Question

I am trying to get a DynaTree (first use of it) working w/o luck - the "tree" just shows up as a regular HTML list. I'm sure it's something trivial but I'm not seeing it.

Here is my file structure: DynaTree project files

This is the page (result.jsp) that the tree is on:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
  <title>IDT HL7 Search Results</title>
  <link rel="stylesheet" type="text/css" href="css/messaging.css" />
  <link rel="stylesheet" type="text/css" href="css/ui.dynatree.css" />
  <script type="text/javascript" src="js/jquery-1.7.1.js"></script>
  <script type="text/javascript" src="js/jquery.dynatree.js"></script>
  <script type="text/javascript" src="js/jquery-ui-1.8.16.custom.min.js"></script>
  <script type="text/javascript" src="js/jquery.cookies.2.2.0.js"></script>
  <!-- Add code to initialize the tree when the document is loaded: -->
  <script type="text/javascript">
$(document).ready(function() {
    // Attach the dynatree widget to an existing <div id="tree"> element
    // and pass the tree options as an argument to the dynatree() 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"}
      ]
    });
    $("a").click(function() {
     alert("Hello world!");
    });
  });
  </script>

        <textarea rows="14" wrap="soft" readonly="readonly">

        </textarea>
     </fieldset>
   </div>
   <div class="clear-both"></div>
</div>
</body>
</html>

Any ideas? Thanks! Mark

Solution

You must include jquery and jquery-ui before dynatree

OTHER TIPS

I see you have mixed two examples at a time. You try to initiate dynatree on and javascript object in the same time. Use only one to initiate:

1) Leave unordered list, delete generation from script (like in http://wwwendt.de/tech/dynatree/doc/samples.html - Default)

<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) Leave javascript object, delete unordered list (like in http://wwwendt.de/tech/dynatree/doc/samples.html - init from JS object)

<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"}
      ]
    });
});
