JS_ExecuteScriptPart

Obsolete since JavaScript 1.9.3
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

JS_ExecuteScriptPart has been removed in bug 555104. Use JS_ExecuteScript instead.

Executes a part of a compiled script.

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.

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.
