<content:encoded><![CDATA[<h1 id="介绍"><a href="#介绍" class="headerlink" title="介绍"></a>介绍</h1><p>Cheat Engine是一款专注于游戏的修改器。它可以用来扫描游戏中的内存，并允许修改它们。它还附带了调试器、反汇编器、汇编器、变速器、作弊器生成、D3D hook工具、系统检查工具等。<br>但是，现在好多游戏都检测CE了，这对于我们找基址很不方便，这里给大家提供一下自己编译CheatEngine修改器的过程!</p><h1 id="第一步，准备工具及资源"><a href="#第一步，准备工具及资源" class="headerlink" title="第一步，准备工具及资源"></a>第一步，准备工具及资源</h1><p>github

<description><h1 id="前言"><a href="#前言" class="headerlink"</description>
<content:encoded><![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><span class="line">elem.id = 'haorooms'; </span><br><span class="line">elem.style = 'color: red'; </span><br><span class="line">elem.innerHTML = '我是新创建的haorooms测试节点'; </span><br><span class="line">document.body.appendChild(elem); </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");

方式绑定的都不会复制。</p><h2 id="createDocumentFragment"><a href="#createDocumentFragment" class="headerlink" title="createDocumentFragment"></a>createDocumentFragment</h2><p>本方法用来创建一个 DocumentFragment ，也就是文档碎片，它表示一种轻量级的文档，主要是用来存储临时节点，大量操作DOM时用它可以大大提升性能。</p><h1 id="节点修改API"><a href="#节点修改API" class="headerlink" title="节点修改API"></a>节点修改API</h1><ol><li><p>appendChild<br>语法：</p><blockquote><p>parent.appendChild(child);</p></blockquote></li><li><p>insertBefore</p><blockquote><p>parentNode.insertBefore(newNode, refNode);

<content:encoded><![CDATA[<h1 id="元素显示模式简介"><a href="#元素显示模式简介" class="headerlink" title="元素显示模式简介"></a>元素显示模式简介</h1><p>指元素（标签）以什么方式进行显示，比如<code><div></code>自己占一行，比如一行可以放多个<code><span></code>。<br>HTML元素一般分为<font color="red">块元素</font>和<font color="red">行内元素</font>。</p><h1 id="块元素"><a href="#块元素" class="headerlink" title="块元素"></a>块元素</h1><p>常见的块元素有： h1~h6, p, div, ul, ol, li 等，<code><div></code>是最典型的块元素。<br>块级元素特点：</p><ol><li>自己独占一行。</li><li>高度、宽度、外边距及内边距都可以控制。</li><li>宽度默认是容器（父元素）的100%。</li><li>是一个容器及盒子，里面可以放<font color="red">行内元素</font>和<font color="red">块级元素</font></li></ol><h1 id="行内元素"><a href="#行内元素" class="headerlink" title="行内元素"></a>行内元素</h1><p>常见的行内元素有： a, strrong, b, em, i, del, s, ins, u, span等，<code><span></code>是最典型的行内元素，也称<strong>内联元素</strong><br>行内元素的特点：</p><ol><li>相邻行内元素在一行上，一行可以显示多个。</li><li>高、宽直接设置无效。</li><li>默认宽度就是它本身内容的宽度。</li><li>行内元素只能容纳文本或其他行内元素。</li></ol><p><strong>注意</strong>：</p><ul><li>链接里面不能再放链接。</li><li>特殊情况链接<code><a></code>里面可以放块级元素，但是给<code><a></code>转换成块级显示模式最安全。</li></ul><h1 id="行内块元素"><a href="#行内块元素" class="headerlink" title="行内块元素"></a>行内块元素</h1><p>行内元素有几个特殊的标签<code><img /></code>、<code><input /></code>、<code><dt></code>，<font color=red>它们同时具有块元素和行内元素的特点</font>。</p><p>行内块元素特点：</p><ol><li>和相邻行内元素或行内块元素在一行上，但是它们之间会有空白间隙。一行可以显示多个（行内元素特点）。</li><li>默认宽度就是它本身内容的宽度（行内元素特点）。</li><li>高度、行高、外边距以及内边距都可以控制（块级元素特点）。</li></ol><h1
