使用JQuery进行Ajax调用
[英]Ajax calls using JQuery
问题描述
我是第一次使用jquery进行此ajax调用。 我试图绑定数据库中的值。 我有一个数据访问层，数据是从那里返回的。 我正在尝试将此数据集绑定到我的.aspx页中的gridview。 我已经在.aspx页面中编写了ajax jquery调用，但出现“未定义”错误。
请指导我哪里出了问题。
我的代码是
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="Scripts/jquery-2.1.4.js"></script>

<script>
$(function () {
$("#form1").validate({
rules: {
txtName: "required",
txtCity: "required",
ddlDepName: "required",
txtSalary: {
required: true,

},
},

txtName: "Please enter your Name",
txtCity: "Please enter your City",
ddlDepName: "Please select a department Name from the dropdown list",
txtSalary: {
required: "Please enter the Salary",

}
},
submitHandler: function (form) {
form.submit();
}
});
$('#btnInsertEmployee').click(function () {

}
});
});
$(function () {

确保您的服务器正在返回数据：您已使用
'POST'到'GET'数据...DataAccessLayer.cs/GetEmployees不是有效的网址。 要么调用网页（.aspx），要么调用Web方法，但是您没有从浏览器中调用DAL中的C＃文件（.cs）...
使用jquery双重调用ajax
