[SOLVED] Question about addToJavaScriptWindowObject

dolevo

Hi all,

I have created a class whose function is going to be called from inside of a javascript. Here is my class:

@class web1: public QObject
{
public:
web1() {};

void mpSetValue(int value) { qDebug() << value;}

};@

I also created a slot which is going to be fired when mainFrame emits javaScriptWindowObjectCleared like below:
@ connect(webView->page()->mainFrame(), SIGNAL(javaScriptWindowObjectCleared()),
this, SLOT(populateJavaScriptWindowObject()));@

and here is my slot:

@void engine2dehands::populateJavaScriptWindowObject(void)
{
qDebug() << "---==>> populateJavaScriptWindowObject";
webView->page()->mainFrame()->addToJavaScriptWindowObject("webb", wb);
}@

Here is the code where I run my [removed]

@ QWebElement aAfdeling = aElement.findFirst("select[id='dropdownlist']");

QString jsCode = QString("var exists = false;"
                 "for(var i = 0, opts = document.getElementById('dropdownlist').options; i < opts.length; ++i)"
                 "   if( opts[i].value === '%1' )"
                 "   {"
                 "        alert&#40;\"kids found in dropdown menu\"&#41;;"
                 "    webb.mpSetValue(i&#41;;"
                 "    break;"
                 " }").arg("kids");

qDebug() << jsCode;
aElement.evaluateJavaScript(jsCode);@

There is a dropdown menu in the target webpage and above function finds the order of the item in this dropdown list. The javascript function work perfect since I get "kids found in dropdown menu" message. right after that message, I should get a debug message with the order, but I get nothing. populateJavaScriptWindowObject slot is also called and I see the debug log in there as well. Could anyone tell me how I can get the value out? Where am I doing wrong?

Hi,

You must declare mpSetValue as a slot.

Excellent!!! It works now.
