: true, key: "folder2",
          children: [
            {title: "Sub-item 2.1"},
            {title: "Sub-item 2.2"}
          ]
        },
        {title: "Item 3"}
      ]
    });
});

jQuery DynaTree无法正常工作
