Variables ¶
var TruthyTypes = []js.Type{ js.TypeUndefined, js.TypeNull, js.TypeBoolean, js.TypeNumber, js.TypeString, js.TypeSymbol, js.TypeFunction, js.TypeObject, }
TruthyTypes is a set (slice) of all js.Type which can be treated as a boolean.
Functions ¶
func AssertTypeEquals ¶
AssertTypeEquals returns nil if a given JavaScript value conforms to the given type.
func AssertTypeOneOf ¶
AssertTypeOneOf returns nil if a given JavaScript value conforms to one the given types
func GetBoolean ¶
GetBoolean retrieves a type-checked boolean from the global scope.
func GetFromScope ¶
GetFromScope retrieves an expression from the given scope.
func GetFunction ¶ added in v0.0.2
GetFunction retrieves a type-checked function from the global scope.
func GetTruthyBoolean ¶
GetTruthyBoolean retrieves a type-checked (truthy) boolean from the global scope.
func InvokeFunction ¶
InvokeFunction invokes a type-checked function from the global scope with the given arguments.
func JsCopyBytes ¶ added in v1.0.0
JsCopyBytes loads a Uint8Array or Uint8ClampedArray to a byte slice. It returns the number of bytes copied, which will be the minimum of the lengths of data and dst.
func JsToBytes ¶ added in v1.0.0
JsToBytes converts a JavaScript Uint8Array or Uint8ClampedArray to a Go byte slice.
func SetGlobalProperties ¶ added in v1.0.0
SetGlobalProperties sets propreties on the global object.
