NonDocumentTypeChildNode.nextElementSibling - Web APIs 编辑

The NonDocumentTypeChildNode.nextElementSibling read-only property returns the element immediately following the specified one in its parent's children list, or null if the specified element is the last one in the list.

Syntax

var nextNode = elementNodeReference.nextElementSibling; 

Example

<div id="div-01">Here is div-01</div>
<div id="div-02">Here is div-02</div>

<script type="text/javascript">
  var el = document.getElementById('div-01').nextElementSibling;
  console.log('Siblings of div-01:');
  while (el) {
    console.log(el.nodeName);
    el = el.nextElementSibling;
  }
</script>

This example outputs the following into the console when it loads:

Siblings of div-01:

Polyfill for Internet Explorer 8

This property is unsupported prior to IE9, so the following snippet can be used to add support to IE8:

// Source: https://github.com/Alhadis/Snippets/blob/master/js/polyfills/IE8-child-elements.js
if(!("nextElementSibling" in document.documentElement)){
    Object.defineProperty(Element.prototype, "nextElementSibling", {
        get: function(){
            var e = this.nextSibling;
            while(e && 1 !== e.nodeType)
                e = e.nextSibling;
            return e;
        }
    });
}

Polyfill for Internet Explorer 9+ and Safari

// Source: https://github.com/jserz/js_piece/blob/master/DOM/NonDocumentTypeChildNode/nextElementSibling/nextElementSibling.md
(function (arr) {
  arr.forEach(function (item) {
    if (item.hasOwnProperty('nextElementSibling')) {
      return;
    }
    Object.defineProperty(item, 'nextElementSibling', {
      configurable: true,
      enumerable: true,
      get: function () {
        var el = this;
        while (el = el.nextSibling) {
          if (el.nodeType === 1) {
              return el;
          }
        }
        return null;
      },
      set: undefined
    });
  });
})([Element.prototype, CharacterData.prototype]);
