如何从asp.cs方法获取javascript中的数据

Question

我有以下代码如何使用Java脚本绑定网格我想调用aspx.cs代码并检索数据并使用网格绑定而无需回发请帮助我。我是新的asp.net请帮帮我。我打电话给这个方法但没有成功

       <script type='text/javascript'>


                          $(document).ready(function () {

                              bindjs();

                          })

                          function bindjs() {

                              PageMethods.BindGrid(Success, Failure);
                          }
                          function Success(result) {
                              alert(result);
                          }
                          function Failure(error) {
                              alert(error);
                          }
</script>

和我的Asp.cs方法是

    [WebMethod]
    public static  DataTable BindGrid()
    {

        con = new SqlConnection(constr);
        da = new SqlDataAdapter("select tblStudent.student_id,tblStudent.student_name,tblStudent.father_name," +
            "tblStudent.Cell,tblStudent.parents_cell,tblStudent.admission_date,tblclassinfo.class_name,address_student" +
            " from tblStudent  inner join tblclassinfo on tblStudent.class_id =  tblclassinfo.class_id", con);



        DataTable dt = new DataTable();
        da.Fill(dt);
        return dt;

    }

Answer 1

您必须更改要从

继承的cs类

public class Service1 : System.Web.Services.WebService

然后你的方法如下

<WebMethod()> _
void BindGrid(string bookingInformation) {

    //your code here

}
