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 |

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 . |

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 |

rval |
jsval * |
Out parameter. On success, *rval receives the value from the last executed expression statement in the script. |
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.
