示例1: _NPN_SetException
void _NPN_SetException (NPObject *o, NPString *message)
{
if (o->_class == NPScriptObjectClass) {
JavaScriptObject *obj = (JavaScriptObject *)o;
ExecState *exec = obj->executionContext->interpreter()->globalExec();
Interpreter::lock();
char *msg = (char *)malloc (message->UTF8Length + 1);
strncpy (msg, message->UTF8Characters, message->UTF8Length);
msg[message->UTF8Length] = 0;
Object err = Error::create(exec, GeneralError, msg);
free (msg);
exec->setException (err);
Interpreter::unlock();
}
}示例2: valueByEvaluatingJavaScriptFromString
JSValue* WebScriptCallFrame::valueByEvaluatingJavaScriptFromString(String script)
{
#if 0
ExecState* state = m_state;
JSGlobalObject* globObj = state->dynamicGlobalObject();
// find "eval"

JSValue* v = globObj->get(state, "eval");
if (v->isObject() && static_cast<JSObject*>(v)->implementsCall())
eval = static_cast<JSObject*>(v);
else
// no "eval" - fallback operates on global exec state

}
JSValue* savedException = state->exception();
state->clearException();

// evaluate
JSValue* scriptExecutionResult;
if (eval) {

} else

scriptExecutionResult = Interpreter::evaluate(state, UString(), 0, code.data(), code.size(), globObj).value();
if (state->hadException())

state->setException(savedException);
return scriptExecutionResult;
