使用javascript调用网络服务 [英] Call Webservice using javascript
本文介绍了使用javascript调用网络服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我创建了一个Web服务，名称为" WebService ".
该Web服务具有一个称为" GetStudentdata "的网络方法.
这是网络方法代码:
I have created one webservice which name is " WebService ".
This webservice has one webmethod called "GetStudentdata".
here is the webmethod code:
[WebMethod]
public List<student> GetStudentdata()
{
student objstudent;
string str = ConfigurationManager.ConnectionStrings["connection_String"].ConnectionString;
SqlConnection conn = new SqlConnection(str);
SqlCommand cmd = new SqlCommand("sp_getStudentData", conn);
cmd.CommandType = CommandType.StoredProcedure;
///SqlDataAdapter to populate our DataSet
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = cmd;
///DataSet to hold the users information
DataTable dsInfo = new DataTable();
try
{
adapter.Fill(dsInfo);
//return the DataSet to the calling aspx page
List<student> drlist = new List<student>();
foreach (DataRow row in dsInfo.Rows)
{
objstudent = new student();
objstudent.rollnumber = Convert.ToInt32(row["Rollno"]);
objstudent.studentname = row["Studentname"].ToString();
objstudent.subject = row["Subject"].ToString();
drlist.Add(objstudent);
}
return drlist;
}
catch (Exception ex)
{
System.Web.HttpContext.Current.Response.Write(ex.Message);
return null;
}
finally
{
}
}
public class student
{
public int rollnumber;
public string studentname;
public string subject;
}
现在，我已将此Webservice调用到我的.aspx页面中
这是.aspx页面代码.
Now, I have called this webservice in to my .aspx page
here is the .aspx page code.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="jquery-1.7.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
function call() {
$.ajax({
type: "GET",
url: "http://localhost:2156/Websitetesting/WebService.asmx/GetStudentdata",
dataType: document.json,
error: function (xhr, ajaxOptions, thrownError) { alert('error:' + xhr.status); },
success: function (xmlDoc) {
var abc;
$(xmlDoc).find("ArrayOfStudent").each(function ()
{
$(this).find("student").each(function () {
abc.value = abc + $(this).find('rollnumber').text();
abc.value = abc + $(this).find('studentname').text();
abc.value = abc + $(this).find('subject').text();
alert(abc.value);
});
});
}
});
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="call();return false;" />
</form>
</body>
</html>
我的网络服务将这样的数据返回给我.
My webservice return me the data like this.
<arrayofstudent>
<student>
<rollnumber>1</rollnumber>
<studentname>ABC</studentname>
<subject>Maths</subject>
</student>
<student>
<rollnumber>2</rollnumber>
<studentname>Xyz</studentname>
<subject>Computer</subject>
</student>
<student>
<rollnumber>3</rollnumber>
<studentname>Pqr</studentname>
<subject>Science</subject>
</student>
</arrayofstudent>
我想使用javascript将这些数据显示到datagrid中，
但我做不到.
所以请任何人都可以帮助我.
在此先感谢.
