Function expected
Either you attempted to invoke one of the Function prototype methods on an object that was not a Function
object, or you used an object in a function call context. For example, the following code produces this error because example is not a function.
var example = new Object(); // Create a new object called "example".
var x = example(); // Try and call example as if it were a function.
To correct this error
Only call Function prototype methods on
Function
objects.Ensure that you use the function call operator
()
to call functions only.
