my table have a field Id which is identity, autoincrement and zerofill, starts with 000001. Thats ok, Im using ajax and c# web service, my query is this: 我的表有一个字段ID,即身份,autoincrement和zerofill,以000001开头。好吧,我使用ajax和c#web服务,我的查询是这样的:
sql = "Select Id FROM table WHERE (Owner ='" + us + "')";
This is my WebMethod 这是我的WebMethod
public string IdRegis(string us)
{
string resp = "";
DataTable dt = conn.ConsultTable("id", us);(This is query at top)
Opc2 op;
List<Opc2> lista = new List<Opc2>();
for (int i = 0; i < dt.Rows.Count; i++)
{
op = new Opc2((string)dt.Rows[i]["Id"].ToString());
lista.Add(op);
op = null;
}
JavaScriptSerializer js = new JavaScriptSerializer();
resp = js.Serialize(lista);
return resp;
}
And this is mi class 这是mi课程
public class Opc2
{
public Opc2() { }
public Opc2(string item)
{
Item = item;
}
public string Item { get; set; }
}
And ajax success function: 和ajax成功功能:
success: function (data) {
var options = '<option disabled="disabled" selected="selected">Select an option...</option>';
var datas = JSON.parse(data.d);
for (var i = 0; i < datas.length; i++) {
var id = ("00000" + (parseInt(datas[i].Id)));
var zerofillid = id.substring(id.length - 5);
options += '<option value ="' + zerofillid + '">';
options += zerofillid;
options += '</option>';
}
$('#id').html(options);
}
My select gets this values 00NaN. 我的选择获得此值00NaN。
Please change your javascript loop as given below. 请更改您的javascript循环,如下所示。
for (var i = 0; i < datas.length; i++)
{
// changed id to Item in this line
var id = ("00000" + (parseInt(datas[i].Item)));
var zerofillid = id.substring(id.length - 5);
optiones += '<option value ="' + zerofillid + '">';
options += zerofillid;
options += '</option>';
}
