send integers in FormData

Question

When I send an integer to the backend , I receive it as a string , I can't figure out why ?

var formdata = new FormData();

for (var i = 0; i < scope.user.values.length; i++) {
    formdata.append('values[]', scope.user.values[i]);
}

I receive values as string while they should be in integers

Relevant spec: Interface FormData: For the purposes of interaction with other algorithms, an entry's type is "string" if its value is a string and "file" otherwise. – Ruben

Answer 1

You actually cannot send integers, everything will be in string format and in key-value pairs when you use formData. Alternatively you can convert them to required datatype in backend.

What a silly feature... – Botanomancy

Answer 2

All values sent by HTML to the server-side are received as strings. You have to convert that data into integers in the backside, which shouldn’t be too difficult. If you specify which language your server-side is using maybe we could let you know how to convert string into integers in it.=, or ever better, you can look it up.

Try with solutions, It worked

In your controller update your variables as per your requirement

var a = []

$scope.b = [1,2,3,4]

for(var i =0 ; i < $scope.b.length; i++){ a.push(b[i]) }
