CreateUiDefinition referencing functions

The functions to use when referencing outputs from the properties or context of a CreateUiDefinition file.

basics

Returns the output values of an element that is defined in the Basics step. Pass in the name of the element as a parameter to this function.

To get the output values of elements in other steps, use the steps() function.

The following example returns the output of the element named clusterName in the Basics step:

"[basics('clusterName')]"

The returned values vary based on the type of element that is retrieved.

location

Returns the location selected in the Basics step or the current context.

The following example returns a value like "westus":

"[location()]"

resourceGroup

The following example:

"[resourceGroup()]"

Returns the following properties:

{
    "mode": "New" or "Existing",
    "name": "{resourceGroupName}",
    "location": "{resourceGroupLocation}"
}

You can get any particular value with dot notation.

"[resourceGroup().name]"

steps

Returns the elements on a specified step. Pass in the name of the step as a parameter to this function. From the returned elements, you can get particular property values.
