# 实现方案 — 撤销栈修复、字段删除交互优化与签名字段闭环(2026-04-17-12-34-56)
## 一、修改文件清单
1. `src/pages/TemplateManage.tsx` — 删除逻辑改用 `execCommand('delete')`;插入 HTML 增加零宽空格防换行
2. `src/types.ts` — 修改 `surgeonSignature` 显隐属性;新增 `isSigned` 字段
3. `src/pages/ReportEditor.tsx` — 初始值增加 `isSigned`;签名同步逻辑重构;完成报告签名校验
4. `src/index.css` — 签名图片尺寸约束
5. `src/utils/print.ts` — 打印样式同步签名尺寸约束
## 二、详细改动
### 2.1 `src/pages/TemplateManage.tsx`
#### A. 点击红 X 删除改用 `execCommand('delete')`
```ts
if (smartField && targetEl.closest('.delete-btn')) {
e.stopPropagation();
e.preventDefault();
const sel = window.getSelection();
const range = document.createRange();
range.selectNode(smartField);
sel?.removeAllRanges();
sel?.addRange(range);
document.execCommand('delete');
saveTemplateContent();
return;
}
```
#### B. 键盘 Backspace/Delete 改用 `execCommand('delete')`
在 `handleKeyDown` 中,当定位到 `smart-field-wrapper` 目标后:
```ts
if (target) {
e.preventDefault();
const sel = window.getSelection();
const range = document.createRange();
range.selectNode(target);
sel?.removeAllRanges();
sel?.addRange(range);
document.execCommand('delete');
saveTemplateContent();
}
```
#### C. 插入 HTML 防换行
在 `insertSmartField` 的 HTML 字符串末尾增加 ``(零宽空格),作为行内锚点,防止浏览器将字段挤到新行:
```html
...
```
### 2.2 `src/types.ts`
- 将 `surgeonSignature` 改为:
```ts
{ key: 'surgeonSignature', label: '手术者签名', category: '图片', type: 'signature', visibleInForm: true, isSystemLocked: false }
```
- 在 `DEFAULT_FORM_FIELDS` 末尾追加(放在 `surgeonSignature` 之前或之后均可):
```ts
{ key: 'isSigned', label: '手术者签名确认', category: '单选', type: 'single_select', visibleInForm: true, isSystemLocked: false, options: ['已签字', '未签字'] },
```
### 2.3 `src/pages/ReportEditor.tsx`
#### A. 初始 `reportData` 增加 `isSigned`
```ts
const [reportData, setReportData] = useState>({
// ... 其他字段
isSigned: '未签字',
// ...
});
```
#### B. 签名同步逻辑重构
将 `surgeonSignature` 的特殊处理从 `useEffect` 移到更前面的位置,逻辑改为:
```ts
if (fieldKey === 'surgeonSignature') {
const isSigned = (reportData as any).isSigned === '已签字';
const signatureData = currentUser?.signature;
if (isSigned && signatureData) {
const imgHtml = `
`;
if (el.innerHTML !== imgHtml) {
el.innerHTML = imgHtml;
el.style.border = 'none';
el.style.backgroundColor = 'transparent';
}
} else {
const placeholder = isSigned ? '【请上传电子签】' : '【未签字】';
if (el.innerText !== placeholder) {
el.innerText = placeholder;
el.style.border = '';
el.style.backgroundColor = '';
}
}
return;
}
```
#### C. 完成报告签名校验
在 `saveReport` 的 `status === 'completed'` 分支中,在现有患者信息校验之后追加:
```ts
const hasSignatureField = editorRef.current?.querySelector('[data-bind="surgeonSignature"]');
if (hasSignatureField) {
const isSigned = reportData.isSigned === '已签字';
const hasSignatureImage = !!currentUser?.signature;
if (!isSigned) {
const proceed = window.confirm('提示:模板中包含【手术者签名】字段,但您在基本信息中未选择"已签字"。是否继续完成报告?');
if (!proceed) return;
} else if (!hasSignatureImage) {
const proceed = window.confirm('提示:您选择了"已签字",但您的账号尚未上传电子签名图片。报告中将不显示签名图片,是否继续完成?');
if (!proceed) return;
}
}
```
### 2.4 `src/index.css`
修改 `.report-signature-img`:
```css
.report-signature-img {
max-width: 120px;
max-height: 40px;
width: auto;
height: auto;
object-fit: contain;
vertical-align: middle;
display: inline-block;
}
```
在 `@media print` 中同步:
```css
@media print {
.report-signature-img {
max-width: 120px !important;
max-height: 40px !important;
width: auto !important;
height: auto !important;
object-fit: contain !important;
vertical-align: middle !important;
display: inline-block !important;
}
}
```
### 2.5 `src/utils/print.ts`
在 iframe 的 `
