I'm using the following code to delete a collection in my db:
Client:
$('.destroy').click(function() {
if(confirm("Are u sure?")) {
$.ajax({
type: 'DELETE',
url: '/destroy/' + dataId,
success: function(response) {
console.log('Success');
}
});
} else {
alert('Cancelled');
}
});
Server:
app.get('/destroy/:id', function(req, res) {
var id = req.param("id");
MyModel.remove({
_id: id
}, function(err){
if (err) {
console.log(err)
}
else {
console.log('Collection removed!');
}
});
});
Is working, if i click in the destroy button and reload the page, the collection will not be there, but the success callback function with the: [console.log('Success');]
is not running..
I need send a callback from the server to the client ir order to make the success function run???
How make the console.log('Success'); run??
Thanks.
The ajax call probably just times out, as it's never getting a response back from the server.
Send a response from the server
app.get('/destroy/:id', function(req, res) {
var id = req.param("id");
MyModel.remove({
_id: id
}, function(err){
if (err) {
res.end('error');
}
else {
res.end('success');
}
});
});
Then catch it
$.ajax({
type : 'DELETE',
url : '/destroy/' + dataId,
success : function(response) {
if ( response === 'error' ) {
alert('crap!');
} else if (response === 'success' ) {
alert('worked fine!');
}
}
});
This is a simplified example, you can return whatever you like, send statusCodes or whatever.
