页面分页关键点

	/** 总记录 */
	protected int recordCount = 0;

	/** 页数 */
	protected int currPage = 1;

	/** 页面大小 */
	protected int pageSize = 10;

	/** 总页数 */
	protected int pageCount = 0;

	/** 起始记录 */
	protected int startRecord = 0;

	/**
	 * 功能：计算分页显示，所取数据。
	 */
	public void account() {

		// 计算总页�数
		if (recordCount % pageSize == 0) {
			this.pageCount = this.recordCount / pageSize;
		} else {
			this.pageCount = this.recordCount / pageSize + 1;
		}

		// 判断页数是否超出范围
		if (currPage < 1) {
			this.currPage = 1;
		}

		if ((pageCount != 0) && (currPage > pageCount)) {
			this.currPage = pageCount;
		}

		// 设置起始记录
		this.startRecord = pageSize * (currPage - 1);
