I want to reuse my jsx element in multiple places.
const value= <div>some text<Link href="abc.com">text</Link></div>
and I want to call value in multiple places.
I tried adding ' ' for the div but not getting element properly. It is returing as string. Can someone explain me the correct syntax to render jsx element to JavaScript variable?
I want to reuse my jsx element in multiple places.
You can't. It can only be used in one place. It would appear that you can, I stand corrected by Mosè Raguzzini , this works just fine::
const value= <div>some text<Link href="http://example.com">text</Link></div>;
ReactDOM.render(
<div>
{value}
{value}
{value}
</div>,
document.getElementById("root")
);
Live Example:
const value= <div>some text<a href="http://example.com">text</a></div>; ReactDOM.render( <div> {value} {value} {value} </div>, document.getElementById("root") );
<div id="root"></div> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.9.0/umd/react.production.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.9.0/umd/react-dom.production.min.js"></script>
Another approach is to have a function that creates identical copies of it:
const getValue = () => <div>some text<Link href="abc.com">text</Link></div>;
Then when you want one, use getValue()
to get it.
Or even give that a capital letter so it's a functional component:
const Value = () => <div>some text<Link href="abc.com">text</Link></div>;
Live Example (of both):
const getValue = () => <div>some text<a href="http://example.com">text</a></div>; const Value = () => <div>some text<a href="http://example.com">text</a></div>; ReactDOM.render( <div> {getValue()} {getValue()} <Value /> <Value /> </div>, document.getElementById("root") );
<div id="root"></div> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.9.0/umd/react.production.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.9.0/umd/react-dom.production.min.js"></script>
how to store jsx element to javascript variable
You can't reuse a React element the way you've shown, but there's nothing wrong with:
const value= <div>some text<Link href="abc.com">text</Link></div>
(other than relying on ASI at the end, because there's no ;
). That works just fine. But it doesn't make it reusable.
Here's an example doing that:
const value= <div>some text<a href="http://example.com">text</a></div>; ReactDOM.render( <div> {value} </div>, document.getElementById("root") );
<div id="root"></div> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.9.0/umd/react.production.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.9.0/umd/react-dom.production.min.js"></script>
You could create a stateless component to reuse said component:
import React from "react"
export const MyComponent = () => (
<div>
some text <Link href="abc.com">text</Link>
</div>
);
I assume that you want to send dynamic content to the Links, so made href as ref:)
function MyFunction(){
const Value = ({ href }) => <div>some text<Link href={ href }>text</Link></div>;
return (
<div>
<p> div with value and more </p>
<Value href={"a.com"} />
<Value href={"b.com"} />
<Value href={"c.com"} />
</div>
)
}
