[Solved] How to pass data from Qt application to Javascript function?

[zither]

Dear all friends,

Qt Application

@ QString from;
QFile file( ":/test.js");
if ( !file.open(QIODevice::ReadOnly | QIODevice::Text) )
{
from = "Hello!";
QString functions = file.readAll();
QWebFrame* frame = ui->webView->page()->mainFrame();
frame->evaluateJavaScript( functions );

QString script = QString("myFunction(%1);").arg( from );
frame->evaluateJavaScript(script);
}

@

Is there somethings wrong with my function call?

Thanks

Here is test.js

@ function myFunction (from)

{
 
alert("This is testing... ");
alert(from);
 
}@

It would most likely be simpler to just stick an QObject into the JS context via "QWebFrame::addToJavaScriptWindowObject(...)":http://doc.qt.nokia.com/4.7-snapshot/qwebframe.html#addToJavaScriptWindowObject and interact over that one.

This works better when you have the JS under your control:-)
