ECMA Section: 10.2.2 Eval Code
|
|
Description:
|
|
|
|
When control enters an execution context for eval code, the previous
|
|
active execution context, referred to as the calling context, is used to
|
|
determine the scope chain, the variable object, and the this value. If
|
|
there is no calling context, then initializing the scope chain, variable
|
|
instantiation, and determination of the this value are performed just as
|
|
for global code.
|
|
|
|
The scope chain is initialized to contain the same objects, in the same
|
|
order, as the calling context's scope chain. This includes objects added
|
|
to the calling context's scope chain by WithStatement.
|
|
|
|
Variable instantiation is performed using the calling context's variable
|
|
object and using empty property attributes.
|
|
|
|
The this value is the same as the this value of the calling context.
