How to control events in the content?

[petkovic43]

Hello, I'm having trouble changing the content from a user action within the content itself. I am creating an input similar to facebook, that when the user informs a url, the system obtains the page's meta tags and a card is created as in the image below. However, by clicking on the "x" on the card I would like it to be removed, but I can't change the text.current anymore. Does anyone have any idea how to solve? Follow my code

import React, { useRef, useState, memo } from 'react';
import ContentEditable from 'react-contenteditable'
import sanitizeHtml from 'sanitize-html';
import { MdPhotoCamera, MdOndemandVideo, MdLink } from 'react-icons/md'
import api from 'lib/api';

const clean = content => sanitizeHtml(content, {
  allowedTags: ['h5', 'p', 'a', 'nl', 'hr', 'br', 'div', 'iframe', 'img', 'button', 'span'],
  disallowedTagsMode: 'discard',
  allowedAttributes: {
    a: ['href', 'name'],
    iframe: ['src', 'width', 'height', 'frameborder', 'allow', 'allowfullscreen'],
    img: ['src', 'style', 'class', 'alt'],
    div: ['contenteditable', 'class', 'style'],
    h5: ['class'],
    p: ['class'],
    button: ['class', 'type'],
    span: ['aria-hidden', 'class']
  },
  // Lots of these won't come up by default because we don't allow them
  selfClosing: ['img', 'br', 'hr'],
  // URL schemes we permit
  allowedSchemes: ['http', 'https', 'data'],
  allowedSchemesByTag: {},
  allowedSchemesAppliedToAttributes: ['href', 'src'],
  allowProtocolRelative: true,
  enforceHtmlBoundary: false,
  allowedIframeHostnames: ['www.youtube.com', 'player.vimeo.com'],
  transformTags: {
    'img': (tagName, attribs) => ({
      tagName,
      attribs: {
        ...attribs,
        style: 'max-width: 100%;',
      }
    }),
    'iframe': (tagName, attribs) => ({
      // My own custom magic goes here
      tagName,
      attribs: {
        ...attribs,
        width: '100%;',
        height: '300',
        frameborder: '0',
        allow: "accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture",
        allowfullscreen: true
      }
    })
  }
});

const NewPost = () => {
  const [loading, setLoading] = useState(false)
  const text = useRef(clean(''))
  const [loadedDiv, setLoadedDiv] = useState(false)
  const handleChange = async ({ target: { value } }) => {
    const href = value.match(/href="([^"]*")/g)
    if (href) {
      if (!loadedDiv) {
        setLoading(true)
        text.current = clean([value, bounce].join(''));
        const { data } = await api.get(`/meta?url=${href[0].split('"')[1]}`)
        text.current = clean([value, card(data)].join(''));
        setLoading(false)
        setLoadedDiv(true)
      } else {
        text.current = clean(value);
      }
    } else {
      setLoadedDiv(false)
      text.current = clean(value);
    }
  };


  const handleClick = ({ target: { className } }) => {
    console.log(className)
    if (className === "close text-white position-absolute pos-top pos-right p-2 m-1 mr-2" || className === 'close_card_url') {
      console.log(text);
      text.current = '';
    }
  }

}

export default memo(NewPost);

You can use innerRef to get a reference to the editable DOM element. But in my opinion, your ssmart card should not be part of the contenteditable element.

@lovasoa
i Have similar query
I want to change the content with events based on conditions .
i am able to alter text.current but the same is not rendered in the UI.

coinsider this example for illustration purpose.

     const handleChange = evt => {
            text.current = evt.target.value + 'A'
        console.log(text.current);   // gives  evt.target.value + 'A'   but renders only evt.target.value
  }
     <ContentEditable 
                 html={text.current} 
                 onChange={handleChange} 
                 onBlur={handleBlur}
                '/>
