这是我的下拉绑定代码

This is my dropdown bind code

public void FillDropDownList()
    {
        s = WebConfigurationManager.ConnectionStrings["Scon"].ConnectionString;
        con = new SqlConnection(s);
        con.Open();
        cmd = new SqlCommand("select AUDITNAME from MASTER ", con);
        dr = cmd.ExecuteReader();
        while (dr.Read())
        {
            ddauditlist.Items.Add(new ListItem(dr["AUDITNAME"].ToString()));
        }            
        dr.Close();
        con.Close();
    }

尝试：

<script type="text/javascript">
function pageLoad() {
