示例1: split

/**
 * ECMA 15.5.4.14 String.prototype.split (separator, limit)
 *
 * @param self      self reference
 * @param separator separator for split
 * @param limit     limit for splits
 * @return array object in which splits have been placed
 */
@Function(attributes = Attribute.NOT_ENUMERABLE)
public static ScriptObject split(final Object self, final Object separator, final Object limit) {
    final String str = checkObjectToString(self);
    final long lim = limit == UNDEFINED ? JSType.MAX_UINT : JSType.toUint32(limit);

    if (separator == UNDEFINED) {
        return lim == 0 ? new NativeArray() : new NativeArray(new Object[]{str});
    }

    if (separator instanceof NativeRegExp) {
        return ((NativeRegExp) separator).split(str, lim);
    }

    // when separator is a string, it is treated as a literal search string to be used for splitting.
    return splitString(str, JSType.toString(separator), lim);
}
