Hey guys,
I'm not entirely sure this is the right forum for this, but I'm trying
to figure out the best way to do this and I am using SQLite. I am
cusing it for an Android app i am making. I'm using jQuery Mobile and
PhoneGap, so we're dealing with JavaScript. I have created two tables
in SQlite, "Areas" and "Restaurants". I am essentially building an app
that displays restaurants in certain areas. What I am trying to do is
create a nested list which would display the Areas and within the
areas the Restaurants. Like so:
<ul>
<li>Area 1
<ul>
<li>Restaurant 1</li>
<li>Restaurant 2</li>
</ul>
</li>
<li>Area 2
<ul>
<li>Restaurant 3</li>
<li>Restaurant 4</li>
</ul>
</li>
</ul>
So I am using JavaScript to query the Areas and loop through them and
then query the Restaurants and loop through those to create my list,
but it is not working right. When I output the list, I am only getting
the areas back and not the restaurants. I'm sure I'm not doing this
right and there may be a way better way of doing this. Below is what
I'm using.
db.transaction(function(tx) {
tx.executeSql('SELECT * FROM Areas;', [],
function(transaction, areaResult) {
var theHtml = '';
if (areaResult != null &&
areaResult.rows != null) {
for (var i = 0; i <
areaResult.rows.length; i++) {
var areaRow =
areaResult.rows.item(i);
theHtml += '<li>' +
areaRow.AreaName;
tx.executeSql('SELECT *
FROM Restaurants WHERE AreaID = ?;',
[areaRow.AreaID],
function(transaction, restaurantsResult) {
theHtml = '<ul>';
for (var i2 = 0; i2 < restaurantsResult.rows.length; i2++)
{
var restaurantsRow = restaurantsResult.rows.item(i2);
theHtml += '<li>' + restaurantsRow.RestaurantName + '</
li>';
};
theHtml += '</ul>';
}
);
theHtml += '</li>';
}
}
$('#areas').html(theHtml);
$('#areas').listview("refresh");
});
});
