Angularjs中如何使用filterFilter函数过滤

AngularJS的filter，中文名“过滤器”是用来过滤变量的值，或者格式化输出，得到自己所期望的结果或格式的东东。AngularJS中有一个filterFilter函数用来对集合过滤，非常方便。

源代码大致如下：

function filterFilter(){
return function(aray, expression comparator){
if(!isArray(array)) return array;
var comparatorType = typeof(comparator),
predicates = [],
evaluatedObjects = [];
predicates.check = function(value){
for(var j = 0; j < predicates.length; jii){
if(!predicates[j](value){
return false;
})
}
return true;
} 
if(comparatorType != 'function'{
if(comparatorType === 'boolean' && comparator){
comparator = function(obj, text){
return angular.equals(obj, text);
}
} else {
comparator = function(obj, text){
...
}
}
}) 
}
}

controller部分如下：

angular
.module('app')
.controller('MainCtrl', ['$scope',
function($scope) {
$scope.users = $scope.users = [
{name: '', email: '', joined: 2015-1-1}
];
$scope.filter = {
fuzzy: '',
name: ''
};
...
}]);

搜索所有任意字段

{{user.name}}
{{user.email}}
{{user.joined | date}}

搜索某个字段

{{user.name}}
{{user.email}}
{{user.joined | date}}

如果想name字段完全匹配：

{{user.name}}
{{user.email}}
{{user.joined | date}}

搜索时间段

contrlller部分修改为：

angular
.module('app')
.controller('MainCtrl', ['$scope',
function($scope) {
$scope.users = $scope.users = [
{name: '', email: '', joined: 2015-1-1}
];
$scope.filter = {
fuzzy: '',
name: ''
};
$scope.minDate = new Date('January 1, 2000');
$scope.maxDate = new Date();
$scope.min = function(actual, expected) {
return actual >= expected;
};
$scope.max = function(actual, expected) {
return actual <= expected;
};
}]);

页面部分为：

{{user.name}}
{{user.email}}
{{user.joined | date}}
