我做了一个struts应用程序。头版是具有表单和图像的jsp。如果您在字段中输入任何数据并单击图像，它将搜索该特定值的详细信息并将其打印在同一页面的 div 中。返回的数据是带有复选框和值的表格形式。这种表格格式位于另一个jsp页面中。我这样做是Ajax为了获取所有值并将其显示在同一页面上，因此我不需要一直刷新。

`document.getElementById("prtCnt").innerHTML=xmlhttp.responseText;`


where "prnCnt" is the Id of that div.

现在我想检查一些复选框并提交整个表单（表单上已经存在字段以及带有复选框的表值）。

我应该怎么做？

abc.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
   <%@taglib uri="/WEB-INF/struts-html" prefix="html"%>

    var value = document.getElementById("client").value;
    loadContent(value);

<html:form action="AjaxAction.do" >
    <html:text property="client"  value="ankit"  styleId="client" /> <img

</html>`

ajaxjs.js

var xmlhttp; function loadContent(value) { xmlhttp=GetXmlHttpObject(); if (xmlhttp==null) { alert ("Your browser does not support Ajax HTTP"); return; } url="AjaxAction.do?client="+value; xmlhttp.onreadystatechange=getOutput; xmlhttp.open("post",url,true); xmlhttp.send(null); } function getOutput() { if (xmlhttp.readyState==4) { alert(xmlhttp.responseText); document.getElementById("prtCnt").innerHTML=xmlhttp.responseText; } } function GetXmlHttpObject() { if (window.XMLHttpRequest) { return new XMLHttpRequest(); } if (window.ActiveXObject) { return new ActiveXObject("Microsoft.XMLHTTP"); } return null; }

tableshow.jsp

enter code here
