Examples

Example 1: Preload data

Goal: Creat a preLoad action loading a PDF file.

To achieve this the following code can be used:

{
  "type": "preLoad",
  "params": {
    "type": "pdf",
    "urls": [
      "https://fabrik19.de/wp-content/uploads/2021/07/Produktkatalog-Fabrik19-eGovernment.pdf"
    ],
    "async": true,
    "onSuccess": "preloadSuccess",
    "onError": "preloadError"
  }
}

The urls parameter specifies the path to the data to be preloaded.

Result:

A preLoad action has been created.
