Hi,

I want to make sure the connectors are connected to the nodes. I mean I want to validate all connectors have target process and source process. how can I validate in front-end?

Thanks.

Hi Aung,

The connectors sourceID and targetID properties are used to determine the connection established between the sourceNode and targetNode respectively. These properties will have a node id. Please refer to a code example below.

Code example:

//create button

//method called on button click

function getConnectors() {

var diagram = document.getElementById("diagram").ej2_instances[0];

//get connectors in diagram

var connectors = diagram.connectors;

//iterate connectors

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

var connector = connectors[i];

//get sourceNode id

console.log(connector.sourceID);

//get targetNode id

console.log(connector.targetID);

}

Regards,

Shyam G
