有时候,在线Web开发时,需要显示的数据往往会超过我们规定的表格长度,所以为了方便显示大量数据,为了美观,这里提出了两种显示数据方式。
①可以滚动显示数据但是表头未能获取
效果显示
前端DEMO
<span style="font-family:Microsoft YaHei;font-size:18px;"><body>
<form id="form1" runat="server">
<div id="headdiv" style="top: 16px; text-align:center; left: 152px; position: absolute; width: 629px;height: 21px;word-wrap:break-word; overflow:hidden;"><!--不需要显示表头水平滚动条-->
</div>
<div id="bodydiv" style="top: 33px; left: 152px; position: absolute; width: 647px;height: 300px; overflow: auto" onscroll="headdiv.scrollLeft=scrollLeft"><!--表体的水平滚动条拖动触发表头的水平滚动事件-->
<!--Gridview中必须定义表头和表体相同的宽度-->
<asp:GridView ID="GridView1" BorderColor="Black" OnRowDataBound="GridView1_RowDataBound" runat="server" AutoGenerateColumns="False" Font-Size="12px" width="629px">
<Columns>
<asp:BoundField DataField="ID" HeaderText="编号" >
<HeaderStyle Width="40px" />
<ItemStyle Width="40px" />
</asp:BoundField>
<asp:BoundField DataField="EmpID" HeaderText="账号" >
<HeaderStyle Width="70px" />
<ItemStyle Width="70px" />
</asp:BoundField>
<asp:BoundField DataField="EmpRealName" HeaderText="姓名" >
<HeaderStyle Width="60px" />
<ItemStyle Width="60px" />
</asp:BoundField>
<asp:BoundField DataField="EmpSex" HeaderText="性别" >
<HeaderStyle Width="40px" />
<ItemStyle Width="40px" />
</asp:BoundField>
<asp:BoundField DataField="EmpAddress" HeaderText="住址" >
<HeaderStyle Width="140px" />
<ItemStyle Width="140px" />
</asp:BoundField>
<asp:BoundField DataField="EmpZipCode" HeaderText="邮编" >
<HeaderStyle Width="40px" />
<ItemStyle Width="40px" />
</asp:BoundField>
<asp:BoundField DataField="EmpBirthday" HeaderText="生日" DataFormatString="{0:d}" HtmlEncode="False" >
<HeaderStyle Width="120px" />
<ItemStyle Width="120px" />
</asp:BoundField>
<asp:BoundField DataField="EmpSalary" HeaderText="月薪" >
<HeaderStyle Width="40px" />
<ItemStyle Width="40px" />
</asp:BoundField>
</Columns>
<RowStyle HorizontalAlign="Center" />
<PagerStyle HorizontalAlign="Center" />
<HeaderStyle BackColor="Azure" Font-Bold="True" ForeColor="Black" CssClass="Freezing" Font-Size="12px" HorizontalAlign="Center"/>
</asp:GridView>
</div>
</form>
</body></span>
②可以滚动显示数据表头一直存在
效果显示
改善部分,在前者基础上增加了JavaScript方法
DEMO
<span style="font-family:Microsoft YaHei;font-size:18px;"> <script language="javascript" type="text/javascript">
function init()
{
var bodyGridView=document.getElementById("<%=GridView1.ClientID%>");
var headGridView=bodyGridView.cloneNode(true);
for(i=headGridView.rows.length-1;i>0;i--)
headGridView.deleteRow(i);
bodyGridView.deleteRow(0);//删掉数据行
headdiv.appendChild(headGridView);//删掉表头行
}
window.onload=init;
</script></span>
