Object 值方法

Object 字段应写入 JSON 兼容的普通对象。读取属性前,先判断未知入参是否为对象。

赋值​

const location = {
address: String(payload.input.address || '').trim(),
city: String(payload.input.city || '').trim(),
};

await context.form.update({
recordId: 'record-id',
data: {
delivery_location: location,
},
});

可接受入参示例:

入参归一化结果
{ address: '...', city: 'Shanghai' }保持对象结构
JSON 文本写入前先解析
null字段允许清空时用于清空

常用方法​

方法用途
Object.keys(value)获取属性名
Object.values(value)获取属性值
Object.entries(value)遍历属性键值对
{ ...value, key: next }生成更新后的对象
value?.property读取可选嵌套属性
const raw = record.data.delivery_location;
const location =
raw && typeof raw === 'object' && !Array.isArray(raw)
? (raw as Record<string, unknown>)
: {};

Object.keys(value)​

获取属性名。

const hasAddress = Object.keys(location).includes('address');

Object.values(value)​

获取属性值。

const filledParts = Object.values(location).filter((value) =>
String(value || '').trim()
);

Object.entries(value)​

遍历属性键值对。

const normalizedLocation = Object.fromEntries(
Object.entries(location).map(([key, value]) => [
key,
typeof value === 'string' ? value.trim() : value,
])
);

{ ...value, key: next }​

生成更新后的对象,不直接修改原对象。

const city = String(location.city || '');
const normalized = {
...location,
city: city.trim(),
};

value?.property​

读取可选嵌套属性。

const coordinates =
location.coordinates &&
typeof location.coordinates === 'object' &&
!Array.isArray(location.coordinates)
? (location.coordinates as Record<string, unknown>)
: null;
const longitude = Number(coordinates?.lng);
