ckeditor解决wps复制粘贴问题

1、ckeditor5-paste-from-office插件中space.js中

export function normalizeSpacerunSpans( htmlDocument ) {  

  htmlDocument.querySelectorAll( 'span[style*=spacerun]' ).forEach( el => {

    // Use `el.childNodes[ 0 ].data.length` instead of `el.innerText.length`. For `el.innerText.length` which

    // contains spaces mixed with ` ` Edge browser returns incorrect length.

    if (el.childNodes[ 0 ].data) {

      const innerTextLength = el.childNodes[ 0 ].data.length;

      el.innerHTML = Array( innerTextLength + 1 ).join( '\u00A0 ' ).substr( 0, innerTextLength );

    }

  } );

}

2、ckeditor5-paste-from-office插件中image.js中

function extractImageDataFromRtf( rtfData ) {

  if ( !rtfData ) {

    return [];

  }

  //office

  let regexPictureHeader = /{\\pict[\s\S]+?\\bliptag-?\d+(\\blipupi-?\d+)?({\\\*\\blipuid\s?[\da-fA-F]+)?[\s}]*?/;

  let regexPicture = new RegExp( '(?:(' + regexPictureHeader.source + '))([\\da-fA-F\\s]+)\\}', 'g' );

  let images = rtfData.match( regexPicture );

  let result = [];

  if ( !images ) {

    regexPictureHeader = /{\\pict[\s\S]+?(\\pngblip-?\d+)?(\\wmetafile8-?\d+)?{\\\*\\blipuid\s?[\da-fA-F]+[\s}]*?/;

    regexPicture = new RegExp( '(?:(' + regexPictureHeader.source + '))([\\da-fA-F\\s]+)\\}', 'g' );

    images = rtfData.match( regexPicture );

  }

  if ( images ) {

    for ( const image of images ) {

      let imageType = false;

      if ( image.includes( '\\pngblip' ) ) {

        imageType = 'image/png';

      } else if ( image.includes( '\\jpegblip' ) ) {

        imageType = 'image/jpeg';

      }

      if ( imageType ) {

        result.push( {

          hex: image.replace( regexPictureHeader, '' ).replace( /[^\da-fA-F]/g, '' ),

          type: imageType

        } );

      }

    }

  }

  return result;

}
