I have this reusable component where I would like to pass a value through that if true: a button is returned and if the value is false: the button doesn't render. I can't figure out how to do this using reusable components. The boolean variable I want to use is displayButton where if it is true, then the button is rendered and if it is false then the button is not rendered.
const Test = ({ name, value, onClick, purchased, displayButton }) => {
return (
<div class="cardData">
<h5>{name}</h5>
<p>Cost: {value}</p>
//if display button = true, display this button, if false, button is not displayed
<button
type="button"
onClick={onClick}
class="btn btn-primary"
value={value}
name={name}
>
Purchase
</button>
<h4>{purchased}</h4>
</div>
);
};
export default Test;
Any help would very appreciated!
const Test = ({ name, value, onClick, purchased, displayButton }) => {
return (
<div class="cardData">
<h5>{name}</h5>
<p>Cost: {value}</p>
{displayButton &&
<button
type="button"
onClick={onClick}
class="btn btn-primary"
value={value}
name={name}
>
Purchase
</button>
}
<h4>{purchased}</h4>
</div>
);
};
export default Test;
if displayButton
has the value of true
it will render the button otherwise not
This will work.
const Test = ({ name, value, onClick, purchased, displayButton }) => {
return (
<div class="cardData">
<h5>{name}</h5>
<p>Cost: {value}</p>
{ displayButton &&
<button
type="button"
onClick={onClick}
class="btn btn-primary"
value={value}
name={name}
>
Purchase
</button>
}
<h4>{purchased}</h4>
</div>
);
};
export default Test;
You can create a ShowHide
component which can be utilized for conditional-rendering instead of having logical operators in every JSX
where you need to conditionally render.
// create a ShowHide component const ShowHide = ({show,children} ) => show && children // your Test component with the button wrapped in ShowHide const Test = ({ name, value, onClick, purchased, displayButton }) => { return ( <div class="cardData card col-6 m-3"> <h5>{name}</h5> <p>Cost: {value}</p> <ShowHide show={displayButton}> <button type="button" onClick={onClick} class="btn btn-primary" value={value} name={name} > Purchase </button> </ShowHide> <h4>{purchased}</h4> </div> ); }; const root = document.getElementById('root'); ReactDOM.render( <Test name="My Card" value="250,000" onClick={() => alert('clicked')} purchased="Yes!" displayButton={false} />, root )
