jQuery 在 ASP.Net 母版页中不工作
jQuery not working in ASP.Net master page
当我在普通 ASP.Net 页面中使用 jQuery DataTable 时,它工作正常。但是,当我在母版页中使用相同的相同代码时,它会给我一个错误:
Uncaught TypeError: $(...).prepend(...).dataTableExt is not a function
我正在写这两个代码是否有作品:

.cs 页面代码
using System;
using System.Data;
using System.Web.UI.WebControls;
namespace Citizen.WebApp.Login
{
public partial class MasterDataTable : System.Web.UI.Page
{
RegistrationBLL m_RegistrationBLL = new RegistrationBLL();
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = null;
dt = m_RegistrationBLL.GetList();

}
}
这样调用
$(function () {
$("table[id$='DataGridView']").prepend( $("<thead></thead>").append( $(this).find("tr:first") ) ).dataTable();
});
还要确保所有引用的 js 文件都存在。这意味着您不会在控制台中收到 404 错误。
其次,我建议将列呈现信息保留在 aspx 标记中,而不是将其保留在代码中。如下图:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowDataBound="OnRowDataBound">
<Columns>
<asp:BoundField DataField="Id" HeaderText="Customer Id" ItemStyle-Width="90" />
<asp:BoundField DataField="" HeaderText="Name" ItemStyle-Width="120" />
<asp:BoundField DataField="Country" HeaderText="Country" ItemStyle-Width="100" />
</Columns>
</asp:GridView>
不要使用预渲染事件,所有这些都可以通过标记来完成。所以尽可能地利用它。在代码中只需将数据集绑定到网格视图并调用数据绑定事件。
GridView1.DataSource = ds; // here assume ds is a dataset
GridView1.DataBind();
