Question

一般都是這樣寫過濾，但是我想只針對一部分數據，phone.name實現過濾這個要如何實現呢？ ？

根據官方文件的描述，有幾種方式來實現：
{{ filter_expression | filter : expression : comparator}}

1.如Guox給出的方法,使用expression:

Object: A pattern object can be used to filter specific properties on objects contained by array. For example {name:"M", phone:"1"} predicate will return an array of itemsms whichnty name" property phone containing "1".

作為Object使用，用於過濾數組元素的指定屬性，如expression = {name:"M", phone:"1"} ，那麼將會過濾出數組中name包含'M'且phone包含'1'的元素。

故使用以下方法即可

<li ng-repeat="phone in phones|filter:{name:query}">

2.可以使用comparator：

Comparator which is used in determining if the expected value (from the filter expression) and actual value (from the object in the array) should be considered a match.
function(actual, expect ): match.

function(actual, expect. and the predicate value to compare and should return true if both values should be considered equal.

透過Comparator的回傳值能夠決定是否匹配，入參分別是actual（陣列中的元素）和expected（輸入）

那麼定義一個函數🎜

$scope.customerFilter = customerFilter;

function customerFilter(actual, expected){
    return actual.name.contains(expexted) ? true : false;
}

前端使用
<li ng-repeat="phone in phones|filter:query:customerFilter">
