示例1: valueByEvaluatingJavaScriptFromString
JSValue* WebScriptCallFrame::valueByEvaluatingJavaScriptFromString(String script)
{
#if 0
ExecState* state = m_state;
JSGlobalObject* globObj = state->dynamicGlobalObject();
// find "eval"
JSObject* eval = 0;
if (state->scopeNode()) { // "eval" won't work without context (i.e. at global scope)
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
state = globObj->globalExec();
}
JSValue* savedException = state->exception();
state->clearException();
UString code(script.utf8().data());
// evaluate
JSValue* scriptExecutionResult;
if (eval) {
