结束了使用replaceWith的以下内容。
可能是一个更好的解决方案,但希望这对其他人有所帮助。
见内联评论:
const execute = (casing, state, dispatch) => {
// grab the current transaction and selection
let tr = state.tr;
const selection = tr.selection;
// check we will actually need a to dispatch transaction
let shouldUpdate = false;
state.doc.nodesBetween(selection.from, selection.to, (node, position) => {
// we only processing text, must be a selection
if (!node.isTextblock || selection.from === selection.to) return;
// calculate the section to replace
const startPosition = Math.max(position + 1, selection.from);
const endPosition = Math.min(position + node.nodeSize, selection.to);
// grab the content
const substringFrom = Math.max(0, selection.from - position - 1);
const substringTo = Math.max(0, selection.to - position - 1);
const updatedText = node.textContent.substring(substringFrom, substringTo);
// set the casing
const textNode = (casing === 'uppercase')
? state.schema.text(updatedText.toUpperCase(), node.marks)
: state.schema.text(updatedText.toLocaleLowerCase(), node.marks);
// replace
tr = tr.replaceWith(startPosition, endPosition, textNode);
shouldUpdate = true;
});
if (dispatch && shouldUpdate) {
dispatch(tr.scrollIntoView());
}
}
