javascript – TypeError：this.$E_0.getElementsByTagName不是函数

TypeError: this.$E_0.getElementsByTagName is not a function

var options = SP.UI.$create_DialogOptions();
options.html = '<div class="ExternalClass23FFBC76391C4EA5A86FC05D3D9A1904"><p>RedConnect is now available.​</p></div>';
options.width = 700;
options.height = 700;
SP.UI.ModalDialog.showModalDialog(options);

options.html需要HTML DOM元素而不是纯HTML代码：

<script>

  function ShowDialog()
  {
    var htmlElement = document.createElement('p');

    var HelloWorldNode = document.createTextNode('Hello world!');
    htmlElement.appendChild(HelloWorldNodE);

    var options = {
        html: htmlElement,autoSize:true,allowMaximize:true,title: 'Test dialog',showClose: true,};

    var dialog = SP.UI.ModalDialog.showModalDialog(options);
  }

</script>

<a href="javascript:ShowDialog()">Boo</a>

示例代码取自博客文章Rendering html in a SharePoint Dialog requires a DOM element and not a String.

当您查看文件SP.UI.Dialog.debug.js中SP.UI.DialogOptions“class”的定义时,您会看到它是一个空的javascript函数.

SP.UI.DialogOptions = function() {}
SP.UI.$create_DialogOptions = function() {ULSTYE:;
    return new SP.UI.DialogOptions();
}

我猜测它是出于客户诊断的目的.看看这个SO问题：What does this Javascript code do?
