jquery:ajax 获取请求不起作用

我正在尝试使用 get 请求调用以下网址。

当我在浏览器中打开上述网址时，我收到以下响应。

[{"firstName":"Hari Krishna","id":1,"lastName":"Gurram","permAddrees":{"area":"Marthali","city":"Bangalore","country":"India","state":"Karnataka"},"tempAddrees":{"area":"Electronic City","city":"Bangalore","country":"India","state":"Karnataka"}},{"firstName":"PTR","id":2,"lastName":"PTR","permAddrees":{"area":"Bharath Nagar","city":"Hyderabad","country":"India","state":"Andhra Pradesh"},"tempAddrees":{"area":"BTM Layout","city":"Bangalore","country":"India","state":"Karnataka"}}]

以下是我的 jquery 片段。

<!DOCTYPE html>
<html>
    <head>
        <script src = "jquery-3.1.0.js"></script>
    </head>

    <body>  
        <h1>Click the below button to see the AJAX response</h1>
        <input type="submit" value="click here" id="button1" />

        <div id="placeHolder">

        </div>


        <script type="text/javascript">
            var jq = jQuery.noConflict();

            jq(document).ready(function(){
                jq("#button1").click(function(){
                    alert("Hello");
                    jq.get("http://localhost:8080/abc/employees", function(data, status){
                        alert(data + "" + status);
                        jq("#placeHolder").html(response);
                    });
                });
            });
        </script>
    </body>
</html>

当我单击按钮时，它显示第一个警报框“alert("Hello");”，但回调函数中的警报框未执行。任何人都可以帮我解决我的代码的问题吗？
