Has any one got a function component of Like Button,instead of class component, working in a straight HTML page ?
I don't think there's a way to get functional components to work. I used to use functional components until I started using React without JSX; I've totally switched over to using the class components.
thanks for support while the tutorial of react cn was out-date
Hi all.
@spicecoder yes here is it for function component:
'use strict';
const e = React.createElement;
function LikeButton(props) {
const [liked,setLiked] = React.useState(false)
if (liked) {
return 'You liked this.';
}
return e(
'button',
{ onClick: () => setLiked(true) },
'Like'
);
}
const domContainer = document.querySelector('#like_button_container');
const root = ReactDOM.createRoot(domContainer);
root.render(e(LikeButton));@andyhwong825 i always use function component. you can test the this code.
@Bobinio please which version of REACT are you using?
good one @okobsamoht , yes that's what I was thinking ,as long as we don't use JSX ,the dom rendring should able to handle both class and function components ; not sure why my first try did not work -any way thanks for confirming it does work.
HI,
Thank you for the example. I could get the example working as it is shown here.
In my case I have a prepackaged React component defined as JSX in project 1. I can do a production build of this project and import the js files in a website project. I am having trouble rendering the React component in the website project. The code in the website looks as follows
'use strict';
const btnContainer1 = document.querySelector('#button_container');
const btnroot = ReactDOM.createRoot(btnContainer1);
// this does not work. It gives console error "ExButton is not defined"
let element = <ExButton type="primary"></ExButton>;
// this works
// let element = <h1>Hello, world</h1>;
btnroot.render(element);
Any suggestion is appreciated.
@JVarghese99 ,I don't see you are importing ExButton component - please do
HI @spicecoder : thank you. I did try importing the ExtButton component in the above javascript but is gave error "require is not defined". I manged to get my example working by exporting the ExtButton in the reactjs project (window as any).ExButton = ExButton
Please see my complete example here https://dev.to/jvarghese/how-to-use-previously-packaged-reactjs-component-in-static-website-21be
@JVarghese99 ,firstly you need to make sure you can generate the component i.e you need to have the full stack of dependent components ,e.g your button component looks like a custom component as well ; once you can generate the component in a reactjs project, then build that project & you should have the right code along with the mimified js that you can bring to your static site
Ok
how to add a color to the 'You liked this' text?
Not working, I'm getting 'require' is not defined
@jo777750
here it is:
if (this.state.liked) {
return e(
'span',
{style:{color:"blue",background:"silver",fontSize:22}},
'You liked this.'
);
}
@Dipsaint1 can you show a screenshot?
@okobsamoht
Thank you for trying to help out.
I've found a solution.
@gaearon How to pass props in button component?
Hi I have resolved this bug, make sure the file name matches the React Component so e.g
<script src="like_button.js"></script>
file name in script must be like_button.js_ they must match and like button will appear
Thank you.
It's working
If I use the three lines of code from this page:
https://reactjs.org/docs/add-react-to-a-website.html
const domContainer = document.querySelector('#like_button_container'); const root = ReactDOM.createRoot(domContainer); root.render(e(LikeButton));
The LIKE button does not appear on the html page.
But if I use just the last two lines in the downloaded js file the LIKE button does appear:
const domContainer = document.querySelector('#like_button_container'); ReactDOM.render(e(LikeButton), domContainer);
I don't know enough js/react to know what the above 3 lines does not work but the 2 lines does.
It is rather troubling especially when I am brand new to react and I am told that the react docs are the best place to learn react and I have flunked on the very first item....
same here i couldnt make it work, weird situation
very nice, thank you
Thank you for this.
Is there a way to re-render the React component based on some action on the HTML page?
For example, changing a date filter and re-rendering the React component with new values for the props (the dates to filter by).

Unzip the downloaded file and open its contents using an IDE of your choice. You can use a live server to publish the content of your html file. The problem is that the script tag is not able to locate the referenced script file.

Try out https://github.com/michaldoda/react-supervisor#readme. Haven't personally tested it, but looks promising.

At the moment I'm looking into https://github.com/michaldoda/react-supervisor#what-it-does. Seems like it might do what you desire, you can give it a shot.
Is it possible to implement the same logic , but for an react-native application ?
Great
Wow this is nice
c'est vraiment génial
