问题描述
<li ng-repeat='phone in phones|filter:query'>
一般都是这样写过滤，但是我想只针对一部分数据，phone.name实现过滤这个要如何实现呢？？
问题解答
回答1：<li ng-repeat='phone in phones|filter:{’name’: query}'>
回答2：根据官方文档的描述，有几种方式来实现：{{ filter_expression | filter : expression : comparator}}
1.如Guox给出的方法,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 items which have property name containing 'M' and property phone containing '1'.
作为Object使用，用于过滤数组元素的指定属性，如expression = {name:'M', phone:'1'} ，那么将会过滤出数组中name包含’M’且phone包含’1’的元素。
故使用如下方法即可
<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, expected): The function will be given the object value and the predicate value to compare and should return true if both values should be considered equal.
通过Comparator的返回值能够决定是否匹配，入参分别是actual（数组中的元素）和expected（输入）
那么定义一个函数
$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'>回答3：
太感谢二位了，谢谢
