you can call as the following:
bool returnFlag = false;
WebCore::Frame* pMainFrame = GetFrame();//Note 10/19/10 - abaldeva - We need to
investigate if we should get the focus Or MainFrame here.
if(pMainFrame)
{
WebCore::ScriptController* pProxy = pMainFrame->script();
if(pProxy)
{
const WebCore::String sFileName;
const int baseLine = 1;
const WebCore::String sScriptSource(pScriptSource, length);
KJS::JSValue* pValue = pProxy->evaluate(sFileName, baseLine, sScriptSource);
if(pValue)
{
if(pReturnValue)
{
// we need the exec only because JSArray::get requires the
exec state. This could potentially be removed.
ExecState* exec =
pProxy->windowShell()->window()->globalExec();
TranslateJavaScriptValue(pValue, pReturnValue, exec);
}
// 7/27/10 CSidhall So this is a small API change, we now
return true if a non zero pValue was found versus previously where
// we only returned true if pValue was non zero and a
pReturnValue was set by the user. This was suggested by Chin Yee Cheng.
// So any return with a non NULL pValue is a success. (It is
unclear if there could be some special
// exceptions to this in case of with "Break" or "Continue"
internal JS completion codes but we consider those as fails for now).
returnFlag = true;
}
else
{
// No valid return so leave the returnValue to undefined
}
// 5/12/10 CSidhall - Changed this to just flag the update instead
of doing a full layout update as EvaluateJavascript might be called x times in
a same frame.
// We could consider only updating the layout in case only of a pValue
return
WebCore::FrameView* const pMainFrameView = GetFrameView();
if(pMainFrameView)
pMainFrameView->setNeedsLayout();
}
}
