我正在使用 ng-repeat 作为数组 json 值。但我想从 UI(HTML) 中删除重复值。就像 Car 值重复一样，所以我想删除重复的键值。应该来一次。
var app = angular.module('testApp',[]);
app.controller('testCtrl',function($scope){
$scope.res ={};
$scope.res.fsus = [
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "var"
}
}
}
},
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "car"
}
}
}
},
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "car"
}
}
}
},
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "car"
}
}
}
},
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "ban"
}
}
}
}
];
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="testApp" ng-controller="testCtrl">
<li ng-repeat="test in res.fsus track by $index">
<span class="step"> {{test.statusMessageType.MasterConsignment.ReportedStatus.ReasonCode}}
</span>
</li>
</body>您不必使用任何外部库，只需使用 angular.forEach 删除重复元素，
angular.forEach($scope.res.fsus,function(key,value){
if(($scope.opts.indexOf(key.statusMessageType.MasterConsignment.ReportedStatus.ReasonCode , 0)) <= -1){ $scope.opts.push(key.statusMessageType.MasterConsignment.ReportedStatus.ReasonCode);
};
});
演示
var app = angular.module('testApp',[]);
app.controller('testCtrl',function($scope){
$scope.res ={};
$scope.res.fsus = [
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "var"
}
}
}
},
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "car"
}
}
}
},
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "car"
}
}
}
},
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "car"
}
}
}
},
{
"statusMessageType": {
"MasterConsignment": {
"ReportedStatus": {
"ReasonCode": "ban"
}
}
}
}
];
$scope.opts = [];
angular.forEach($scope.res.fsus,function(key,value){
if(($scope.opts.indexOf(key.statusMessageType.MasterConsignment.ReportedStatus.ReasonCode , 0)) <= -1){ $scope.opts.push(key.statusMessageType.MasterConsignment.ReportedStatus.ReasonCode);
};
});
});<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.6/angular.min.js"></script>
<body ng-app="testApp" ng-controller="testCtrl">
<li ng-repeat="test in opts">
<span class="step"> {{test}}
</span>
</li>
