我正在尝试从 jquery 获取 wcf 服务。我写了下面的代码，但出现错误。

jQuery代码：

function LoadAutoComplete(method, param) {

    firstIncrement = pageSize + 1;
    $.ajax({
        type: "POST",
        url: "Services/Popup.svc/" + method,
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        data: params,
        processdata: true,
        success: function (data) {

            if (data.PopupData != null) {
                alert(data);
            }
            else {
                //response = null;
                //return response;
            }
        },
        error: function (result) { alert("Error"); }
    });
}

function LoadTest(id) {
    var prm = "<%= this.Sequence %>";
    var params = '"sequence":' + prm;
    method = "GetNotes";

    LoadAutoComplete(method,params);
}

  <title></title>

<body>
  <form id="form1" runat="server">

  </form>

GetNotes 是我用业务逻辑编写的方法名称。

错误：Microsoft JScript 运行时错误：“$”未定义

您需要包含 jQuery，在其他标签上方添加以下脚本标签：

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
