How to Disable and Enable Editing Button Click in JavaScript Diagram?

To control the behaviors of the JavaScript Diagram, nodes and connectors, you can use constraints. DiagramConstraints allow you to enable or disable various behaviors, such as: page editing, bridging, zoom and pan, undo/redo, and tooltips.

If you want to enable or disable editing in the diagram with button click, you can toggle the DiagramConstraints.PageEditable property.This will allow you to switch between enabling or disabling page editing dynamically.

Here’s an example of how to enable or disable page editing using the diagram’s constraints
You need to add buttons in your template to toggle the editing of the diagram

<input type="button" value="enable Editing" id="enable" />
   <input type="button" value="disable Editing" id="disable" /> 

document.getElementById('enable').onclick = function() {
     diagram.constraints = ej.diagrams.DiagramConstraints.Default;
 };
 document.getElementById('disable').onclick = function() {
     diagram.constraints = ej.diagrams.DiagramConstraints.Default &~ ej.diagrams.DiagramConstraints.PageEditable;
 };
