CreateUiDefinition conversion functions

These functions can be used to convert values between JSON data types and encodings.

bool

Converts the parameter to a boolean. This function supports parameters of type number, string, and Boolean. Similar to booleans in JavaScript, any value except 0 or 'false' returns true.

The following example returns true:

"[bool(1)]"

The following example returns false:

"[bool(0)]"

The following example returns true:

"[bool(true)]"

The following example returns true:

"[bool('true')]"

decodeBase64

Decodes the parameter from a base-64 encoded string. This function supports parameters only of type string.

The following example returns "Contoso":

"[decodeBase64('Q29udG9zbw==')]"

decodeUriComponent

Decodes the parameter from a URL encoded string. This function supports parameters only of type string.

The following example returns "https://portal.azure.com/":

"[decodeUriComponent('https%3A%2F%2Fportal.azure.com%2F')]"

encodeBase64

Encodes the parameter to a base-64 encoded string. This function supports parameters only of type string.

The following example returns "Q29udG9zbw==":

"[encodeBase64('Contoso')]"

encodeUriComponent

Encodes the parameter to a URL encoded string. This function supports parameters only of type string.

The following example returns "https%3A%2F%2Fportal.azure.com%2F":

"[encodeUriComponent('https://portal.azure.com/')]"

float

Converts the parameter to a floating-point. This function supports parameters of type number and string.

The following example returns 1.0:

"[float('1.0')]"

The following example returns 2.9:

"[float(2.9)]"

int

Converts the parameter to an integer. This function supports parameters of type number and string.

The following example returns 1:

"[int('1')]"

The following example returns 2:

"[int(2.9)]"

parse

Converts the parameter to a native type. In other words, this function is the inverse of string(). This function supports parameters only of type string.

The following example returns 1:

"[parse('1')]"

The following example returns true:

"[parse('true')]"

The following example returns [1,2,3]:

"[parse('[1,2,3]')]"

The following example returns {"type":"webapp"}:

"[parse('{\"type\":\"webapp\"}')]"

string

Converts the parameter to a string. This function supports parameters of all JSON data types.

The following example returns "1":

"[string(1)]"

The following example returns "2.9":

"[string(2.9)]"

The following example returns "[1,2,3]":

"[string([1,2,3])]"

The following example returns "{"type":"webapp"}":

"[string({\"type\":\"webapp\"})]"
