Covert form data to JSON string

Question

If I

Answer 1

Another way to do this, using plain js and form.elements as an argument to Array.reduce

var d = [].reduce.call(document.forms['test'].elements,(a,b)=>(a[b.name]=b.value,a),{});
var j = JSON.stringify(d, 0, 4);

console.log(j);

Using jQuery

var data = $('form :input').toArray().reduce( (a,b) => (a[b.name]=b.value,a),{})
var json = JSON.stringify(data,0,4);

console.log(data);
