可在 rules 中开启 typeMatch,校验当前值是否落在 options 中(multiple 时校验数组元素)。详见表单校验。
{
type: 'select',
name: 'status',
text: '状态',
options: [
{ text: '启用', value: 1 },
{ text: '禁用', value: 0 },
],
rules: [
{ required: true, message: '请选择状态' },
{ typeMatch: true, message: '状态值不合法' },
],
}同时在 src/main.ts 中需要自定义实现请求
app.use(MagicForm, {
request: async (options: any) => {
// 自定义请求实现
},
});TIP
如果 Select 的绑定值为对象类型,请务必指定 valueKey 作为它的唯一性标识。
