如何发送 JSP 作为对 AJAX 调用的响应

Question

我想发送一个 JSP 页面，它由一些 div 和 table 组成，作为 Spring 框架的 AJAX 响应的一部分，有什么方法可以发送 JSP 作为 AJAX 调用的响应

Answer 1

Sending JSP by AJAX makes no sense, it is basically the HTML generated by a JSP that is sent over to the browser through AJAX, as rightly pointed out by the lost.

You do not need any server-side coding for this. All you need is to write some JavaScript on client-side to receive your HTML asynchronously. For this, I would recommend using some JavaScript framework like jQuery, otherwise, it would make your life hell.

Assuming that the page you want to access by AJAX has the link http://domain:port/mypage.htm . First you need to include jQuery in your base JSP (JSP in which former page has to load by AJAX):

<script type="text/javascript" src="${pageContext.request.contextPath}/js/jquery.js"></script>

Then you need to call jQuery's AJAX function:

$(document).ready(function(){
    $.ajax({
        type:"GET",
        url: "http://domain:port/mypage.htm",
        success: function(data) {
            // Now you have your HTML in "data", do whatever you want with it here in this function         
            alert(data);
        }
    });
});

Hope it helps!

Yes, there's no magic to this though. In your Java AJAX handler just return a forward or redirect to the JSP page you want. The response will then be available as the responseText in your AJAX callback.

You can use JSP to generate just the elements you need as a sort of incomplete HTML fragment then returns this from your server-side handler. Then in your JavaScript callback you can insert the fragment into your existing HTML like this

element.innerHTML = resp.responseText 
//element is the parent you want to insert to 
//resp is the parameter supplied to your callback
