否，您不需要重新加载页面，尤其是因为您使用的是异步请求(中的 A AJAX )添加到相同的网址.

No you don't need to reload the page, especially since you are utilizing an asynchronous request (the A in AJAX) to the same URL.

请参见此phpfiddle 演示您的示例(进行了一些修改).单击运行-F9 按钮，然后单击标有 Board 的按钮以运行JavaScript(带有AJAX请求).如果打开浏览器控制台，则应该在网络标签中看到请求.主要的应该是对 code_41096139.php 之类的页面的GET请求(数字可能会发生变化).然后，当发出AJAX请求时，应该对同一页面有一个POST请求.展开该请求，您应该会看到表单数据.

See this phpfiddle demonstrating your example (with a couple modifications). Click the Run - F9 button and then click the button labeled Board to run the JavaScript (with the AJAX request). If you open the browser console, you should see the requests in the Network tab. The main one should be a GET request to a page like code_41096139.php (the numbers will likely change). Then when the AJAX request is made, there should be a POST request to that same page. Expand that request and you should see the Form data.

除了添加按钮和单击处理程序外，所做的唯一修改是添加输出元素:

The only modifications made, besides adding the button and click handler, were to add the output element:

<div id="output"></div>

，然后在AJAX请求的成功回调中，将该元素的文本设置为响应(除了对console.log()的调用):

and then in the success callback of the AJAX request, set the text of that element to the response (in addition to the call to console.log()):

 success: function(response) {
      $('#output').text('response: '+response);
      console.log(response);
 }
