JSONP簡單實踐

<script>
    function handleResponse(response){
        console.log(response);
    }
    var script = document.createElement("script");
    script.src = "http://localhost:8088/C1-Planning/formDefinitionAction!loadFormTree.action?callback=handleResponse";
    document.body.appendChild
 
(script);
</script>

後端返回 handleResponse(…) 字串，前端就會呼叫了。

 response.getWriter().print("handleResponse("+JSONUtil.toJson(results)+")");
