Parameters

ParamTypeDetails
textstring

The text with markup to interpolate.

mustHaveExpression
(optional)

if set to true then the interpolation string must have embedded expression in order to return an interpolation function. Strings with no embedded expression will return null for the interpolation function.

trustedContext
(optional)
string

when provided, the returned function passes the interpolated result through $sce.getTrusted(interpolatedResult, trustedContext) before returning it. Refer to the $sce service that provides Strict Contextual Escaping for details.

  • context: an object against which any expressions embedded in the strings are evaluated against.
