如何使用Ajax刷新表

I am working on a struts application and on a jsp page, there are two controls: 1. Dropdown 2. Table When first time page loads, Table is displayed on the page using "logic:iterate" tag from struts library. Now, I have a requirement that when user changes the dropdown value, corresponding table rows should be filtered based on the value. I am implementing this with the Ajax call to the server and I am getting the filtered results in the list. But I am not sure how I will refresh the table. Is there a way that through Ajax I can refresh the table so that logic:iterate will again be called? Otherwise, I have to display a new table with new set of results and somehow add a mechanism to hide the old logic:iterate table.

我正在开发一个struts应用程序，在jsp页面上，有两个控件：1。Dropdown 2. Table第一次加载页面时，使用struts库中的“logic：iterate”标签在页面上显示Table。现在，我要求当用户更改下拉列值时，应根据值过滤相应的表行。我正在通过对服务器的Ajax调用来实现这一点，并且我在列表中获得了过滤结果。但我不确定如何更新表格。有没有办法通过Ajax我可以刷新表，以便再次调用逻辑：iterate？否则，我必须显示一个包含新结果集的新表，并以某种方式添加一种机制来隐藏旧逻辑：iterate table。

Thanks for the help!

Support you got a table with id = "listTable" to refresh the table with ajax, do this

支持你有一个id =“listTable”的表来用ajax刷新表，执行此操作

document.getElementById("listTable").innerHTML=xmlHttp.responseText; 

where it will feed the return from the server into the table.

它将从服务器返回到表中。
