我想进行过滤，以便当 color.name 的值也作为 cars.color 中的值出现时，我可以显示它们
$scope.colors = [{"name":"blue","count":2},
{"name":"red","count":12},
{"name":"pink","count":5},
{"name":"yellow","count":2}];
$scope.cars=[ {"brand":"Ford","color":"blue", "seat":"pink"}
,{"brand":"Ferrari","color":"red", "seat":"pink"}
,{"brand":"Rolls","color":"blue","seat":"pink"}];
然后在 View 中:
<ul>
<li ng-repeat="n in colors | filter: filteredColors"> {{n}}
</li>
</ul>
结果应该是
我需要答案是没有 ES6，并且我需要将过滤器放在 Controller 中。请参阅 plunkr here 。提前致谢!
最佳答案
Controller :
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.colors = [{"name":"blue","count":2},
{"name":"red","count":12},
{"name":"pink","count":5},
{"name":"yellow","count":2}];
$scope.cars=[ {"brand":"Ford","color":"blue", "seat":"pink"}
,{"brand":"Ferrari","color":"red", "seat":"pink"}
,{"brand":"Rolls","color":"blue","seat":"pink"}];
$scope.filteredColors = function(color) {
var carsvar = $scope.cars;
for(var x = 0; x < carsvar.length; x++) {
if (color.name === carsvar[x].color) {
return true;
}
}
return false;
};
});
