serializeForm
Encode a set of form elements as a query string.
Use the FormData
constructor to convert the HTML form
to FormData
, Array.from()
to convert to an array, passing a map function as the second argument.
Use Array.prototype.map()
and window.encodeURIComponent()
to encode each field's value.
Use Array.prototype.join()
with appropriate arguments to produce an appropriate query string.
const serializeForm = (form) =>
Array.from(new FormData(form), (field) =>
field.map(encodeURIComponent).join("=")
).join("&");
serializeForm(document.querySelector("#form")); // email=test%40email.com&name=Test%20Name
