我正在练习 jquery ajax 调用。当我运行我的项目时会发生什么情况,它给出了 INTERNAL SERVER ERROR 500。这个错误是什么意思,我如何遇到这个错误?
我创建了一个示例项目,在其中添加了以下代码:
namespace sample
{
public partial class jqAjaxcall : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
GetDateTime();
}
[WebMethod]
private static string GetDateTime()
{
return DateTime.Now.ToString();
}
}
}
我的 aspx 代码文件:
<script type="text/javascript" src="Library/js/jquery-1.9.1-min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
// Add the page method call as an onclick handler for the div.
$("#Result").click(function () {
$.ajax({
type: "POST",
url: "jqAjaxcall.aspx/GetDateTime",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
// Replace the div's content with the page method's return.
$("#Result").text(msg.d);
}
});
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div id="Result">
Click here for the time.</div>
</form>
</body>
</html>
