Encodes a set of form elements as a query string.
|
|
|
|
- Use the `FormData` constructor to convert the HTML `form` to `FormData`.
|
|
- Use `Array.from()` to convert to an array, passing a map function as the second argument.
|
|
- Use `Array.prototype.map()` and `encodeURIComponent()` to encode each field's value.
|
|
- Use `Array.prototype.join()` with appropriate arguments 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
|
|
```
