拖了很久，总算是自己写了一个简单的代码编辑组件，虽然还有不少的bug，真的很难写，在写的过程中感觉自己的前端技术根本不够用，好像总是方案不够好；目前写出了这个效果，等待后续学习别的现有产品，再慢慢补充

采用div的设置可编辑属性 contenteditable=“true”，然后结合 highlight的代码高亮，效果还不错；最开始相加的代码输入提示，以为不难实现，但是真的写起来，总是没有办法很好的实现那个输入面板的位置控制；索性就暂时不加输入提示，然后搜索功能，也是有不小的难点；目前仍然存在着一些bug待修复，但是可以先作为小demo试用一下

目前算是完成第一阶段，虽然组件的功能不是很完善，但是基本的代码高亮和搜索功能也有了，算是差强人意啦

核心代码

输入组件

<script setup>

});const search = useSearchStore();function refresh() {const height = inputElem.scrollHeight;const number = Math.ceil(height / 21);if (number !== data.lineNumber.length) {data.lineNumber = [];for (let i = 0; i < number; i++) {data.lineNumber.push(i + 1);}}if (search.showSearch) {search.search(false);}
}let leftLineNumberContainer;
let rightInputArea;
let inputElem;function syncScroll(event) {if (event.target === leftLineNumberContainer) {rightInputArea.scrollTo({top: event.target.scrollTop,});}if (event.target === rightInputArea) {leftLineNumberContainer.scrollTo({top: event.target.scrollTop,});}
}function inputFocus() {inputElem.focus();const range = document.createRange();range.selectNodeContents(inputElem);range.collapse(false);const sel = window.getSelection();sel.removeAllRanges();sel.addRange(range);if (!leftLineNumberContainer) {leftLineNumberContainer = document.getElementsByClassName("left-line-number-container")[0];}if (!rightInputArea) {rightInputArea = document.getElementsByClassName("right-input-area")[0];}leftLineNumberContainer.scrollTo({top: rightInputArea.scrollHeight,});rightInputArea.scrollTo({top: rightInputArea.scrollHeight,});
}onMounted(() => {inputElem = document.getElementsByClassName("input-elem")[0];rightInputArea = document.getElementsByClassName("right-input-area")[0];search.rightInputArea = rightInputArea;search.inputElem = inputElem;search.language = data.language;search.refresh = refresh;inputFocus();
});function getPasteData(event) {const clipData = event.clipboardData || window.clipboardDataconst value = clipData.getData('text/plain');let highlightedCode = hljs.highlight(value, {language: data.language}).value;const container = document.createElement("span");container.innerHTML = highlightedCode;function wrapTextNodesInSpan(element) {for (let i = 0; i < element.childNodes.length; i++) {const child = element.childNodes[i];if (child.nodeType === Node.TEXT_NODE) {const span = document.createElement('span');span.textContent = child.nodeValue;element.insertBefore(span, child);element.removeChild(child);} else if (child.nodeType === Node.ELEMENT_NODE) {wrapTextNodesInSpan(child);}}}wrapTextNodesInSpan(container);appendDom(rightInputArea, container);refresh();
}function keydown(event) {search.keydown(event);if (event.key === "Tab") {event.preventDefault();appendContent("  ");}if (event.ctrlKey) {return;}if (event.key === "Enter" || event.key === "Backspace" || event.key === "Delete") {setTimeout(() => {refresh();}, 10);return;}if (isAlphaNumeric(event.key)) {event.preventDefault();appendContent(event.key);refresh();}
}function isAlphaNumeric(key) {return /^[a-zA-Z0-9]$/.test(key);
}function appendContent(content) {const span = document.createElement("span");span.textContent = content;appendDom(rightInputArea, span, false);
}
