【问题描述】：
我正在构建我的第一个 AngularJS 动态表单，它基于使用 AngularJS 指令从 JSON 文件接收到的信息构建。
一切正常，我的问题是在加载页面时会显示 JSON 代码 - 一旦加载页面，JSON 代码就会消失。
我做错了吗？
检查http://plnkr.co/edit/v4jOwuF6jmZfORlNbvIB?p=preview查看行为，点击“停止”/“开始”多次查看行为。
HTML 代码：
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script data-require="angular.js@*" data-semver="1.4.0-beta.2" src="https://code.angularjs.org/1.4.0-beta.2/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="ViewCtrl">
<div ng-repeat="page in form.form_pages">
<div ng-repeat="field in page.page_fields" class="form-group">
<field-directive field="field" ng-form="subForm"></field-directive>
</div>
</div>
</body>
js代码：
'use strict';
angular.module('myApp',[])
.controller('ViewCtrl', ['$scope', function($scope) {
var jsonStr='{"form_id":"1","form_name":"My Test Form","form_pages":{"1":{"page_id":1,"page_title":"My First Tab","page_hide":false,"page_fields":{"1":{"field_id":1,"field_title":"First Name","field_type":"textfield","field_value":"","field_required":true,"field_disabled":false},"2":{"field_id":2,"field_title":"Last Name","field_type":"textfield","field_value":"","field_required":true,"field_disabled":false},"3":{"field_id":3,"field_title":"Gender","field_type":"textfield","field_value":"0","field_required":true,"field_disabled":false},"4":{"field_id":4,"field_title":"Email Address","field_type":"textfield","field_value":"","field_required":true,"field_disabled":false},"5":{"field_id":5,"field_title":"Password","field_type":"textfield","field_value":"","field_required":true,"field_disabled":false},"6":{"field_id":6,"field_title":"Birth Date","field_type":"textfield","field_value":"1981-01-10T06:00:00.000Z","field_required":true,"field_disabled":false},"7":{"field_id":7,"field_title":"Your browser","field_type":"textfield","field_value":"2","field_required":false,"field_disabled":false},"8":{"field_id":8,"field_title":"Additional Comments","field_type":"textarea","field_value":"","field_required":true,"field_disabled":false},"9":{"field_id":9,"field_title":"I accept the terms and conditions.","field_type":"textfield","field_value":"0","field_required":true,"field_disabled":false}}}}}';
$scope.form = JSON.parse(jsonStr);
}])
.directive('fieldDirective',function($http, $compile) {
var linker = function(scope, element) {
// GET template content from path
var templateUrl = "textfield.html";
$http.get(templateUrl).success(function(data) {
element.html(data);
$compile(element.contents())(scope);
});
}
return {
template: '<div>{{field}}</div>',
restrict: 'E',
scope: {
field: '='
},
link: linker
};
})
textfield.html - html 模板：
<div class="row" ng-form="subForm" ng-class="{'has-success': subForm[field.field_id].$invalid}">
<div class="col-sm-5">{{field.field_title}}:</div>
<div class="col-sm-7">
<input type="text"
placeholder="{{field.field_title}}"
ng-model="field.field_value"
value="{{field.field_value}}"
ng-required="field.field_required"
ng-disabled="field.field_disabled"
class="form-control"
id = "{{field.field_id}}"
name = "{{field.field_id}}" >
<div ng-show="subForm[field.field_id].$touched && subForm[field.field_id].$error && subForm[field.field_id].$invalid">Field '{{field.field_title}}'
<span ng-show="subForm[field.field_id].$error.required"> is required.</span>
</div>
</div>
</div>
谢谢。

欢迎来到 SO。请在问题本身中发布代码的 相关 部分 - 不要依赖外部链接（尽管有指向 plunker 的链接 - 作为附加参考 - 总是好的）。这是ask a question 的最佳途径的一个很好的指南

无法完全阐述原因，认为这是向 dom 添加东西的循环，有角度应用它的绑定等，但您可以通过更改链接方式来防止问题（模板：'',)

感谢@MarvinSmit 这是解决方案。
