save()

saves changes made in a tree collection to the server side

save(url: IDataProxy | string): void;

Parameters:

• url: object | string - the URL of a server side (or DataProxy object)

Example

diagram.data.save("http://userurl/");

The component will make an AJAX call and expect the remote URL to save data changes.

Data saving is asynchronous, so you need to return a promise - the result of the saving operation. To do this, use the saveData property that returns a "promise" object:

const data = new TreeCollection();
data.save(loader);
return data.saveData.then(function () {
    // now your data is saved
});

Use the isSaved() method to know whether the changes are saved:

diagram.data.saveData.then(function () {
    console.log(diagram.data.isSaved());
});
