## 语法

    dateObj.toDateString()

## 描述

`Date` 对象实例引用一个具体的时间点。调用 `toString` 方法会以美式英语和人类易读的形式返回日期对象的格式化字符串。在 SpiderMonkey 里，该字符串由日期部分（年月日）和其后的时间部分（时分秒及时区）组成。有时需要获取日期部分的字符串，这可以由 `toDateString` 方法完成。

The `toDateString` method is especially useful because compliant engines implementing ECMA-262 may differ in the string obtained from `toString` for `Date` objects, as the format is implementation-dependent and simple string slicing approaches may not produce consistent results across multiple engines.

## 例子

### 例子：`toDateString` 方法的简单使用

    var d = new Date(1993, 6, 28, 14, 39, 7);

    println(d.toString());     // prints Wed Jul 28 1993 14:39:07 GMT-0600 (PDT)
    println(d.toDateString()); // prints Wed Jul 28 1993
