<div>{{APIRef("WebGL")}}</div>
<p><strong><code>ebGLRenderingContext.bindBuffer()</code></strong> метод <a href="/en-US/docs/Web/API/WebGL_API">WebGL API</a> связывает {{domxref("WebGLBuffer")}} c точкой связывания(Атрибут регистром).</p>
<h2 id="Синтаксис">Синтаксис</h2>
<pre class="syntaxbox">void <var>gl</var>.bindBuffer(<var>target</var>, <var>buffer</var>);
</pre>
<h3 id="Параметры">Параметры</h3>
<dl>
<dt>target</dt>
<dd>{{domxref("GLenum")}} определяет точку связывания (target). Возможные значения:
<ul>
<li><code>gl.ARRAY_BUFFER</code>: Буфер содержащий вершинные атрибуты, такие как координаты, текстурные коориднаты(UV) или цвет вершины.</li>
<li><code>gl.ELEMENT_ARRAY_BUFFER</code>: Буфер использующий для индексирования элементов.</li>
<li>When using a {{domxref("WebGL2RenderingContext", "WebGL 2 context", "", 1)}}, the following values are available additionally:
<ul>
<li><code>gl.COPY_READ_BUFFER</code>: Buffer for copying from one buffer object to another.</li>
<li><code>gl.COPY_WRITE_BUFFER</code>: Buffer for copying from one buffer object to another.</li>
<li><code>gl.TRANSFORM_FEEDBACK_BUFFER</code>: Buffer for transform feedback operations.</li>
<li><code>gl.UNIFORM_BUFFER</code>: Buffer used for storing uniform blocks.</li>
<li><code>gl.PIXEL_PACK_BUFFER</code>: Buffer used for pixel transfer operations.</li>
<li><code>gl.PIXEL_UNPACK_BUFFER</code>: Buffer used for pixel transfer operations.</li>
</ul>
</li>
</ul>
</dd>
<dt>buffer</dt>
<dd>{{domxref("WebGLBuffer")}} с которым осуществляется связывание.</dd>
</dl>
<h3 id="Return_value">Return value</h3>
<p>Нет.</p>
<h3 id="Exceptions">Exceptions</h3>
<p>Only one target can be bound to a given {{domxref("WebGLBuffer")}}. An attempt to bind the buffer to another target will throw an <code>INVALID_OPERATION</code> error and the current buffer binding will remain the same.</p>

<pre class="brush: js">var canvas = document.getElementById('canvas');

var buffer = gl.createBuffer();
gl.bindBuffer(gl.ARRAY_BUFFER, buffer);
</pre>
<h3 id="Getting_current_bindings">Getting current bindings</h3>
<p>To check the current buffer bindings, query the <code>ARRAY_BUFFER_BINDING</code> and <code>ELEMENT_ARRAY_BUFFER_BINDING</code> constants.</p>

gl.getParameter(gl.ELEMENT_ARRAY_BUFFER_BINDING);
