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;
}
