How to set a link url or controller action in a tree childnode
posted

Hi, I´m in a mvc .net project and I have no idea how to set the <a href> property tag in the <li> with the Json function, how can I change the '#' in the href and the target?

My Cshtml have the tree menu like this elements:

<ul style="" data-depth="2">

      <li class="ui-igtree-node ui-igtree-node-nochildren" data-path="0_2_0" data-value="000000000000000000000000" data-role="node">

                <a href="#" target="_self" class="ui-corner-all">Lorem Ipsum dolor sit amet</a>

    </li>

</ul>

I load the tree menu with a Json like this structure:

My Json is like:

$(function () {

var data = [];
$.post("LoadMenuTree", {}, function (menu, status) {
data = menu;

// Initialize igTree
$("#tree").igTree({
       dataSourceType: "json",
      dataSource: data,
      initialExpandDepth: 0,
      bindings: {
                      textKey: "menu_string",
                      valueKey: "id",
                      childDataProperty: "menuDto",
                      }

           });

      });
});

    To dynamically set the href and target attributes in a tree menu loaded via JSON, you can modify the data processing within your JavaScript. Since you’re using a JSON object to populate your tree, you can include the url property directly in your JSON and adjust the binding settings accordingly.

    Here's a quick approach:

    Add the link URL to each JSON menu item, such as:

    json
    Copy code
    {
    "menu_string": "Lorem Ipsum dolor sit amet",
    "id": "000000000000000000000000",
    "url": "/targetPage",
    "target": "_self"
    }
    Bind the url and target properties using JavaScript after retrieving the data in your igTree setup. For example:

    javascript
    Copy code
    $(function () {
    $.post("LoadMenuTree", {}, function (menu) {
    $("#tree").igTree({
    dataSourceType: "json",
    dataSource: menu,
    initialExpandDepth: 0,
    bindings: {
    textKey: "menu_string",
    valueKey: "id",
    childDataProperty: "menuDto",
    urlKey: "url", // Bind the URL here
    targetKey: "target" // Bind the target here
    },
    nodeContentTemplate: "<a href='${url}' target='${target}'>${menu_string}</a>"
    });
    });
    });
    This way, your links should dynamically populate as specified in the JSON. Additionally, if you’re working on a creative project like Incredibox Sprunki and exploring innovative user interface elements, similar JSON-based tree setups can streamline dynamic content display for improved interactivity.
