Ace 편집기에서 코드의 일부를 읽기 전용으로 만들려고했습니다.
JsFiddle에 제공된 코드를 사용하여 시도했습니다.
$(function() {
var editor = ace.edit("editor1")
, session = editor.getSession()
, Range = require("ace/range").Range
, range = new Range(1, 4, 1, 10)
, markerId = session.addMarker(range, "readonly-highlight");
session.setMode("ace/mode/javascript");
editor.keyBinding.addKeyboardHandler({
handleKeyboard : function(data, hash, keyString, keyCode, event) {
if (hash === -1 || (keyCode <= 40 && keyCode >= 37)) return false;
if (intersects(range)) {
return {command:"null", passEvent:false};
}
}
});
before(editor, 'onPaste', preventReadonly);
before(editor, 'onCut', preventReadonly);
range.start = session.doc.createAnchor(range.start);
range.end = session.doc.createAnchor(range.end);
range.end.$insertRight = true;
function before(obj, method, wrapper) {
var orig = obj[method];
obj[method] = function() {
var args = Array.prototype.slice.call(arguments);
return wrapper.call(this, function(){
return orig.apply(obj, args);
}, args);
}
return obj[method];
}
function intersects(range) {
return editor.getSelectionRange().intersects(range);
}
function preventReadonly(next, args) {
if (intersects(range)) return;
next();
}
});
백 스페이스 키를 계속 누르면 읽기 전용 부분으로 들어가고 편집 가능한 부분이 남지 않았습니다.
여러 코드 청크를 읽기 전용으로 만들고 마지막 문자가 읽기 전용으로 삭제되는 것을 방지하려면 어떻게해야합니까?
또한 편집 가능한 부분을 지정하는 텍스트에 마커가있는 곳에서 모든 것을 동적으로 달성하는 방법은 무엇입니까?
되돌릴 수없는 삭제 및 드래그 / 드롭 처리를 방지하기 위해 범위 끝에서 Enter를 사용하여 여러 줄의 읽기 전용을 허용하는 아래 코드를 확인하십시오.
