Easy way to get Form values in React
//Given a form,
<form onSubmit={props.submitLaunch}>
<label htmlFor="launch-day">Launch Date</label>
<input type="date" id="launch-day" name="launch-day" min={today} max="2040-12-31" defaultValue={today} />
<label htmlFor="mission-name">Mission Name</label>
<input type="text" id="mission-name" name="mission-name" />
<label htmlFor="rocket-name">Rocket Type</label>
<input type="text" id="rocket-name" name="rocket-name" defaultValue="Explorer IS1" />
<label htmlFor="planets-selector">Destination Exoplanet</label>
<select id="planets-selector" name="planets-selector">
{selectorBody}
</select>
</form>
//add in a submitLaunch props which is a function that processes the formData
//the submitLaunch function would contain the following
const submitLaunch = useCallback(async (e) => {
e.preventDefault();
const data = new FormData(e.target);
const launchDate = new Date(data.get("launch-day"));
const mission = data.get("mission-name");
const rocket = data.get("rocket-name");
const target = data.get("planets-selector");
const response = await httpSubmitLaunch({
launchDate,
mission,
rocket,
target,
});
//useCallback which is used to return a memoized callback
//data.get is then used to extract the value of the form with their respective IDs
