来自json数据的AngularJS动态表单（不同类型）

Question

我尝试使用JSON中的数据在AngularJS中创建动态表单。我有这个工作：

HTML

    <p ng-repeat="field in formFields">
            <input 
                dynamic-name="field.name"
                type="{{ field.type }}"
                placeholder="{{ field.name }}"
                ng-model="field.value"
                required
            >
            <span ng-show="myForm.{{field.name}}.$dirty && myForm.{{field.name}}.$error.required">Required!</span>
            <span ng-show="myForm.{{field.name}}.$dirty && myForm.{{field.name}}.$error.email">Not email!</span>
    </p>
    <button ng-disabled="myForm.$invalid">Submit</button>                 
</form>

JS

angular.module('angularTestingApp').controller('DynamicFormCtrl', function ($scope) {

$scope.formFields = [
    {
        name: 'firstName',
        type: 'text'
    },
    {
        name: 'email',
        type: 'email'
    },
    {
        name: 'password',
        type: 'password'
    },
    {
        name: 'secondName',
        type: 'text'
    }
];}).directive("dynamicName",function($compile){
return {
    restrict:"A",
    terminal:true,
    priority:1000,
    link:function(scope,element,attrs){
        element.attr('name', scope.$eval(attrs.dynamicName));
        element.removeAttr("dynamic-name");
        $compile(element)(scope);
    }
}});

这段代码有效，但是问题是 我不知道如何添加动态复选框或清单 以及如何在表单内部进行 验证 ，如下所示：

angular.module('angularTestingApp')

.controller（’DynamicFormCtrl’，function（$ scope）{

$scope.formFields = [
    {
        name: 'firstName',
        type: 'text'
    },
    {
        name: 'email',
        type: 'email'
    },
    {
        name: 'password',
        type: 'password'
    },
    {
        name: 'city',
        type: 'checkbox',
        choices: [
            { name: "red" },
            { name: "blue" },
            { name: "green" },
        ]
    }
];})

预先感谢您的关注。最好的祝福！
