<content type="html"><![CDATA[<h1 id="前言"><a href="#前言" class="headerlink" title="前言"></a>前言</h1><p>很多同学用惯了jquery操作dom，让他们用js操作的时候，常常力不从心，本文总结了常用的js的dom操作方法，供大家翻阅！其实说起js操作dom，我很久很久之前有篇文章，jquery属性的相关js实现方法,里面囊括了很大一部分js操作dom的常用方法，但是不是很系统。不能说是API，今天来系统总结一下！</p><h1 id="节点查找API"><a href="#节点查找API" class="headerlink" title="节点查找API"></a>节点查找API</h1><blockquote><p>document.getElementById ：根据ID查找元素，大小写敏感，如果有多个结果，只返回第一个；<br>document.getElementsByClassName ：根据类名查找元素，多个类名用空格分隔，返回一个 HTMLCollection 。注意兼容性为IE9+（含）。另外，不仅仅是> document，其它元素也支持 getElementsByClassName 方法；<br>document.getElementsByTagName ：根据标签查找元素， * 表示查询所有标签，返回一个 HTMLCollection 。<br>document.getElementsByName ：根据元素的name属性查找，返回一个 NodeList 。<br>document.querySelector ：返回单个Node，IE8+(含），如果匹配到多个结果，只返回第一个。<br>document.querySelectorAll ：返回一个 NodeList ，IE8+(含）。<br>document.forms ：获取当前页面所有form，返回一个 HTMLCollection ；</p></blockquote><h1 id="节点创建API"><a href="#节点创建API" class="headerlink" title="节点创建API"></a>节点创建API</h1><h2 id="createElement创建元素："><a href="#createElement创建元素：" class="headerlink" title="createElement创建元素："></a>createElement创建元素：</h2><figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">var elem = document.createElement("div");

</span><br></pre></td></tr></table></figure><p>通过 createElement 创建的元素并不属于 document 对象，它只是创建出来，并未添加到html文档中，要调用 appendChild 或 insertBefore 等方法将其添加到HTML文档中。</p><h2 id="createTextNode创建文本节点："><a href="#createTextNode创建文本节点：" class="headerlink" title="createTextNode创建文本节点："></a>createTextNode创建文本节点：</h2><figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">var node = document.createTextNode("我是文本节点");
