send data to express.js in a for loop - mysql

Question

I need help with this, I really can't crack this one up.
I have this web site using Node.js to call mySQL queries and display them as tables, each in it's own page. To do so, I created 4 objects that include a name, a title and the query. when I have this code going four times (from queryPage[0] to queryPage[3]), It works great. But i want to put it into a for loop so I won't need 4 repetitions of the same lines, but then it doesn't work. the pages don't load... Any idea what is going on?
connection.query(queryPage[0].query, function(err, rows) {
var arr = [];
for (var i in rows) {
arr[i] = rows[i];
}
app.get('/' + queryPage[0].name, function(req, res) {
res.render('pages/' + queryPage[0].name, {
title: queryPage[0].title,
data: arr
});
});
});

I think you need something more like this
var queryPage = [ ... ];
// This route catches all request
app.get('/:name', function (req, res, next) {
// :name = req.params.name
var page;
for(var i = 0, l = queryPage.length; i < l; i++)
if(queryPage[i].name === req.params.name) {
page = queryPage[i];
break;
}
// Check the page exists
if(!page) return res.status(404).send('Not found');
// if(!page) return next();
connection.query(page.query, function(err, rows) {
res.render('pages/' + page.name , {
title: page.title,
data: rows
});
});
});
