我有一个无效的方法ProcessRequest
public void ProcessRequest(HttpContext context)
{
string term = context.Request["term"] ?? "";
List<string> listAddress = new List<string>();
string cs = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
using (SqlConnection con = new SqlConnection(cs))
{
SqlCommand cmd = new SqlCommand("spGetAddressByindex", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter()
{
ParameterName = "@term",
Value = term
});
con.Open();
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
listAddress.Add(rdr["Address"].ToString());
}
}
JavaScriptSerializer js = new JavaScriptSerializer();
context.Response.Write(js.Serialize(listAddress));
}
此方法只能通过其类PickupHandler.ashx.cs在我的AddressDate.html Javascript中进行调用
<script src="Scripts/jquery-3.3.1.js"></script>
<link href="Scripts/jquery-ui.css" rel="stylesheet" />
<script src="Scripts/jquery-ui.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#textbox').autocomplete({
source: 'PickupHandler.ashx'
});
});
</script>
</head>
<body>
<input type="text" id="textbox"/>
</body>
</html>
现在，我的Pickuphandler.ashx类中有一个名为ProcessRequest2的新方法，该如何在相同的JavaScript源代码中调用它？甚至有可能还是我应该仅将其保留在一种方法中，但似乎那样会使它变得困难？
public void ProcessRequest2(HttpContext context)
{
string term = context.Request["term"] ?? "";
List<string> listAddress = new List<string>();
string cs = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
using (SqlConnection con = new SqlConnection(cs))
{
SqlCommand cmd = new SqlCommand("spGetAddressByindex", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter()
{
ParameterName = "@term",
Value = term
});
con.Open();
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
listAddress.Add(rdr["Address"].ToString());
}
}
JavaScriptSerializer js = new JavaScriptSerializer();
context.Response.Write(js.Serialize(listAddress));
}
