Javascript 将参数从ajax函数传递到aspx.cs文件

我已经用HTML、JS和AJAX创建了一些代码，但它并没有按照我所希望的方式工作

<script type="text/javascript">
function DeleteSelectedRecord(id) {
            alert(id);
            $.ajax({
                type: "POST",
                url: "PrintTasks.aspx/DeleteRecord",
                data: '{"id":"' + id + '"}',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function () {
                    alert("Deleted!");
                },
                failure: function () {
                    alert("Failure!");
                }
            });

        }
    function CreateATableFromDataBase() {
        var deserializedData = '<%=serializedList %>';
            deserializedData = JSON.parse(deserializedData);
            for (var i = 0; i < deserializedData.length; i++) {
                document.write(
                    "<tr>" +
                    "<th scope=\"row\">" + i.toString() + "</th>" +
                    "<th>" + deserializedData[i]["Name"] + "</th>" +
                    "<th>" + deserializedData[i]["Where"] + "</th>" +
                    "<th>" + deserializedData[i]["Destination"] + "</th>" +
                    "<th><input type=\"button\" class=\"btn btn-primary\" onclick=\"DeleteSelectedRecord(" + deserializedData[i]["Id"] + ")\" value=\"Delete\"/></th>" +
                    "</tr>"
                );
            }
    }
</script>

里面有什么并不重要。最奇怪的是它没有读取我的参数

谢谢大家!

Try by changing your ajax code
            $.ajax({
                type: "POST",
                url: "PrintTasks.aspx/DeleteRecord",
                data: '{"id":"' + ParseInt(id) + '"}',//change your code here
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function () {
                    alert("Deleted!");
                },
                failure: function () {
                    alert("Failure!");
                }
            });

只需更改这行代码。它会起作用的

改为

第一个id是在.cs文件方法中设置的参数名称。。第二 一个是你要传递的价值

尝试如下所述：

$.ajax({
                type: "POST",
                url: "PrintTasks.aspx/DeleteRecord?id=" + id,
                success: function () {
                    alert("Deleted!");
                },
                failure: function () {
                    alert("Failure!");
                }
            });

使用$.param（）函数将数据发送到服务器。 代码如下：

       $.ajax({
           type: "POST",
            url: "PrintTasks.aspx/DeleteRecord",
            data: $.param({"id": id}),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function () {
                alert("Deleted!");
            },
            failure: function () {
                alert("Failure!");
            }
        });

            failure: function () {

            }
        });

这一个仍然在创建一个匿名对象作为字符串！这一个仍然在创建一个匿名对象作为字符串！
