Reference Error: google is not defined

[karthick]

Hi All,
I am trying to execute javascript through Qt script.
My javascript contains code for google maps API.
when i ran it through Qt script, it gives an Error like "Reference
Error: google is not defined".

I think the problem is the
<script type="text/javascript" src="http://maps.google.com/maps/api/js?
sensor=false">
</script>
line from the html file. If I use the <> brackets, the java script
engine won't compile it, and if I omit the line, the program gets the
"google not found" error...

Please anyone help me how to call URL inside script tag in javascript
which is been executed by Qt script?

NOTE:
Here, I have included JS and Qt script file.
JS file:
function calcRoute() {
var directionsService = new google.maps.DirectionsService(); //
getting error here."google not defined"
var start = "chennai";
var end = "bangalore";
var request = {
origin:start,
destination:end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(resp, status) {
if (status == google.maps.DirectionsStatus.OK) {
return resp;
}

});
}

QtScript file:
#include <QApplication>
#include <QtScript>
#include <QScriptEngine>

int main(int argc, char **argv)
{
QApplication app(argc, argv);
QScriptEngine engine;
QScriptValue global = engine.globalObject();

QString fileName1 = "direction.js";
QFile scriptFile1(fileName1);
if(!scriptFile1.open(QIODevice::ReadOnly))
{
qDebug() << "error";
}
QTextStream stream1(&scriptFile1);
QString contents1 = stream1.readAll();
scriptFile1.close();
QScriptValue result1 = engine.evaluate(contents1, fileName1);
if(engine.hasUncaughtException()) {
int line = engine.uncaughtExceptionLineNumber();
qDebug() << "uncaught exception at line" << line << ":" <<
result1.toString();
}
QScriptValue val1 = global.property("calcRoute");
QScriptValueList args1;
QScriptValue final_res1 = val1.call(QScriptValue(), args1); //
calling JS function calcRoute with no args
qDebug() << "The result is: " << final_res1.toString();
return app.exec();
}

For questions about how to use Qt, try here
http://www.qtcentre.org/forum.php

The maps javascript is normally loaded with <script> tag in a webpage

@Rossko: does it mean it is loaded in webpage only?
                  is it possible to load maps javascript API on non web browser environment?

It may be possible, but is against the terms of use.
