+
+<p>{{jsxref("Date")}}对象覆盖了 {{jsxref("Object")}} 对象的 <code>toString() </code>方法；它不是继承自 {{jsxref("Object.prototype.toString()")}}。对于  {{jsxref("Date")}} 对象，<code>toString()</code> 方法返回一个表示该对象的字符串。</p>
+
+<p>该 <code>toString</code> 方法总是返回一个美式英语日期格式的字符串。</p>
+
+<p>当一个日期对象被用来作为文本值或用来进行字符串连接时，<code>toString</code> 方法会被自动调用。</p>
+
+<p><code>toString() </code>是通用函数。如果不是{{jsxref("Date")}}实例，则 返回"Invalid Date"。</p>
