我正在使用Quill JS作为富文本编辑器。如果用户单击按钮，我希望能够突出显示文本中的特定单词。但 Quill JS 似乎没有授予通过另一个插件编辑其内容的权限(？)
我试过Mark.js和 Highlight.js ，但它们仅适用于 Quill JS 编辑器中不存在的元素。不过，触发器似乎有效，因为带有正确关键字的
行在 Firefox Inspector 中闪烁，就像有东西访问该行一样，但在浏览器中没有真正的变化。
我发布了一些示例代码(请忽略Javascript的第一部分，因为它只是我必须放在那里的highlight.js插件。我的自定义代码位于最后):
$( document ).ready(function() {
// My custom code is at the very end. This is the highlight.js plugin code:
// Copyright (c) 2009 Bartek Szopka
jQuery.extend({
highlight: function (node, re, nodeName, className) {
if (node.nodeType === 3) {
var match = node.data.match(re);
if (match) {
var highlight = document.createElement(nodeName || 'span');
highlight.className = className || 'highlight';
var wordNode = node.splitText(match.index);
wordNode.splitText(match[0].length);
var wordClone = wordNode.cloneNode(true);
highlight.appendChild(wordClone);
wordNode.parentNode.replaceChild(highlight, wordNode);
return 1; //skip added node in parent
}
} else if ((node.nodeType === 1 && node.childNodes) && // only element nodes that have children
!/(script|style)/i.test(node.tagName) && // ignore script and style nodes
!(node.tagName === nodeName.toUpperCase() && node.className === className)) { // skip if already highlighted
for (var i = 0; i < node.childNodes.length; i++) {
i += jQuery.highlight(node.childNodes[i], re, nodeName, className);
}
}
return 0;
}
});
jQuery.fn.unhighlight = function (options) {
var settings = { className: 'highlight', element: 'span' };
jQuery.extend(settings, options);
return this.find(settings.element + "." + settings.className).each(function () {
var parent = this.parentNode;
parent.replaceChild(this.firstChild, this);
parent.normalize();
}).end();
};
jQuery.fn.highlight = function (words, options) {
var settings = { className: 'highlight', element: 'span', caseSensitive: false, wordsOnly: false };
jQuery.extend(settings, options);
if (words.constructor === String) {
words = [words];
}
words = jQuery.grep(words, function(word, i){
return word != '';
});
words = jQuery.map(words, function(word, i) {
return word.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, "\\$&");
});
if (words.length == 0) { return this; };
var flag = settings.caseSensitive ? "" : "i";
var pattern = "(" + words.join("|") + ")";
if (settings.wordsOnly) {
pattern = "\\b" + pattern + "\\b";
}
var re = new RegExp(pattern, flag);
return this.each(function () {
jQuery.highlight(this, re, settings.element, settings.className);
});
};

不支持通过 DOM API 进行任意更改。要更改 Quill 的编辑器内容，您必须使用其 API 。这个Cloning Medium with Parchment指南对于创建您所描述的新格式非常有用。
