Question

我有一个动态的角度形式。我想以json的身份发送回复。如何从表单生成JSON？

这里是完整的代码，我必须得到json，并将其发布到某个api。

    <!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>

<div ng-app="myApp" ng-controller="dyf" ng-submit="submit()"> 

<form name="userFormOne" novalidate>
    <table>
      <tr class="form-group" ng-repeat="x in names">

        <td><label>{{ x.Field }}</label>
        </td><td><input type="text" class="form-control" placeholder="{{x.Comment}}" required>
        </td>
      </tr>
     </table>{{data}}
    </form>

</div>

<script>
var app = angular.module('myApp', []);
app.controller('dyf', function($scope, $http) {
    $http.get("http://localhost:5000/gu")
    .then(function (response) {$scope.names = response.data;console.log(response.data);});

    $scope.data ={};



});


</script>

</body>
</html>

在 AngularJs 中，我们使用 ng-model 将输入值绑定到我们的控制器示例：

这个完整的示例来说明如何从数组创建一个简单的表单以及如何将它作为JSON发送到您的API。

注意：在提交时检查您的控制台，并查看对象值。

.directive('planText', function(){
      return {
        restrict:'E',
        templateUrl: 'app/partials/planText.html',
        link: function(scope, element, attrs){

          element.find("ul").bind('keydown', function(event){
            console.log("keydown event");
          if (event.keyCode == 8) {
            // console.log("backspace pressed");
            if ($(this).children().length == 1 && $(this).children("li").text().split("").length == 0) {
                console.log("stop li removal");
                event.preventDefault();
            }
          }
        });
        element.find("ul").bind('focus', function(event){
            if ($(this).children().length ==0 ) {
                console.log("insert li");
                $(this).append("<li></li>");
            }
        });
        }
      }
})
