搜索数值时,我的过滤器出现问题。 我希望在“matricule”上进行精确搜索(使用custum过滤器),但这是我的代码中的一个问题,我不知道。 这是我的索引:
<html>
<head>
<meta charset='utf-8'>
<script src="js/angular.js"></script>
<script src="js/app.js"></script>
<link rel="stylesheet" href="css/bootstrap.css">
</head>
<body ng-app="MyApp">
<div ng-controller="MyCtrl">
<h3>Filter by numeric value</h3>
<form class="form-inline">
<input ng-model="match.matricule" type="text" placeholder="Filter by matricule" autofocus>
</form>
<ul ng-repeat="friend in (result = (friends | exact: match ) ) ">
<li>{{friend.matricule}} - {{friend.name}} ({{friend.age}})</li>
</ul>
<p ng-show="result.length == 0"> Not Found </p>
{{result}}
</div>
</body>
</html>
这是我的控制者:
var app = angular.module("MyApp", []);
app.controller("MyCtrl", function($scope) {
$scope.friends = [
{ matricule :1 , name: "Peter", age: 20 , region : 'analamanga1'},
{ matricule :2 ,name: "Pablo", age: 55 , region : 'analamanga2'},
{ matricule :3 ,name: "Linda", age: 20 , region : 'analamanga3'},
{ matricule :4 ,name: "Marta", age: 37 , region : 'analamanga4'},
{ matricule :5 ,name: "Othello", age: 20 , region : 'analamanga5'},
{ matricule :11 ,name: "Markus", age: 32 , region : 'analamanga6'}
];
$scope.filterFunction = function(element) {
return element.name.match(/^Ma/) ? true : false;
};
})
app.filter('exact', function(){
return function(items, match){
var matching = [], matches, falsely = true;
// Return the items unchanged if all filtering attributes are falsy
angular.forEach(match, function(value, key){
falsely = falsely && !value;
});
if(falsely){
return items;
}
angular.forEach(items, function(item){
matches = true;
angular.forEach(match, function(value, key){ // e.g. 'all', 'title'
if(!!value){
matches = matches && (item[key] === value);
}
});
if(matches){
matching.push(item);
}
});
return matching;
}
});

Omg ...如果你只想要过滤这个你做得那么难,你可以使用角度滤镜让它变得如此简单,你只需要这样做:
HTML:
<html>
<head>
<meta charset='utf-8'>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-app="MyApp">
<div ng-controller="MyCtrl">
<h3>Filter by numeric</h3>
<form class="form-inline">
<input ng-model="match.matricule" type="text" placeholder="Filter by matricule" autofocus>
</form>
<ul ng-repeat="friend in friends | filter:match:strict">
<li>{{friend.matricule}} - {{friend.name}} ({{friend.age}})</li>
</ul>
<p ng-show="result.length == 0"> Not Found </p>
</div>
</body>
</html>
CONTROLLER
var app = angular.module("MyApp", []);
app.controller("MyCtrl", function($scope) {
$scope.friends = [
{ matricule :1 , name: "Peter", age: 20 , region : 'analamanga1'},
{ matricule :2 ,name: "Pablo", age: 55 , region : 'analamanga2'},
{ matricule :3 ,name: "Linda", age: 20 , region : 'analamanga3'},
{ matricule :4 ,name: "Marta", age: 37 , region : 'analamanga4'},
{ matricule :5 ,name: "Othello", age: 20 , region : 'analamanga5'},
{ matricule :11 ,name: "Markus", age: 32 , region : 'analamanga6'}
];
});

好的,对不起我没有理解你的问题。让我们试试这个:
HTML:
<html>
<head>
<meta charset='utf-8'>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-app="MyApp">
<div ng-controller="MyCtrl">
<h3>Filter by numeric</h3>
<form class="form-inline">
<input ng-model="matricule" type="text" placeholder="Filter by matricule" autofocus>
</form>
<ul ng-repeat="friend in friends | filter:myFilter">
<li>{{friend.matricule}} - {{friend.name}} ({{friend.age}})</li>
</ul>
<p ng-show="result.length == 0"> Not Found </p>
</div>
</body>
</html>
控制器:
var app = angular.module("MyApp", []);
app.controller("MyCtrl", function($scope) {
$scope.friends = [
{ matricule :1 , name: "Peter", age: 20 , region : 'analamanga1'},
{ matricule :2 ,name: "Pablo", age: 55 , region : 'analamanga2'},
{ matricule :3 ,name: "Linda", age: 20 , region : 'analamanga3'},
{ matricule :4 ,name: "Marta", age: 37 , region : 'analamanga4'},
{ matricule :5 ,name: "Othello", age: 20 , region : 'analamanga5'},
{ matricule :11 ,name: "Markus", age: 32 , region : 'analamanga6'}
];
$scope.myFilter = function (data) {
if ($scope.matricule === '' || !$scope.matricule) return true;
var reg = RegExp("^" + $scope.matricule + "$");
return reg.test(data.matricule);
};
});
---------更新v2 -----
显示&#34; none&#34;如果搜索字段为空,则从列表中删除需要保存的结果:

</form>
<ul ng-repeat="friend in (filteredItems = (friends | filter:myFilter))">
