使用过滤器显示数组中多个匹配值

我无法显示多值表单文本框，即输入的值与我们需要显示匹配值的数组值匹配，对于我只显示一个值。请帮我找出解决方案。在这个例子中，如果输入“ball”它显示，如果我们输入“ball all”它必须同时显示“ball”“all”但是因为它没有显示bcoz这里我们不返回一个数组如果我赋值给数组，错误。任何人都可以帮我解决我犯的错误。使用过滤器显示数组中多个匹配值

var app = angular.module('angularPracticeApp'); 
 
    app.controller('AppController', function ($scope) { 
 
    $scope.match = {}; 
 
     $scope.words = [ 
 
      { title: "ball", type: 'object' }, 
 
      { title: "wall", type: 'object' }, 
 
      { title: "all", type: 'word' }, 
 
      { title: "alloy", type: 'material' } 
 
     ]; 
 
    
 
}); 
 
    
 
    app.filter('exact', function(){ 
 
    return function(items, match){ 
 
    var matching = [], matches,resultArray = []; 
 
    
 
    angular.forEach(items, function(item){ // e.g. { title: "ball" } 
 
     matches = true; 
 
     angular.forEach(match, function(value, key){ // e.g. 'all', 'title' 
 

 
     \t var stringArray = value.split(/(\s+)/);

抱歉无法调试您的过滤器，所以我做了我自己，请用它作为参考。

JSFiddle Demo

JS：

var app = angular.module('myApp', []); 

app.controller('MyController', function MyController($scope) { 

    $scope.match = {}; 
     $scope.words = [ 
      { title: "ball", type: 'object' }, 
      { title: "wall", type: 'object' }, 
      { title: "all", type: 'word' }, 
      { title: "alloy", type: 'material' } 
     ]; 

}); 
app.filter('exact', function($filter){ 
    return function(items, match){ 
    console.log(match); 
    if(Object.keys(match).length !== 0){ 
     match = match.title.split(" "); 
    }else{ 
    console.log("itesm", items); 
     return items; 
    } 
     if(match){ 
      return $filter("filter")(items, function(listItem){ 
       return match.indexOf(listItem.title) != -1; 
      }); 
     } 
    }; 
});

谢谢那仁穆拉利它的正常工作。 – raj

@raj不客气:) –

好吧，我想我明白你想要什么，我觉得可能是更好的方法。这里的解决方案，我为你准备的，它是干净多了：

http://jsfiddle.net/U3pVM/33950/ HTML：

<div ng-app> 
    <div ng-controller="SomeCtrl"> 
    <div> 
     Find words that exactly match title: 
     <input ng-model="match.title" /> 
     <br> 

     <table> 
     <tr ng-repeat="word in wordsCopy"> 
      <td>{{word.title}}</td> 
     </tr> 
     </table> 
    </div> 
    </div> 
</div>

和JS：

function SomeCtrl($scope) { 
    $scope.words = [{ 
    title: "ball", 
    type: 'object' 
    }, { 
    title: "wall", 
    type: 'object' 
    }, { 
    title: "all", 
    type: 'word' 
    }, { 
    title: "alloy", 
    type: 'material' 
    }]; 
    $scope.wordsCopy = $scope.words; 
    $scope.$watch('match.title', (newVal, oldVal) => { 
    if (newVal) { 
     $scope.wordsCopy = $scope.words.filter((val, index) => { 
     return newVal.split(' ').indexOf(val.title) !== -1; 
     }); 
    } else { 
     $scope.wordsCopy = $scope.words; 
    } 
    }); 
};
