load()

Description

Loads data from an external file

Usage

load(
    url: string | object,
    driver?: object | string
): promise;

Parameters

• url - (required) the URL of an external file or DataProxy with the URL configured
• driver - (optional) DataDriver or type of data ("json", "csv", "xml"), "json" by default

Returns

The method returns a promise of data loading

Example

const diagram = new dhx.Diagram("diagram_container", {
    type: "default"
});
diagram.data.parse(data);

diagram.data.load("../common/data.json");

Details

The component will make an AJAX call and expect the remote URL to provide valid JSON data.

Data loading is asynchronous, so you need to wrap any after-loading code into a promise:

diagram.data.load("../some/data").then(() => {
    diagram.selection.add(123);
});
