Cytsocape.js can't create edges in for loop
I'm creating chart with nodes and edges. Once I created nodes, I can't create the associated edges without getting those kind of errors :
Can not create edge
5134fb65-b30f-4947-9870-cc909e293e21with nonexistant sourcePeter
My code :
var myJSONdata = info;
var cy = window.cy = cytoscape({
container: document.getElementById('cy'),
boxSelectionEnabled: false,
autounselectify: true,
style: [
{
selector: 'node',
style: {
'content': 'data(id)',
'text-opacity': 0.5,
'text-valign': 'center',
'text-halign': 'right',
'shape': 'hexagon',
'label': 'data(label)',
'background-color': '#11479e'
}
},
{
selector: 'edge',
style: {
'curve-style': 'bezier',
'width': 4,
'target-arrow-shape': 'triangle',
'line-color': '#9dbaea',
'target-arrow-color': '#9dbaea'
}
}
],
// elements: {
// nodes: [
// { data: { id: 'Peter' } },
// { data: { id: 'Claire' } },
// { data: { id: 'Mike' } },
// { data: { id: 'Rosa' } }
// ],
// edges: [
// { data: { source: 'Peter', target: 'Claire' } },
// { data: { source: 'Claire', target: 'Mike' } },
// { data: { source: 'Mike', target: 'Rosa' } }
// ]
// }
});
var array = ;
// Create nodes
for (var i = 0; i <= myJSONdata.length - 1; i++) {
array.push({
group: 'nodes',
data: {
id: i,
label: myJSONdata[i].name
}
}
);
}
// Create edges
for (var i = 0; i <= myJSONdata.length - 1; i++) {
var source = myJSONdata[i].name;
array.push({
group: 'edges',
data: {
source: source,
target: myJSONdata[i].next_op_name
}
});
}
cy.add(array);
cy.layout({
name: 'circle'
}).run();
The "Create nodes" part is working, but the "Create edges" is not.
I tried the solution here but it does not work.
Actually I want to read data from JSON file to create the chart.
I can do it with :
elements: {
nodes: [
{ data: { id: 'Peter' } },
{ data: { id: 'Claire' } },
{ data: { id: 'Mike' } },
{ data: { id: 'Rosa' } }
],
edges: [
{ data: { source: 'Peter', target: 'Claire' } },
{ data: { source: 'Claire', target: 'Mike' } },
{ data: { source: 'Mike', target: 'Rosa' } }
]
}
But I want to automate it according to the JSON file in input.
This is my JSON file :
info = [
{
"name": "Peter",
"next_op_name": "Claire",
}, {
"name": "Claire",
"next_op_name": "Mike",
}, {
"name": "Mike",
"next_op_name": "Rosa",
}, {
"name": "Rosa",
"next_op_name": "Peter",
}
];
I can't understand what is wrong.

The source and target fields in the edge are the IDs of nodes, not labels.
When you create the nodes, you need to set id to myJSONdata[i].name as well.
