参数名
返回值
Promise<IPCB_PrimitiveAttribute | undefined>
文本图元对象
示例
javascript
// 1. 放置测试器件并添加自定义属性（随机坐标避免与画布已有器件重合）：
// 按立创编号从系统库精确反查器件，返回项不含 libraryUuid，需补上才能用于 create
const x = 20000 + Math.floor(Math.random() * 80000);
const y = 20000 + Math.floor(Math.random() * 80000);
const devices = await eda.lib_Device.searchByProperties({ supplierId: 'C1523' }, undefined, undefined, undefined, 5, 1);
const sysLibUuid = await eda.lib_LibrariesList.getSystemLibraryUuid();
const comp = await eda.pcb_PrimitiveComponent.create({ libraryUuid: sysLibUuid, uuid: devices[0].uuid }, 1, x, y);
const compId = comp.getState_PrimitiveId();
await comp.setAttribute('嘉立创示例_Tolerance', '1%', true, true);
// 2. 找到自定义属性的图元并读取修改前的值
const attrIds = await eda.pcb_PrimitiveAttribute.getAllPrimitiveId(compId);
const attrs = await eda.pcb_PrimitiveAttribute.get(attrIds);
const target = attrs.find(a => a.getState_Key() === '嘉立创示例_Tolerance');
const beforeValue = target.getState_Value();
const beforeFontSize = target.getState_FontSize();
// 3. 批量修改：属性值 1% → 5%，字号 45 → 60
await eda.pcb_PrimitiveAttribute.modify(target.getState_PrimitiveId(), { value: '5%', fontSize: 60 });
// 4. modify 返回后需要重新 get() 才能读到画布上的最新值
const refreshed = await eda.pcb_PrimitiveAttribute.get(target.getState_PrimitiveId());
// 5. 修改类保留现场，供观察修改结果
console.log('value:', beforeValue, '→', refreshed.getState_Value());
console.log('fontSize:', beforeFontSize, '→', refreshed.getState_FontSize());1
