How to Update Node and Treeview Content in JavaScript Diagram?

The TreeView component is a graphical control that displays a hierarchical structure of nodes. Syncfusion® provides support for TreeView in JavaScript Diagram.
To update nodes and TreeView content at runtime, we can use the Dialog component to update both nodes and TreeView nodes.

Define the Dialog component in the HTML.

var dialog = new ej.popups.Dialog({
 footerTemplate: `<input id="inputValue" class="e-input" aria-label="Message" type="text" placeholder="Enter your node name here!"/>
       <button id="sendButton" class="e-control e-btn e-primary" data-ripple="true">Update</button>
       <button id="cancelButton" class="e-control e-btn e-primary" data-ripple="true" >Cancel</button>`,
 showCloseIcon: true,
 visible: false,
 width: '200',
 height: '200',
});

dialog.appendTo('#dialog'); 

How to update the content of a node and TreeView.

1. The dialog box will get triggered upon double-clicking the diagram nodes.
2. Edit the input area of the dialog box, and by using the Update button, we can update both the nodes and TreeView content.

function send() {
 let getContent = document.getElementById('inputValue');
 let content = getContent.value;
 diagram.selectedItems.nodes[0].annotations[0].content = content;
 let data = workingData;
 let treeview = treeObj;
 let elementNodeId = diagram.selectedItems.nodes[0].id;
 setTimeout(function () {
   let tempData = data.filter((a) => a.Id === elementNodeId);
   treeview.updateNode(tempData[0].Id, content);
 }, 0);
 diagram.dataBind();
 dialog.visible = false;
}
