### 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 argumens to produce an appropriate query string.
|
|
|
|
```js
|
|
const serializeForm = form =>
|
|
Array.from(new FormData(form), field => field.map(encodeURIComponent).join('=')).join('&');
|
|
```
|
|
|
|
```js
|
|
serializeForm(document.querySelector('#form')); // email=test%40email.com&name=Test%20Name
|
|
```
