title: Date.prototype.setFullYear()
slug: Web/JavaScript/Reference/Global_Objects/Date/setFullYear
translation_of: Web/JavaScript/Reference/Global_Objects/Date/setFullYear
---
<div>{{JSRef("Global_Objects", "Date")}}</div>
<p><code><strong>setFullYear()</strong></code> 方法根据本地时间为一个日期对象设置年份。</p>
<div>{{EmbedInteractiveExample("pages/js/date-setfullyear.html")}}</div>
<h2 id="Syntax" name="Syntax">语法</h2>
<pre class="syntaxbox language-html" style="margin-bottom: 0px; padding: 1em; border-left-width: 6px; border-left-style: solid; font-family: Consolas, Monaco, 'Andale Mono', monospace; font-size: 14px; text-shadow: none; direction: ltr; white-space: normal; background-color: rgba(212, 221, 228, 0.498039);"><code class="language-html" style="font-family: Consolas, Monaco, 'Andale Mono', monospace; color: inherit; text-shadow: none; direction: ltr;">dateObj.setFullYear(yearValue[, monthValue[, dayValue]])</code></pre>
<h3 id="Parameters" name="Parameters">参数</h3>
<dl>
<dt><code>yearValue</code></dt>
<dd>指定年份的整数值，例如1995。</dd>
<dt><code>monthValue</code></dt>
<dd>一个0到11之间的整数值，表示从一月到十二月。</dd>
<dt><code>dayValue</code></dt>
<dd>一个1到31之间的整数值，表示月份中的第几天。如果你指定了 <code>dayValue</code> 参数，就必须同时指定 <code>monthValue</code>。</dd>
</dl>
<h2 id="Description" name="Description">描述</h2>
<p>如果没有指定 <code>monthValue</code> 和<code>dayValue</code> 参数，将会使用 <code>getMonth</code> 和<code>getDate</code> 方法的返回值。</p>
<p>如果有一个参数超出了合理的范围，<code>setFullYear</code> 方法会更新其他参数值，日期对象的日期值也会被相应更新。 例如，为 <code>monthValue </code>指定 15， 则年份会加1，月份值会为3。</p>
