Installation
npm i @uiw/react-iframe
Basic Usage
import React from 'react';
import IFrame from '@uiw/react-iframe';
export default function Demo() {
return (
<IFrame>
<h1>Hello World!</h1>
</IFrame>
);
}
head
The head
prop is a dom node that gets inserted before the children of the frame.
import React from 'react';
import IFrame from '@uiw/react-iframe';
const head = (
<style>{`body { background: red; }`}</style>
);
export default function Demo() {
return (
<IFrame head={head}>
<h1>Hello World!</h1>
</IFrame>
);
}
initialContent
The initialContent
props is the initial html injected into frame. It is only injected once, but allows you to insert any html into the frame (e.g. a <head>
tag, <script>
tags, etc). Note that it does not update if you change the prop.
Defaults to <!DOCTYPE html><html><head></head><body></body></html>
import React from 'react';
import IFrame from '@uiw/react-iframe';
const initialContent = '<!DOCTYPE html><html><head><title>React IFrame</title><meta name="keywords" content="react,iframe,component,development" /></head><body></body></html>';
export default function Demo() {
return (
<IFrame initialContent={initialContent}>
<div style={{ fontSize: 32, color: 'red' }}>Hello World!</div>
</IFrame>
);
}
mountTarget
The mountTarget
attribute is a css selector (#target
/.target
) that specifies the child within the initial content of the iframe to be mounted.
import React from 'react';
import IFrame from '@uiw/react-iframe';
const initialContent = '<!DOCTYPE html><html><head></head><body><h1>i wont be changed</h1><div id="mountHere"></div></body></html>';
export default function Demo() {
return (
<IFrame initialContent={initialContent} mountTarget="#mountHere">
<div style={{ fontSize: 32, color: 'red' }}>Hello World!</div>
</IFrame>
);
}
ref
The ref prop provides a way to access inner <iframe>
DOM node.
import React, { useEffect, useState, Fragment } from 'react';
import IFrame from '@uiw/react-iframe';
export default function Demo() {
const [iframeRef, setIframeRef] = useState();
const [count, setCount] = useState(0);
useEffect(() => {
if (iframeRef) {
iframeRef.focus();
}
}, [iframeRef]);
const click = () => setCount(count + 1);
return (
<Fragment>
<button onClick={click} style={{ display: 'flex' }}>Click</button>
<IFrame ref={(node) => node && setIframeRef(node)}>
<div>Hello World!</div>
<div style={{ fontSize: 32, color: 'red' }}>{count}</div>
</IFrame>
</Fragment>
);
}
src
Open a URL in an <iframe>
.
import React, { useEffect, useState, Fragment } from 'react';
import IFrame from '@uiw/react-iframe';
export default function Demo() {
return (
<IFrame src="https://wangchujiang.com/" style={{ width: '100%', height: 320 }} />
);
}
Accessing the iframe's window
and document
The iframe's window
and document
may be accessed via the FrameContext.Consumer
or the useFrame hook.
import React, { useEffect, useState, Fragment } from 'react';
import IFrame, { FrameContext } from '@uiw/react-iframe';
export default function Demo() {
return (
<IFrame>
<FrameContext.Consumer>
{({ document, window }) => {
return (
<div>
<div>Hello World!</div>
</div>
)
}}
</FrameContext.Consumer>
</IFrame>
);
}
The example with useFrame
hook:
import React, { useEffect, useState, Fragment } from 'react';
import IFrame, { useFrame } from '@uiw/react-iframe';
const InnerComponent = () => {
const { document, window } = useFrame();
return (
<div>
<div>Hello World!</div>
</div>
);
};
export default function Demo() {
return (
<IFrame>
<InnerComponent />
</IFrame>
);
}
Event
import React, { useEffect, useState, Fragment } from 'react';
import IFrame, { useFrame } from '@uiw/react-iframe';
const InnerComponent = () => {
const { document, window } = useFrame();
return (
<div>
<div>Hello World!</div>
</div>
);
};
export default function Demo() {
const onLoad = (evn) => {
console.log("iframe loaded successfully!", evn)
}
return (
<IFrame onLoad={onLoad}>
<InnerComponent />
</IFrame>
);
}
Props
export interface IFrameProps extends React.HTMLAttributes<HTMLIFrameElement> {
head?: React.ReactNode;
initialContent?: string;
mountTarget?: string;
}
declare const IFrame: import("react").ForwardRefExoticComponent<IFrameProps & import("react").RefAttributes<HTMLIFrameElement>>;
export default IFrame;
