When clicking Reset, form should go back to initial values, but the Select element goes back to first option available, have used the same method for all other form elements, and they update correctly.
Have made a Codesandbox example of the problem : https://codesandbox.io/s/lively-snowflake-tf5te
function App() {
// Data for select dropdown box - selected is Lime
const SelectData = ["Grapefruit", "Lime", "Coconut", "Mango"];
// Selected Value
const selectedValue = "Lime";
// Set state
const [selectBox, setSelectBox] = useState(selectedValue);
// Submit finction
const handleSubmit = e => {
e.preventDefault();
alert(`Select Selection #1: ${selectBox}`);
};
// Reset function
const handleReset = () => {
setSelectBox(selectedValue);
};
return (
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>
When 'Reset' is clicked first options is selected
<br />
and not the state value.
</h2>
<form onSubmit={handleSubmit}>
<Select
label="Select Fruit"
value={selectBox}
handleChange={e => setSelectBox(e.target.value)}
data={SelectData}
/>
<br />
<br />
<input type="submit" value="Submit" />
<input type="reset" value="Reset" onClick={handleReset} />
</form>
<br />
Selectbox state value: {selectBox}
<br />
</div>
);
}
Expected result, after Resetting Form, is that then Select element value is "Lime", but it is "Grapefruit".
I changed the value
to defaultValue
in your DropDown.js
file and it worked like charm. Check the sandbox
<select defaultValue={value} onChange={handleChange}>
{data.map(item => (
<option key={item} value={item}>
{item}
</option>
))}
</select>
