Can we change the ids of nodes and connectors added to the canvas?

Hi Sudhanshu,

The Node and connector id should be unique and could not be changed at runtime. However, you can use node’s addInfo property to add custom information in node. We have created a sample in which we define node’s addInfo property initially and shown how to get an addInfo property at runtime. This approach will help you to achieve your requirement.

Code example:

let nodes = [

{

id: "NewIdea",

// define custom information

addInfo: {id: 'NewIdea'},

},]

//get custom information at runtime

function getNode() {

//get nodes

let nodes= diagramInstance.nodes;

// iterate nodes

for(var i=0;i<nodes.length;i++){

let node = nodes[i];

//get a addinfo value;

let nodeId = node.addInfo.id;

if(nodeId = "yourid") {

// do your code

}
