Angularjs根据服务器响应更改复选框值

Question

我有两组复选框，用户可以在其中选择他们的选项并将其作为字符串保存到数据库中。

是否可以从服务器获取此字符串响应并将每个值设置回相应的复选框以保持选中状态？

<form class="list">

    <ion-toggle toggle-class="toggle-balanced" ng-model="data.turnOnOff" ng-true-value="'On'" ng-false-value="'Off'" ng-change="data.showConfirm(data.turnOnOff)">Databases</ion-toggle>
    <div class="spacer" style="height: 10px;"></div>

    <ion-list ng-show="bd">
        <ion-checkbox ng-repeat="(key, value) in db" ng-model=value.checked ng-change="checka()">{{ value.text }}</ion-checkbox>
    </ion-list>
    <div class="spacer" style="height: 10px;"></div>


    <ion-toggle toggle-class="toggle-balanced" ng-model="data.escritorio" ng-true-value="'On'" ng-false-value="'Off'" ng-change="data.openEscritorio(data.escritorio)">Office</ion-toggle>
    <div class="spacer" style="height: 10px;"></div>

    <ion-list ng-show="officee">
        <ion-checkbox ng-repeat="(key, value) in office" ng-model=value.checked>{{ value.text }}</ion-checkbox>
    </ion-list>
    <div class="spacer" style="height: 10px;"></div>
</form>
<div class="spacer" style="height: 10px;"></div>
<button style="color:#FFFFFF;" class="button button-balanced button-block" ng-click="insert()">Ok</button>

var id = localStorage.getItem("id");
var checkedData = [];

    {text:'Firebird', checked:'false'},

    if(val === 'On'){
        $scope.officee = true;
    }else{
        $scope.officee = false;
    }
}

$scope.insert = function(){

    $ionicLoading.show({
        content: 'Loading',
        animation: 'fade-in',
        showBackdrop: true,
        maxWidth: 200,
        showDelay: 0
    });

    angular.forEach($scope.db, function(key, value){
        if(key.checked == true){
            //checkedData.push(key.text);
            checkedData += key.text + ', ';
            console.log("database "+checkedData);
        }
    });

    angular.forEach($scope.office, function(key, value){
        if(key.checked == true){
            checkedData += key.text + ', ';
            console.log("databases "+checkedData);   
        }
    });

    checkedData = checkedData.substring(0, checkedData.length - 2);
    console.log("result: "+checkedData);

    InformaticaFac.getData(checkedData, id).then(function(response){

        console.log(JSON.stringify(response));

        if(response.data === "\"Error\""){
            $ionicLoading.hide();
            navigator.notification.alert("Error");

        }else{

            checkedData = response.data[0].DATABASERESP;

        }
    }, function(response){
            navigator.notification.alert("Error.");

    }).finally(function(){
        $timeout(function(){

            $ionicLoading.hide();                
            $state.go('page3');

        }, 2000); 
    });

}

回复

checkedData = response.data[0].DATABASERESP;

"data":{"checkedData":"Firebird, MySQL, Oracle, Microsoft Excel, Microsoft Outlook, Microsoft PowerPoint, Microsoft Word","id":"1"}

Answer 1

我明白了，所以你可以试试这个：

  var checkedData = response.data

  checkedData.checkedData.forEach(function(checkedName) {

      $scope.db.forEach(function(dbItem){

          if(dbItem.text == checkedName) {
                dbItem.checked = true;
          }

      })

      $scope.office.forEach(function(officeItem){

          if(officeItem.text == checkedName) {
                officeItem.checked = true;
          }

      })

  })

  // if you do it in .then(function) or any async function you need to call
  $scope.$apply() // to update checkboxes state

更新

您忘记将字符串拆分为数组：

   checkedData.data.checkedData = checkedData.data.checkedData.split(', ');

所以现在我们可以做.forEach函数

Answer 2

我不得不做出一些改变，但根据 Leguest 的回答，我的最终结果是：

checkedData= response.data[0].DATABASERESP;
console.log(checkedData);

checkedData = checkedData.split(', ');
console.log(checkedData);

angular.forEach(checkedData, function(checkedName){

    $scope.db.forEach(function(dbItem){

        if(dbItem.text == checkedName) {
            dbItem.checked = true;
        }

   });

   $scope.office.forEach(function(officeItem){

       if(officeItem.text == checkedName) {
            officeItem.checked = true;
       }

   });

});
