IE9 IE 10 IE11 createNodeIterator - ＆＃34;发生异常。＆＃34;

Question

我正在使用createNodeIterator查找文档中的单词。

实际上我几乎使用了来自MDN和MSDN的确切示例代码：

• https://developer.mozilla.org/en-US/docs/Web/API/Document/createNodeIterator
• https://msdn.microsoft.com/en-us/library/ff975301(v=vs.85).aspx

这在Chrome和Firefox中正常运行 不幸的是，Internet Explorer 11只是说Exception occurred.并在我致电iterator.nextNode

后停止

Codepen：https://codepen.io/anon/pen/PKmQEe?editors=1011

代码示例：

＆＃13;

＆＃13;

var iterator = document.createNodeIterator(document.body, NodeFilter.SHOW_TEXT, {
  acceptNode: function acceptNode(node) {
    if (node.parentNode.tagName.toLowerCase() === 'span') {
      return NodeFilter.FILTER_REJECT;
    }

    return NodeFilter.FILTER_ACCEPT;
  }
}, false);

var nextNode = void 0;
var nodes = [];
while (nextNode = iterator.nextNode()) {
  if (nextNode.nodeValue.indexOf('o') > -1) {
    nodes.push(nextNode);
  }
}

console.log(nodes.length);
nodes.forEach(function (node) {
  return node.nodeValue = node.nodeValue.replace('o', 'OO');
});
