    fields: [
          {field1: value1},

推荐答案

NG-模型会为你。如果您尚未创建自己成为一个变量的范围将创建

ng-model does it for you. A scope variable will be created if you haven't already created it yourself

<form name="myForm" ng-submit="submitMyForm()">
    <input ng-model="fields.name"  />

function myController($scope){
    $scope.submitMyForm=function(){
        /* while compiling form , angular created this object*/
        var data=$scope.fields;  
        /* post to server*/
        $http.post(url, data);        
    }

}

如果你要开始在你的范围的角度将在2路绑定到输入端的对象，这样在范围对象最初设置的任何值将在输入显示

If you have the object to start with in your scope angular will 2 way bind to the input, so any values that are initially set in the scope object will show up in the input
