Question

你能告诉我如何在angulat.js中动态创建列表。当我用户按下添加按钮并填写字段时，我能够制作列表。换句话说，无论何时填写生成一行的字段，请检查此小提琴。当您点击该行时，您可以获得ID。http://jsfiddle.net/wc4Jm/6/ 现在我尝试使用bootstrap模型来实现这一点。换句话说，首先按钮点击我会显示一个弹出屏幕，然后有＆＃34;添加＆＃34;按钮.on点击它生成行。但我得到＆＃34;未定义＆＃34;。我在控制器中插入模型div？这是 http://jsbin.com/vubojoxo/4/

为什么我收到此错误？ XMLHttpRequest无法加载file：/// C：/Users/asd/Desktop/angular/angularproject/dialog.html。收到无效回复。起源＆＃39; null＆＃39;因此不允许访问。

当我使用plunker时，我收到此错误..并在我的桌面上运行.. 我做这个HTML？

<!doctype html>
<html ng-app="plunker">
<head>
    <script src="angular.js"></script>
    <script src="ui-bootstrap-tpls-0.2.0.js"></script>
    <link href="bootstrap-combined.min.css" rel="stylesheet">

    <script src="index.js"></script>

</head>
<body>

<div ng-controller="DialogDemoCtrl">
    <a class="btn" data-toggle="modal" href="" ng-click="openPopupScreen()">Add Contend</a>
</div>

</body>
</html>

.... Dialog.html

<div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h1>Add Element</h1>
</div>
<div class="modal-body">
    <form >
        <label>Name:</label><input type="text" class="span3" ng-model="activeItem.name"></br>
        <label>Content Name:</label><input type="password" class="span3" ng-model="activeItem.content"></br>
        <button type="submit" class="btn btn-success" ng-click="addItem()">Add In List</button>
        <button type="reset" class="btn ">Clear</button>
    </form>
</div>
<div class="modal-footer">
    <a class="btn" data-dismiss="modal" aria-hidden="true">close</a>
</div>

js code：

var myApp = angular.module('plunker', ['ui.bootstrap']);

myApp.controller('DialogDemoCtrl',  function($scope,$dialog) {
    $scope.items = [];
    $scope.activeItem = {
        id:'',
        name: '',
        content: ''
    };

    $scope.addItem = function () {
        $scope.activeItem.id = $scope.items.length + 1;
        $scope.items.push($scope.activeItem);
        $scope.activeItem = {}; /* reset active item*/

    };

    $scope.getId = function (item) {
        alert('ID: '+item.id);

    };
    $scope.openPopupScreen = function () {
        alert('Check Open pop up screen');
        $dialog.dialog({}).open('dialog.html');

    };

});

检查此 Plunker

在这个例子中，我使用了angular-ui库，它将bootstrap的模态包装成angular based on this StackOverflow Answer

<强> ModalDemoCtrl

  $scope.items = [];

  $scope.getId = function(item) {
    alert('ID: ' + item.id);

  };

  // This opens a Bootstrap modal
  $scope.open = function() {

    var modalInstance = $modal.open({
      template: $scope.modal_html_template,
      controller: ModalInstanceCtrl
    });

    modalInstance.result.then(function(newItem) {
      // On modal success

      newItem.id = $scope.items.length + 1;

      $scope.items.push(newItem);

    }, function() {
      // On modal cancelation
    });
  }

<强> ModalInstanceCtrl

  $scope.name = '';
  $scope.content = '';

  $scope.ok = function() {

    var response = {
      'name': $scope.name,
      'content': $scope.content
    };

    $modalInstance.close(response);

  };

  $scope.cancel = function() {
    $modalInstance.dismiss('cancel');
  };

<强> HTML
