Message:

I am trying to delete by ID. But why don't show action=NaN in console.

Deleting..  form id="deletecategoryform" action="NaN" method="POST"

Here is my code

<script>

    function handleDelete(id){



       

        var form = document.getElementById('deletecategoryform')



        form.action = '/categories/' * id



        console.log('Deleting',form)



        $('#deleteModal').modal('show')

    }

   

</script>

My Answer:
The issue in your code is with the line `form.action = '/categories/' * id`. The `*` operator is used for multiplication in JavaScript, not for concatenating strings.

You should use the `+` operator to concatenate the strings like this:

javascript
form.action = '/categories/' + id;


This will properly set the action attribute of the form to the correct URL with the specific ID.
