I am trying to create onClick function that when user click into textarea it auto fully expand.
Here is my code base:
class DynamicWidthInput extends React.Component {
componentDidMount() {
const { id, value } = this.props;
resizable(document.getElementById(id), 16, value);
}
componentDidUpdate(prevProps) {
const { id, value } = this.props;
if (this.props.value !== prevProps.value) {
resizable(document.getElementById(id), 16, value);
}
}
render() {
const { id, placeholder, type, onChange, value, error, size } = this.props;
if (type === "textarea") {
return (
<div style={{ display: "inline-block", verticalAlign: "top" }}>
<textarea
className={`input dynamic-input dynamic-textarea ${size}`}
id={id}
onChange={onChange}
placeholder={placeholder}
value={value}
wrap="soft"
maxLength="1000"
{...this.props}
/>
{error && <p className="help is-danger">{error.message}</p>}
</div>
);
}
...
}
}
export default DynamicWidthInput;
Here is how I display textarea:
<DynamicWidthInput
id="addLoanClause"
value={addLoanClause}
type="textarea"
placeholder="1000 characters"
error={showErrors && getError("addLoanClause")}
onChange={e =>
handleDynamicStateChange(e, setAddLoanClause)
}
size={"xxl"}
rows="5"
/>{" "}
Here is how my project look like:
Expected fully display like this:
CodePudding user response:
I think you can use this style.
textarea {
transition: all .3s ease;
height: 100px;
}
textarea:focus {
height: 300px;
}
