# --description--
|
||
|
||
我們嘗試一種最簡單的用法，`Model.find()` 接收一個查詢 document（一個 JSON 對象）作爲第一個參數，一個回調函數作爲第二個參數， 它會返回由匹配到的數據組成的數組。 這個方法支持很多搜索選項， 詳情請參閱文檔。
|
||
|
||
# --instructions--
|
||
|
||
修改 `findPeopleByName` 函數使用 <code>Model.find() -\> [Person]</code> 查詢所有給定名字的人。
|
||
|
||
請使用函數參數中的 `personName` 作爲搜索條件。
|
||
|
||
# --hints--
|
||
|
||
應成功地找到所有符合條件的數據
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.post(getUserInput('url') + '/_api/find-all-by-name', {
|
||
name: 'r@nd0mN4m3',
|
||
age: 24,
|
||
favoriteFoods: ['pizza']
|
||
}).then(
|
||
(data) => {
|
||
assert.isArray(data, 'the response should be an Array');
|
||
assert.equal(
|
||
data[0].name,
|
||
'r@nd0mN4m3',
|
||
'item.name is not what expected'
|
||
);
|
||
assert.equal(data[0].__v, 0, 'The item should be not previously edited');
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.responseText);
|
||
}
|
||
);
|
||
```
