Variable Pattern

The variable syntax begins with a colon, including :currentData, :formData, :response, :context, :params, :searchParams. In the component's property list, whether Variable Pattern is supported` is checked.

:currentData​

:currentData represents the field of the current data. like

:currentData.id represents the id of the current data. If the use place is not in the table row, data component Data container, List component, etc., then :currentData is equal to :formData.

Since :currentData is very commonly used, you can use abbreviation syntax, you can omit :currentData and write :id directly.

Translation (no colon parsing)​

Normally, in properties that support Variable Pattern, all strings starting with : will be parsed as variables that need to be parsed according to the following.

For example: /abc/def/:name/xyz. If the value of the name field is 123, then the string will be parsed as /abc/def/123/xyz.

When there is a : string that contains : that does not require parsing, you can use the translation symbol \ to translate this :.

For example: linking to a fixed port /abc/def/xyz\:9092 will finally output the link /abc/def/xyz:9092, and 9092 will not be parsed as a variable.
