How to bind click event to HTML button node in React Diagram?

First, create an HTML node with a button. In the React Diagram, a button for each HTML node must be provided either as string content or an ng-template to trigger the click event. Below is a code snippet demonstrating how to render the button using an ng-template:

<DiagramComponent
   id="diagram"
   ref={(diagram) => (diagramInstance = diagram)}
   width={'100%'}
   height={'645px'}
   nodes={nodes}
   getNodeDefaults={(node) => {
     node.width = 100;
     node.height = 100;
     return node;
   }}
   nodeTemplate={diagramTemplate.bind(this)}
   >
</DiagramComponent>

To trigger the click event on the button, add the click event inside the button div element. In the below sample, we have bound the click event and changed the shape to basic, and filled the node color.

 function diagramTemplate(props) {
   return (
     <div style={{ width: '100px', height: '100px', background: 'blue' }}>
       <button id="buttonClick" onClick={buttonClick}>
         Click
       </button>
     </div>
   );
 }
 
function buttonClick() {
   diagramInstance.nodes[0].shape = { type: 'Basic' };
   diagramInstance.nodes[0].style = { fill: 'red' };
   diagramInstance.dataBind();
 }
