的找到和更换命令链接到对话框插件和似乎没有要通过实例来访问它们的方式，至少不会与未通过通过查询对话。
但是，您可以恢复search.js中的大部分内容，并将其添加为可以传递查询的扩展。但是，您需要设置一个全局对话框或一种方法来获取不依赖实例的查询，并在每个实例上运行它。这样的东西应该工作，这只是用于搜索，但将应便于还有：
CodeMirror.defineExtension('search', function(query) {
// This is all taken from search.js, pretty much as is for the first part.
function SearchState() {
this.posFrom = this.posTo = this.lastQuery = this.query = null;
this.overlay = null;
}
function getSearchState(cm) {
return cm.state.search || (cm.state.search = new SearchState());
}
function searchOverlay(query, caseInsensitive) {
if (typeof query == "string")
query = new RegExp(query.replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, "\\$&"), caseInsensitive ? "gi" : "g");
else if (!query.global)
query = new RegExp(query.source, query.ignoreCase ? "gi" : "g");
return {
token: function(stream) {
query.lastIndex = stream.pos;
var match = query.exec(stream.string);
if (match && match.index == stream.pos) {
stream.pos += match[0].length || 1;
return "searching";
} else if (match) {
stream.pos = match.index;
} else {
stream.skipToEnd();
}
}
};
}
function queryCaseInsensitive(query) {
return typeof query == "string" && query == query.toLowerCase();
}
function parseString(string) {
return string.replace(/\\(.)/g, function(_, ch) {
if (ch == "n") return "\n"
if (ch == "r") return "\r"
return ch
})
}
function parseQuery(query) {
var isRE = query.match(/^\/(.*)\/([a-z]*)$/);
if (isRE) {
try {
query = new RegExp(isRE[1], isRE[2].indexOf("i") == -1 ? "" : "i");
} catch (e) {} // Not a regular expression after all, do a string search
} else {
query = parseString(query)
}
if (typeof query == "string" ? query == "" : query.test(""))
query = /x^/;
return query;
}
// From here it's still from search.js, but a bit tweaked so it applies
// as an extension, these are basically clearSearch and startSearch.
var state = getSearchState(this);
state.lastQuery = state.query;
state.query = state.queryText = null;
this.removeOverlay(state.overlay);
if (state.annotate) {
state.annotate.clear();
state.annotate = null;
}
state.queryText = query;
state.query = parseQuery(query);
this.removeOverlay(state.overlay, queryCaseInsensitive(state.query));
state.overlay = searchOverlay(state.query, queryCaseInsensitive(state.query));
this.addOverlay(state.overlay);
if (this.showMatchesOnScrollbar) {
if (state.annotate) {
state.annotate.clear();
state.annotate = null;
}
state.annotate = this.showMatchesOnScrollbar(state.query, queryCaseInsensitive(state.query));
}
});
// this is to have an external input, but you could have your own way of
// providing your query. Important thing is that you can run search on
// an instance with a query.
const body = document.querySelector('body')
const searchAll = document.createElement('input');
body.appendChild(searchAll);
searchAll.placeholder = 'Search All';
searchAll.addEventListener('input', function(e) {
var query = e.target.value;
var codeMirrorInstances = document.getElementsByClassName('CodeMirror');
for (var i = 0; i < codeMirrorInstances.length; i++) {
var curInst = codeMirrorInstances[i].CodeMirror;
curInst.search(query);
}
});
const title = document.createElement('h1')
title.textContent = 'This is a document with multiple CodeMirrors'
body.appendChild(title);
const area1 = document.createElement('textarea')
body.appendChild(area1)
const editor1 = CodeMirror.fromTextArea(area1, {
lineNumbers: true,
})
const segway = document.createElement('h2')
segway.textContent = 'Moving on to another editor'
body.appendChild(segway)
const area2 = document.createElement('textarea')
body.appendChild(area2)
const editor2 = CodeMirror.fromTextArea(area2, {
lineNumbers: true,
});

编辑：
其他命令，例如FindNext中将正常工作，一旦查询被应用，但当然这也将与实例有关。如果您需要在所有实例中实现findNext，则它变得更加复杂，您需要管理不同的事物，例如当前关注的实例，并且重写某些行为，如循环和诸如此类的某些行为。它可以完成，但取决于您需要的精度级别，它可能非常复杂。像这样的作品，它不是很优雅，但显示它如何做：
CodeMirror.defineExtension('findNext', function(query) {
function SearchState() {
this.posFrom = this.posTo = this.lastQuery = this.query = null;
this.overlay = null;
}
function getSearchState(cm) {
return cm.state.search || (cm.state.search = new SearchState());
}
// You tweak findNext a bit so it doesn't loop and so that it returns
// false when at the last occurence. You could make findPrevious as well
var state = getSearchState(this);
var cursor = this.getSearchCursor(state.query, state.posTo, state.query.toLowerCase());
if (!cursor.find(false)) {
state.posTo = CodeMirror.Pos(0, 0);
this.setSelection(CodeMirror.Pos(0, 0));
return false;
} else {
this.setSelection(cursor.from(), cursor.to());
this.scrollIntoView({
from: cursor.from(),
to: cursor.to()
}, 20);
state.posFrom = cursor.from();
state.posTo = cursor.to();
return true;
}
});
// You make a find next button that will handle all instances
const findNextBtn = document.createElement('button');
body.appendChild(findNextBtn);
findNextBtn.textContent = 'Find next';
findNextBtn.addEventListener('click', function(e) {
// Here you need to keep track of where you want to start the search
// and iterating through all instances.
var curFocusIndex = -1;
var codeMirrorInstances = Array.prototype.slice.call(document.getElementsByClassName('CodeMirror'));
var focusedIndex = codeMirrorInstances.indexOf(lastFocused.getWrapperElement());
// with the new return in findNext you can control when you go to
// next instance
var findInCurCm = lastFocused.findNext();
while (!findInCurCm && curFocusIndex !== focusedIndex) {
curFocusIndex = codeMirrorInstances.indexOf(lastFocused.getWrapperElement()) + 1;
curFocusIndex = curFocusIndex === codeMirrorInstances.length ? 0 : curFocusIndex;
codeMirrorInstances[curFocusIndex].CodeMirror.focus();
lastFocused = codeMirrorInstances[curFocusIndex].CodeMirror;
var findInCurCm = lastFocused.findNext();
}
});

太好了！你会在搜索结果之间跳跃吗？ –
@KyleKelley请参阅编辑，只要您需要管理实例之间的交互，就需要构建一种有效管理它们的方法。实例方法很容易实现，但管理代码镜像实例之间的交互将更加复杂。 –
这很棒，非常感谢。一旦我们开始在我们的开源项目中解决这个问题，我会让你知道它是怎么回事！ –
