js ajax调用API问题

我想用AJAX调用一个接口地址，传回来的数据显示在页面上，但是一直报错，哪位可以帮忙看一下吗，多谢。
代码是要怎么写，谢谢
下面是页面代码<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm4.aspx.cs" Inherits="webtest.WebForm4" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">

    <title></title>
    <script src="./scripts/jquery.min.js"></script>
    <script type="text/javascript">
        function RequestBy(code) {
           
            //var url = 'http://q.stock.sohu.com/hisHq?code=cn_300450&start=20171120&end=20171131&stat=3&order=D&period=d&callback=?&rt=jsonp';

                type: "get",
                async: false,
                url: url,
                //  cache: false,
                dataType: "jsonp",
                 jsonp: "callback",
                jsonpCallback: "historySearchHandler",
                success: function (data) {
                    document.getElementById("data").innerHTML = data;
                    alert("success");
                },
                error: function (xhr, status, statusText) {
                    alert(xhr.status);
                    alert(statusText);
                    alert(xhr);
                    document.getElementById("data").innerHTML = statusText;
                }
            });
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">        <div>
            <input id="One" type="button" value="JsCallWebService" onclick="RequestBy()" />
