在Flowchart.js中,可以使用以下方法来批量操作节点和连接:
var nodesData = [
{id: 'node1', label: 'Node 1'},
{id: 'node2', label: 'Node 2'},
{id: 'node3', label: 'Node 3'}
];
nodesData.forEach(function(nodeData) {
flowchart.addStep(nodeData.id, nodeData);
});
var connectionsData = [
{from: 'node1', to: 'node2'},
{from: 'node2', to: 'node3'},
{from: 'node3', to: 'node1'}
];
connectionsData.forEach(function(connectionData) {
flowchart.addConnection(connectionData.from, connectionData.to);
});
var nodesIds = ['node1', 'node2', 'node3'];
nodesIds.forEach(function(nodeId) {
flowchart.removeStep(nodeId);
});
var connectionsData = [
{from: 'node1', to: 'node2'},
{from: 'node2', to: 'node3'},
{from: 'node3', to: 'node1'}
];
connectionsData.forEach(function(connectionData) {
flowchart.removeConnection(connectionData.from, connectionData.to);
});
通过以上方法,可以实现对Flowchart.js中节点和连接的批量操作。
