[edit] Syntax

typedef enum JSExecPart { JSEXEC_PROLOG, JSEXEC_MAIN } JSExecPart;

JSBool JS_ExecuteScriptPart(
    JSContext *cx, JSObject *obj, JSScript *script,
    JSExecPart part, jsval *rval);

Name	Type	Description
cx	JSContext *	The context in which to execute the script. Requires request. (In a JS_THREADSAFE build, the caller must be in a request on this JSContext.)
obj	JSObject *	The scope in which to execute the script. This parameter is documented in detail at JS_ExecuteScript.
script	JSScript *	The compiled script to execute.
part	JSExecPart	The part of script to execute.
rval	jsval *	Out parameter. On success, *rval receives the value from the last executed expression statement in the script.

[edit] Description

JS_ExecuteScriptPart executes part of a previously compiled script, script. The part parameter must be either JSEXEC_PROLOG to execute the script prolog or JSEXEC_MAIN to execute the main section of the script.

If the script executes successfully, JS_ExecuteScriptPart stores the value of the last-executed expression statement in the script in *rval and returns JS_TRUE. Otherwise it returns JS_FALSE, and the value left in *rval is undefined.

To execute both parts of a script, use JS_ExecuteScript instead.
