jsdIStackFrame 编辑

Strict mode is on. Warnings reported as errors. Makes eval() use the last object on its 'obj' param's scope chain as the ECMA 'variables object'. Private data for this object is an nsISupports object. Attempting to alter this bit will result in an NS_ERROR_ILLEGAL_VALUE. OPT_* values above, OR'd together. Last version set on this context. Scripts typically select this with the "language" attribute. See the VERSION_* consts on jsdIDebuggerService. Unique tag among all valid jsdIContext objects, useful as a hash key. Private data for this context, if it is an nsISupports, |null| otherwise. Retrieve the underlying context wrapped by this jsdIContext. Top of the scope chain for this context. |true| if this context should be allowed to run scripts, |false| otherwise. This attribute is only valid for contexts which implement nsIScriptContext. Setting or getting this attribute on any other context will throw a NS_ERROR_NO_INTERFACE exception. Stack frame objects. These are only valid inside the jsdIExecutionHook which gave it to you. After you return from that handler the bottom frame, and any frame you found attached through it, are invalidated via the jsdIEphemeral interface. Once a jsdIStackFrame has been invalidated all method and property accesses will throw a NS_ERROR_NOT_AVAILABLE exception.
