Is URL Parameter Set
This property returns true if the given
URL Parameter has been specified in the URL of the
browser.
In this example, the element will be visible when the URL looks like this:
http://localhost:8512/runtime/MyHMI?enableAdvancedSettings
And the element will be hidden when the URL looks like this:
http://localhost:8512/runtime/MyHMI
Value is Ignored
- HELIO will only check to see if the parameter exists, not what its value is.
- Therefore, an actual value does not need to be set.
If you want to use the actual value of the parameter, check out URL Parameter Value.
