我无法将逗号分隔的字符串拆分为数组。在我的ashx处理程序页面中，我的字符串如下所示：
context.Response.Write(string.Format("{0},{1},{2},{3},{4},{5},{6},{7},{8},{9} ", BusProfileID, BusinessName, BusinessPhone, BusinessEmail, BusinessAddress, BusinessCity, BusinessState, BusinessZip, BusinessWebsite, BusinessCategory));
当我尝试做一个数组时，结果不显示。
<script>
$(document).ready(function () {
$('#ContentPlaceHolder1_businessSelect').change(function () {
$.ajax({
contentType: "text/html; charset=utf-8",
data: "ID=" + $('#ContentPlaceHolder1_businessSelect').val(),
url: "getBusValue.ashx",
dataType: "text",
success: function (data) {
var vardata = JSON.stringify(data)
var arr = vardata.split(',')
$("#ContentPlaceHolder1_BusProfileID").val(arr[0]);
$("#ContentPlaceHolder1_BusinessName").val(arr[1];
$("#ContentPlaceHolder1_BusinessPhone").val(arr[2]);
$("#ContentPlaceHolder1_BusinessEmail").val(arr[3]);
$("#ContentPlaceHolder1_BusinessAddress").val(arr[4]);
$("#ContentPlaceHolder1_BusinessCity").val(arr[5]);
$("#ContentPlaceHolder1_BusinessState").val(arr[6]).prop('selected',true);
$("#ContentPlaceHolder1_BusinessZip").val(arr[7]);
$("#ContentPlaceHolder1_BusinessWebsite").val(arr[8]);
$("#ContentPlaceHolder1_BusinessCategory").val(arr[9]).prop('selected', true);
}
});
});
});
</script>
这是我的ashx页面：
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/html";
string ID = context.Request.QueryString["ID"];
SqlConnection conn;
SqlCommand comm;
SqlDataReader reader;
string connectionString = ConfigurationManager.ConnectionStrings["Conn"].ConnectionString;
conn = new SqlConnection(connectionString);
comm = new SqlCommand("SELECT BusProfileID, BusinessName, BusinessPhone, BusinessEmail, BusinessAddress, BusinessCity, BusinessState, BusinessZip, BusinessWebsite, BusinessCategory FROM [BusProfile] WHERE BusinessName = @BusinessName", conn);
comm.Parameters.Add("@BusinessName", System.Data.SqlDbType.VarChar);
comm.Parameters["@BusinessName"].Value = ID;
try
{
conn.Open();
reader = comm.ExecuteReader();
if (reader.Read())
{
string BusProfileID = reader["BusProfileID"].ToString();
string BusinessName = reader["BusinessName"].ToString();
string BusinessPhone = reader["BusinessPhone"].ToString();
string BusinessEmail = reader["BusinessEmail"].ToString();
string BusinessAddress = reader["BusinessAddress"].ToString();
string BusinessCity = reader["BusinessCity"].ToString();
string BusinessState = reader["BusinessState"].ToString();
string BusinessZip = reader["BusinessZip"].ToString();
string BusinessWebsite = reader["BusinessWebsite"].ToString();
string BusinessCategory = reader["BusinessCategory"].ToString();
context.Response.Write(string.Format("{0},{1},{2},{3},{4},{5},{6},{7},{8},{9} ", BusProfileID, BusinessName, BusinessPhone, BusinessEmail, BusinessAddress, BusinessCity, BusinessState, BusinessZip, BusinessWebsite, BusinessCategory));
}
reader.Close();
}
finally
{
conn.Close();
}
}
这是成功后文本框中数据的样子：
8,My Business Inc,(702) 555-1212,123@aol.com,555 anywhere street,Los Angeles,California,44502,google.com,Hotel & Travel

以下是代码的演示。
var string = "8,my business inc,(702) 555-1212,123@aol.com,555 anywhere street,Los Angeles,california,44502,google.com,hotel and ttravel";
var stringArray = string.split(',');
console.log(stringArray);
结果如下：
[＆＃34; 8＆＃34;，＆＃34; my business inc＆＃34;，＆＃34;（702）555-1212＆＃34;，＆＃34; 123@aol.com& ＃34;，＆＃34; 555任何街道＆＃34;，＆＃34;洛杉矶＆＃34;，＆＃34;加利福尼亚＆＃34;，＆＃34; 44502＆＃34;，＆＃34; google.com＆ ＃34;，＆＃34;酒店和ttravel＆＃34;]
console.log(xm[5]);
输出： 洛杉矶
如果成功获得的数据是一个字符串，那么可能就是流程如何......
我认为您编写的代码中没有任何错误。
如果数据不是字符串，那么
执行var string = "" + data;将其转换为字符串。

这是一个lenthy帖子，但我希望它可以帮助你。
第一部分是使用两种不同方式的Web服务，一种是作为Web服务，另一种是作为列表并将其序列化的常规类。
webservice1.asmx：
namespace WebApplication1
{ // a class in context with how the data are is being used
[Serializable]
public class select2
{
public String id { get; set; }
public String text { get; set; }
public select2(String code, String name)
{
this.id = code;
this.text = name;
}
}
// input parms not used but to show concept
public struct parameters
{
string parm1;
string parm2;
}
/// <summary>
/// Summary description for WebService1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
[System.Web.Script.Services.ScriptService]
public class WebService1 : System.Web.Services.WebService
{
[WebMethod]
public string GetAList(String s)
{
System.Web.Script.Serialization.JavaScriptSerializer ser = new System.Web.Script.Serialization.JavaScriptSerializer();
parameters parms = ser.Deserialize<parameters>(s);
return makelist();
}
// return a list of serialized codes and countries
public String makelist()
{
List<select2> list = new List<select2>();
list.Add(new select2("AI", "Anguilla"));
list.Add(new select2("AQ", "Antarctica"));
list.Add(new select2("AG", "Antigua and Barbuda"));
list.Add(new select2("AR", "Argentina"));
list.Add(new select2("AM", "Armenia"));
list.Add(new select2("AW", "Aruba"));
list.Add(new select2("AU", "Australia"));
list.Add(new select2("AT", "Austria"));
list.Add(new select2("AZ", "Azerbaijan"));
list.Add(new select2("BS", "Bahamas"));
list.Add(new select2("BH", "Bahrain"));
list.Add(new select2("BD", "Bangladesh"));
list.Add(new select2("BB", "Barbados"));
list.Add(new select2("BY", "Belarus"));
list.Add(new select2("BE", "Belgium"));
list.Add(new select2("BZ", "Belize"));
// did it this way to show you which to use
System.Web.Script.Serialization.JavaScriptSerializer ser = new System.Web.Script.Serialization.JavaScriptSerializer();
String jsonList = ser.Serialize(list);
return jsonList;
}
}
}
下一节是后面的代码部分：
namespace WebApplication1
{
public partial class select2 : System.Web.UI.Page
{
public String JsonCountries { get
{
// use the web service as a regular class to return the serialized list
return (new WebService1()).makelist();
} }
protected void Page_Load(object sender, EventArgs e)
{
}
}
}
最后是一个aspx页面，它将一个select2框从ajax调用填充到web方法，而第二个select 2则是由后面的代码放入的数据填充的。它与你正在做的有点不同，但概念证明已经到位，应该给你足够的信息。
$(document).ready(
function () {
// property on code behnd
var cblist = <%=JsonCountries%>;
$("#sel3").select2({ data:cblist });
parms = JSON.stringify({ parm1: "one", parm2: "two" });
$.ajax({
url: "WebService1.asmx/GetAList",
data: JSON.stringify( {s:parms}),
type: 'post',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data, status) {
var contries = JSON.parse(data.d);
$("#sel2").select2({ data: contries });
},
error: function (one, two) {
debugger;
}
});
}
);
</script>
</head>
<body>
<div>
<p>populated from ajax</p>
<select id="sel2"></select>
</div>
<div>
<p>populated from code behind</p>
<select id="sel3"></select>
</div>
</body>
</html>
