ExternalWeb Component

An ExternalWeb component embeds an external web page in a Web App. An ExternalWeb component is created with the <ExternalWebComponent> element.

If the host of the web page prohibits embedding, for example, by including an appropriate HTTP response header, that web page cannot be embedded in a Web App.
Note that embedded websites may store and use cookies on the end device.

The following attributes can be defined for the <ExternalWebComponent> element:

`displayName`	Display name of the component in the menu. Translatable Data Binding possible Possible values: Any string
`path`	Required. Unique URL of the component, visible in the browser address bar. Possible values: String of alphanumeric characters (no umlauts, dots, etc.)

Example

URL in ExternalWeb

The following example in the .wad creates an ExternalWeb component:

XML

<ExternalWebComponent 
	path="ExternalWebUrl"
	displayName="SoftProject Website"
	url="https://www.softproject.de" />

URL via Technical Process

The following example in the .wad creates an ExternalWeb component:

XML

<ExternalWebComponent 
	path="ExternalWebUrl"
	displayName="SoftProject Website"
	process="provideURL.wrf" />

The provideURL.wrf Technical Process returns the following output, which sets the URL:
