AngularJS:ng-repeat中的ng-model？

Question

我正在尝试使用ng-repeat生成表单输入.注意:'customFields'是一个字段名称数组:["Age","Weight","Ethnicity"].

 <div class="control-group" ng-repeat="field in customFields">
   <label class="control-label">{{field}}</label>
     <div class="controls">
       <input type="text" ng-model="person.customfields.{{field}}" />
     </div>
 </div>

设置'ng-model'的最佳/正确方法是什么？我想将它作为person.customfields.'fieldname'发送到服务器,其中fieldname来自"customFields中的字段".

Answer 1

<div ng-app ng-controller="Ctrl">
    <div class="control-group" ng-repeat="field in customFields">
        <label class="control-label">{{field}}</label>
        <div class="controls">
            <input type="text" ng-model="person.customfields[field]" />
        </div>
    </div>
    <button ng-click="collectData()">Collect</button>
</div>

function Ctrl($scope) {
    $scope.customFields = ["Age", "Weight", "Ethnicity"];
    $scope.person = {
        customfields: {
            "Age": 0,
                "Weight": 0,
                "Ethnicity": 0
        }
    };

    $scope.collectData = function () {
        console.log($scope.person.customfields);
    }
}

你可以在这里试试.

更新:

对于验证,诀窍是放入<ng-form>转发器.请试试.

它应该是:

<input type="text" ng-model="person.customfields[field]" />
