In perl hashes are unordered. But if they were, you case wouldn't be
working too(because in js objects are unordered too, unlike ES6 "Set").
But you can use the result in your case as array without modification:
#server
$data = [1,2,3];
return $self->render(json => { data => $data }); # NOT (json => $data)!
// browser
res.json.data.forEach(el => console.log(el));
Hello guys, I'm new to the group and to Mojolicious,
I was curious to try it out earlier on and I noticed that when
retrieving data from the db and parsing it to json, the data can
assume different patterns and the elements are not always displayed in
the browser with the same sequence... The key->value relationship is
always correct, just the order of data, data1,data2 changes. Is that
normal?
How can that be solved?
The code I use is the following:
|
my$SQL ="SELECT * FROM Persons WHERE PersonID=$id";
my$cursor =$self->db->prepare($SQL);
$cursor->execute;
my@data=$cursor->fetchrow();
$cursor->finish();
$self->db_disconnect();
return$self->render(json =>{data
=>$data[0],data1=>$data[1],data2=>$data[2]});
|
Thank you.
