<p><a href="/en-US/docs/Web/API/WebGL_API">WebGL API</a> 的 <strong><code>WebGLRenderingContext.bindRenderbuffer()</code></strong> 方法将给定的 {{domxref("WebGLRenderbuffer")}} 绑定到一个目标，它必须是 gl.RENDERBUFFER 。</p>
<h2 id="语法">语法</h2>
<pre class="syntaxbox">void <var>gl</var>.bindRenderbuffer(<var>target</var>, <var>renderbuffer</var>);
</pre>
<h3 id="参数">参数</h3>
<dl>
<dt>target</dt>
<dd>{{domxref("GLenum")}} 指定绑定点（目标）。 可能的值：
<ul>
<li><code>gl.RENDERBUFFER</code>: 以可渲染的内部格式对单个图像进行缓冲数据存储。</li>
</ul>
</dd>
<dt>renderbuffer</dt>
<dd>要绑定的 {{domxref("WebGLRenderbuffer")}} 对象。</dd>

<p>None.</p>
<h3 id="抛出错误">抛出错误</h3>
<p>如果 <code>target</code> 不是 <code>gl.RENDERBUFFER</code>，则抛出 <code>gl.INVALID_ENUM </code>错误。</p>
