I have a POST form in html with this structure:
name1 email1 address1
on a button press a new div with the exact same fields appears with a number higher
This data gets posted to an express function where a foreach loop is supposed to fetch the data.
The problem I am having is incrementing the req.body.name in the foreach
The following code is the closest I have gotten, however I always get a "NaN" error
app.post('/submit', function(req, res) {
for (var i = 1; i <= req.body.numberOfItems; i++) {
console.log(req.body.name += i);
}}
In your code you are incrementing the req.body.name value.
You should change the key only
app.post('/submit', function(req, res) {
for (var i = 1; i <= req.body.numberOfItems; i++) {
console.log(req.body["name"+i]);
}}
Thank you for that, worked like a charm. As I am not using an array I thought I could not change the key.
@Julius this is not an array. As you are using dynamic object keys (name1, name2, name3), you should use brackets instead of dot to specify the key on the
req.bodyobject
