使用js实现HTML静态页面表格数据分页(表头保持不变)

这是最终实现的效果图

下面是Html代码

<table id="pageListTable">
	<thead>
		<tr>
			<th style="text-align: center;">...</th>
			<th style="text-align: center;">...</th>
			<th style="text-align: center;">...</th>
			<th style="text-align: center;">...</th>
		</tr>
		<tr>
			<th style="text-align: center;">...</th>
			<th style="text-align: center;">...</th>
			<th style="text-align: center;">...</th>
			<th style="text-align: center;">...</th>
		</tr>
		<tr>
			<th style="text-align: center;">...</th>
			<th style="text-align: center;">...</th>
			<th style="text-align: center;">...</th>
			<th style="text-align: center;">...</th>
		</tr>
	</thead>
	<tbody id="pageListTableBody">
		<tr>
			<td style="text-align: center;">...</td>
			<td style="text-align: center;">...</td>
			<td style="text-align: center;">...</td>
			<td style="text-align: center;">...</td>
		</tr>
		<tr>
			<td style="text-align: center;">...</td>
			<td style="text-align: center;">...</td>
			<td style="text-align: center;">...</td>
			<td style="text-align: center;">...</td>
		</tr>
		<tr>
			<td style="text-align: center;">...</td>
			<td style="text-align: center;">...</td>
			<td style="text-align: center;">...</td>
			<td style="text-align: center;">...</td>
		</tr>
	</tbody>
</table>
<div id="pages" style="float: right;">
   <span id="spanFirst">首页</span>
    <span id="spanPre">上一页</span>
    <span id="spanNext">下一页</span>
    <span id="spanLast">尾页</span>
    第<strong id="spanPageNum"></strong>页/共
    <strong id="spanTotalPage"></strong>页 </div>
</div>

下面是js代码块

	var theUL = document.getElementById("pageListTableBody");
    var totalPage = document.getElementById("spanTotalPage");
    var pageNum = document.getElementById("spanPageNum"); //获取当前页<span>
    var spanPre = document.getElementById("spanPre"); //获取上一页<span>
    var spanNext = document.getElementById("spanNext"); //获取下一页<span>
    var spanFirst = document.getElementById("spanFirst"); //获取第一页<span>
    var spanLast = document.getElementById("spanLast"); //获取最后一页<span>
    var numberRowsInTable = theUL.getElementsByTagName("tr").length; //记录总条数
    var pageSize = 10; //每页显示的记录条数
    var page = 1; //当前页，默认第一页

    //下一页
    function next(){
        hideTable();
        currentRow = pageSize * page;
        maxRow = currentRow + pageSize;
        if ( maxRow > numberRowsInTable ) maxRow = numberRowsInTable;
        for ( var i = currentRow; i< maxRow; i++ ){
            theUL.getElementsByTagName("tr")[i].style.display = '';
        }
        page++;
        if ( maxRow == numberRowsInTable ) {
            nextText();
            lastText();
        }
        showPage();
        preLink();

        }
    }

    function showPage(){
        pageNum.innerHTML = page;
    }

    //总共页数

    }
    //显示链接

    }
    function preText(){
        spanPre.innerHTML = "上一页";
    }
