load()

loads data from an external file

load?(url: string | DataProxy, driver?: object | string): Promise<any>;

Parameters:

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

Returns:

A promise of data loading.

Example

component.data.load("../common/data.xml", "xml");

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:

component.data.load(url).then(function(){
    //do something after load;
});

or

component.data.load(url);
component.data.loadData.then(function(){
    //do something after load;
});
// loadData executes a callback function after an asynchronous
// data loading has completed
