类型错误：无法读取未定义的属性“childNodes”

I am trying to display a modal when the view is loaded.

我正在尝试在加载视图时显示模态。

Code :

代码：

//View
<div id="showCom" ng-controller="showmodalCtrl" ng-init="init()">

<div class="modal fade" id="companyModal" role="dialog">
 <div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
      <h4 class="modal-title">Please Select Company</h4>
    </div>
    <div class="modal-body">
     <form>
      <div class="form-group">
        <label class="control-label">Recipient:</label>
        <input type="text" class="form-control">
      </div>
     </form>
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-primary">Submit</button>
    </div>
  </div>
 </div>
</div>

//Controller
 .controller('showmodalCtrl', ['$scope', function($scope){

$scope.init = function(){
  $('#companyModal').modal("show");
}
 }])

Everything works fine and the modal is displayed but I get this error on the console :

一切正常，显示模态，但我在控制台上收到此错误：

Type error : Cannot read property 'childNodes' of undefined

I have no idea why this is happening. Also if I remove the "form" from the modal , i don't get any error. So I guess the problem is with the form but I am not able to resolve it.

我不知道为什么会这样。此外，如果我从模态中删除“表单”，我不会收到任何错误。所以我猜问题是表单，但我无法解决它。

Thanks in advance.

提前致谢。

5 个解决方案

#1

I had the same problem and I managed to resolve it by wrapping the modal open function inside a $timeout() or a normal setTimeout() function.

我遇到了同样的问题，我设法通过将模态打开函数包装在$ timeout（）或普通的setTimeout（）函数中来解决它。

setTimeout(function(){
   jQuery('#messageModal').modal('show');
}, 0);

I had the same error message when trying to use a JQuery plugin. Running it after document ready resolved the issue for me. The plugin was running fine but the angular code that followed in the current scope was not.

尝试使用JQuery插件时，我有相同的错误消息。文档就绪后运行它为我解决了问题。该插件运行正常，但当前范围中的角度代码不是。

It was the "Set timeout"-answer in this thread that led me to try this solution.

正是这个线程中的“设置超时” - 让我尝试了这个解决方案。

Solution for me:

我的解决方案：

angular.element(document).ready(function () {
    //Angular breaks if this is done earlier than document ready.
    setupSliderPlugin();
});

As another solution in AngularJS context I'm using this approach:

作为AngularJS上下文中的另一个解决方案，我正在使用这种方法：

1. Include $timeout module in your JS controller
2. 在JS控制器中包含$ timeout模块
3. Run init() function with all initializers like this:

   $timeout(init, 0);

   $ timeout（init，0）;

Works good.

效果很好。

Sorry for edit. Is your HTML well formed? Check that all the tags match.

抱歉编辑。你的HTML格式正确吗？检查所有标签是否匹配。

In your code snippet, it looks like you're missing a closing div. check that - the one that closes the controller div.

在您的代码段中，您似乎错过了结束div。检查 - 关闭控制器div的那个。

I had a similar problem. It would throw an exception when i tried to add some html to dom and compile it using $compile in angularJs.

我有类似的问题。当我试图将一些html添加到dom并使用angularJs中的$ compile编译它时会抛出异常。

Inside of the html was another directive that tried to add some dom element from the page to somewhere else in the page.

在html里面是另一个指令，试图将页面中的一些dom元素添加到页面中的其他位置。

I just had to call .clone of that element before i moved it to the new location. And the exception was gone.

在将其移动到新位置之前，我只需要调用该元素的.clone。异常消失了。

$popupContent = $(attrs.popupSelector).clone();
$container = $('<div class="popup-container"></div>');
$container.append($popupContent);
$container.hide();
$('body').append($container);
