is it possible to animate a strikethrough with React Spring? - reactjs

I'm new to React Spring and I initially tried this
const strikeProps = useSpring({
textDecoration: "line-through",
from: { textDecoration: "none" },
});
But it's not working. I think there should be a way simulate the CSS solution for this.

The problem here is, that the original CSS solution is uses pseudo element for emulating the strike trough. We can only add react-spring properties for normal html elements. So the most compact way is to create a separate strike through component for this problem. For example:
const StrikeTroughtText = ({ children, weight = 1 }) => {
const props = useSpring({
from: { width: "0%" },
to: { width: "100%" }
});
return (
<div style={{ position: "relative", display: "inline-block" }}>
{children}
<animated.div
style={{
position: "absolute",
top: "50%",
left: 0,
width: props.width,
height: `${weight}px`,
background: "black"
}}
/>
</div>
);
};
We basically animate the width of the absolutely positioned div containing a black line over the text.
You can use it like a div component:
<StrikeTroughtText>text</StrikeTroughtText>
For bigger font size the default 1 px line weight is not enough, so I added a weight property also.
Here is my example: https://codesandbox.io/s/react-strike-trought-text-component-with-react-spring-animation-86cfd?file=/src/App.js

Making signaturePad component take up full screen

Within one of my components a user can click a button that pulls up a signaturePad they can sign on. This is working, however, I'd like the signaturePad to take up the full screen, whereas now it appears between the footer and header. How can I accomplish this? I played around with using { flex: 1 } on the View of the SignaturePad, but this had no visible effect.
Here is the relevant code from the parent component. If a certain state is true, the signaturePad displays:
{this.state.signaturePanelIsVisible && (
<SignaturePanel
session={this.props?.session}
signaturePanelIsVisible={this.state.signaturePanelIsVisible}
/>
)}
And the signaturePad component code looks like this:
const SignaturePanel = (props) => {
const dispatch = useDispatch();
return (
<SignaturePanel
actionStyle={{
...styles.texts.mediumText,
color: styles.colors.primary,
textDecorationLine: 'underline',
}}
onCancel={async () => {
props.hideSignaturePanel();
}}
onSave={async (base64) => {
const base64Result = base64.base64DataUrl.substr(base64.base64DataUrl.indexOf(',') + 1);
dispatch(
await updateSignature({
...props.signature,
guid: props.session.guid,
value: base64Result,
lastUpdate: Date.serverTime(),
})
);
}}
/>
);
};
export default SignaturePanel;
And the styling applied looks like this:
container: {
width: '100%',
height: '100%',
zIndex: 98,
position: 'absolute',
backgroundColor: '#fff',
},
You'll need to add position: 'absolute' to the style of your modal. Setting the height and width to 100% as well sometimes works, depending on how your app is set up. This will either cover the screen with the component, or make the component appear under the header and overflow the bottom of the screen. To fix the latter issue, add top: -<height of header>. This way the component will move up and cover the header.
<Modal style={styles.modal}>
<View style={styles.signaturePad}>
</View>
</Modal>
modal: {
position: 'absolute',
height: '100%',
width: '100%',
top: -n, //(where n = height of your header)
}
signaturePad: {
height: '100%',
width: '100%',
}
Depending on how your project is set up, you may not need the top value. These are general settings that you should usually put on a modal component. It's considered best practice to have a modal cover the whole screen, then add the component you want to display as a subcomponent.

How to make react-modal scrollable?

Im trying to make my modal (react-modal node package) scrollable (There is an img inside)
here is my code:
content: {
position: 'absolute',
backgroundColor: '#FFF',
padding: '15px',
zIndex: '1000',
width: '90%',
borderRadius: '.5em',
},
overlay: {
position: 'fixed',
display: 'flex',
justifyContent: 'center',
top: '0',
left: '0',
width: '100%',
height: '100%',
backgroundColor: 'rgba(0,0,0, .8)',
zIndex: '1000',
overflowY: 'auto',
},
}
Modal.setAppElement('#__next')
export const langContext = React.createContext()
export default function Home() {
const [isEn, setIsEn] = useState(true)
const [modalIsOpen, setIsOpen] = useState(false)
const { width } = useWindowDimensions()
function openModal() {
setIsOpen(true)
}
function closeModal() {
setIsOpen(false)
}
function updateLang() {
setIsEn((isEn) => !isEn)
}
return (
<langContext.Provider value={{ isEn, updateLang }}>
<div id="modal" className="overflow-hidden relative">
<Header />
<Modal
isOpen={modalIsOpen}
onRequestClose={closeModal}
style={customStyles}>
<div className="relative m-h-[1000px] h-full w-full overflow-y-scroll">
{isEn ? (
<Image
layout="fill"
objectFit={width >= 750 ? 'fill' : ' cover'}
quality={100}
src={
width >= 750 ? '/assets/menu-en.png' : '/assets/Menu_en_m.png'
}
alt="Menu"
/>
) : (
<Image
layout="fill"
objectFit={width >= 750 ? 'fill' : ' cover'}
quality={100}
src={
width >= 750 ? '/assets/menu-he.png' : '/assets/Menu_he_m.png'
}
alt="Menu"
/>
)}
</div>
</Modal>
</div>
</langContext.Provider>
)
}
Any ideas on how can I do it? (I'm trying to play with the overflow and position element but I can't find the proper solution
The scrolling suppose to happen on Mobile and the Image dimensions are: 550*1550 (I can resize it if necessary)
Right now the image is cut
Thanks for the helpers!
I think your modal is good in terms of vertical scrolling, but the problem has may come from this line
objectFit={width >= 750 ? 'fill' : 'cover'}
Your mobile dimension is 500*1550 which means the image will take object-fit:cover;
You can check object-fit:cover; definition here
The image keeps its aspect ratio and fills the given dimension. The image will be clipped to fit
If you already check the dimension to load the device-respective image, you can remove the condition to check for cover.
object-fit:fill is sufficient for your case
The change can be
objectFit="fill"
Another potential problem I can see here that you have layout="fill" for that image which will make it absolute. The image container has relative which restricts the original size of your image.
To fix it, you may need to remove relative from the image container too.

How do I add a hover selector to a style object?

I created a style object in react that I will pass through a style prop:
const iconStyle = {
color: "#464545",
fontSize: "24px",
margin: "20px",
transitionProperty: "color",
transitionDuration: "1s",
}
Any idea on how I could add a hover selector inside of it, because I've looked around and I still have no clue.
probably this pseudo selector will help.
const iconStyle = {
color: "#464545",
fontSize: "24px",
margin: "20px",
transitionProperty: "color",
transitionDuration: "1s",
"&:hover": {
background: "#efefef"
},
}
In React.js there is no such way hover.
You can accomplish your goal with these two states.
onMouseEnter={() => this.setState({hover: true})}
onMouseLeave={() => this.setState({hover: false})}
And you can use "hover" state(for example) to specify styles like
style = this.state.hover ? style1 : style2
Hope this helps you to understand!

How can I disable multiline for autocomplete material-ui demo?

Country select of
autocomplete demo at material-ui
uses react-select and material-ui controls,
shows multiline text, select control changes it's dimensions when country doesn't fit in one line.
I see this behaviour at CodeSandbox when I decrease width of web browser.
How can I modify demo so that country will always fit in one line,
select control will not change it's dimensions?
TextField has props multiline, rows and rowsMax props that can be changed.
If that isn't what you need then you could add the following css to the text in the TextField so the text does not wrap:
overflow: hidden;
white-space: nowrap;
I managed this by mixing a few different things:
First create a class like so:
const useStyles = makeStyles((theme: Theme) =>
createStyles({
closed: {
flexWrap: "nowrap",
overflowX: "hidden",
},
// Add a linear gradient behind the buttons and over the Chips (if applies)
endAdornment: {
background:
"linear-gradient(90deg, rgba(255,255,255,0) 0%, rgba(255,255,255,.6) 22%, rgba(255,255,255,1) 60%)",
bottom: 0,
display: "flex",
alignItems: "center",
right: "0 !important",
paddingRight: 9,
paddingLeft: theme.spacing(2),
top: 0,
},
})
);
Then in your static function add this :
const onOpenChange = (open: boolean | null) => {
setIsOpen(open);
};
const inputStyle = clsx({
[classes.closed]: !isOpen, //only when isOpen === false
});
Finally on the Autocomplete component itself use:
classes={{ inputRoot: inputStyle, endAdornment: classes.endAdornment }}
onOpen={() => onOpenChange(true)}
onClose={() => onOpenChange(false)}
If you are wondering how to make each option be displayed in just one line with ellipsis, you can do the follow:
<Autocomplete
...
getOptionLabel={(option: any) => `${option.label} (${option.code})`}
renderOption={(option) => (
<React.Fragment>
<div style={{ textOverflow: 'ellipsis', overflow: "hidden", whiteSpace: "nowrap" }}>
{option.label} ({option.code})
</div>
</React.Fragment>
)}
...
/>
For the Country Demo example, you can check what I did here: https://codesandbox.io/s/autocomplete-with-ellipsis-i8hnw

How to do CSS :hover function in JSX ?

Hi and thanks for the great job here. I am using react.js for my project to build my components and I feel a little bit stuck in my project right now. I am trying to style a button with a hover function and I don't know how to apply this to react.
Here is the code :
let button = {
backgroundColor: colorPalette.white,
border: "1px solid rgb(12,106,145)",
color: colorPalette.brandCol1,
textAlign: 'center',
textDecoration: 'none',
fontSize : 'inherit',
fontWeight : 600,
padding : "5px 8px 5px 8px"
}
and I would like to add a hover style to it just like we do in css with
button:hover {
style here.......
}
What is the correct syntax ?
You can use:
const styles = {
myStyleClassName: {
padding: '16px 0px 16px 0px',
'& a': {
textDecoration: 'none',
color: '#0000ee',
},
'& a:hover': {
textDecoration: 'underline',
},
},
myButtonClass: {
'&:hover': {
textDecoration: 'underline',
},
},
};
....
render() {
<span className={myStyleClassName}><a tag><button><someDomObjct></span>
<button className={myButtonClass}>my label</button>
}
See: http://cssinjs.org/jss-nested/?v=v6.0.1
The repo isn't necessary for everything, the above should work out of the box.
You can use onMouseEnter onMouseLeave to adjust the state of the component
<button
onMouseEnter={() => setButtonHovered(true)}
onMouseLeave={() => setButtonHovered(false)}
className={buttonIsHovered ? 'hover' : null}
/>
see here for more info
or just use a css class?
import './style.css'
<button className="Button"/>
.Button:hover {
...
}
Using react to manage state for a hover animation is way overkill. You shouldn't need to use javascript for a simple CSS hover...You're in the browser, use the right tool for the right job, right?
So here I'll show a couple different ways to approach the same goal:
In my component I import glamor and my styles file:
import { style } from 'glamor';
import styles from '../styles';
And in my styles file, I have something like this:
import { style } from 'glamor';
const styles = {
redHoverbutton: style({
backgroundColor: "#aaaaaa",
fontSize: "1.1rem",
transition: "all ease .5s",
":hover": {
backgroundColor: "#ff0000",
color: "#ffffff"
}
})
};
export default styles;
And this makes the hover functionality work via css, like this:
<div {...styles.redHoverbutton}></div>
This is a css driven hover effect (with transition if you noticed) but this isn't inline css. None the less, your style can be crafted in the same file, like this:
let theStyle = style({ backgroundColor: "#aaaaaa",transition: "all ease .5s", ":hover": { cursor: "pointer", backgroundColor: "#ffff9b", color: "#fd0808" } });
return (<div {...theStyle}>Hover me!</div>);
Now, how to get the style and the spread operator onto the same line and inside of the JSX element?
<div {...style({ backgroundColor: "#aaaaaa", height: "30px", width: "100%", padding: "6px", fontsize: "16px", transition: "all ease .5s", ":hover": { cursor: "pointer", backgroundColor: "#ffff9b", color: "#fd0808" } })}>Hover Me!</div>
It may not be perfect but it works well and accomplished the same thing as a true inline style and in a similar manner.
