AngularJS在同一元素上嵌套了ngRepeat

Question

Is there a way to perform nested loops in an AngularJS view without creating hidden dummy elements?

Something like this:

<ul>
    <li ng-repeat="gem in activeHero.gems"
        ng-repeat="(key, value) in gem.attributes"
        ng-repeat="attr in value">
            {{attr.text}}
    </li>
</ul>

or this

<ul>
    <li ng-repeat-start="gem in activeHero.gems"
        ng-repeat-start="(key, value) in gem.attributes"
        ng-repeat="attr in value">
            {{attr.text}}
    </li ng-repeat-end 
         ng-repeat-end>
</ul>

Neither of these is possible AFAIK.

I basically want my HTML to have a different structure than the JSON it's based on. How could I achive this? Is there a way to create loops inside a view without an HTML element?

The examples above would loop over a JSON structure like this:

JSON (stripped out a lot for clarity)

"activeHero" = {
  "gems" : [ {
    "attributes" : {
      "primary" : [ {
        "text" : "+220 Intelligence"
      } ],
      "secondary" : [ ],
      "passive" : [ ]
    }
  }, {
    "attributes" : {
      "primary" : [ {
        "text" : "+220 Intelligence"
      } ],
      "secondary" : [ ],
      "passive" : [ ]
    }
  }, {
    "attributes" : {
      "primary" : [ {
        "text" : "+160 Intelligence"
      } ],
      "secondary" : [ ],
      "passive" : [ ]
    }
  } ]
}

Answer 1

Try format your json before render;

$scope.formattedData = [];
angular.forEach(activeHero.gems, function(value, key){
      var item = {
         //set filed you want
      }
      angular.forEach(value.atrtibutes, function(value2, key2){
               item['propyouwant'] = value2[propyouwant]
               angular.forEach(value2.primary, function(value3, key3){
                      item['propyouwant'] = value3[propyouwant]
                     $scope.formattedData.push(angular.extend({}, item));
               })
      })
})

//now you can render your data without somersould

EDIT

For increasing performance and avoid to use angular extend;

$scope.formattedData = [];
angular.forEach(activeHero.gems, function(value, key){

      angular.forEach(value.atrtibutes, function(value2, key2){
               angular.forEach(value2.primary, function(value3, key3){
                     //start build your item here
                      var item = {
                        prop1: value['prop'],
                        prop2: value2['prop']
                       }
                     //not required extend item;
                     $scope.formattedData.push(item);
               })
      })
})
