jquery ajax调用

 最简单的jquery ajax在sturts中的应用

 

action:

public ActionForward ajaxTest() throws Exception {
	try {
		String val = getRequest().getParameter("val");
		val = "回应:" + val;
		getResponse().getOutputStream().print(val); // 放入response
	} catch (Exception e) {
		throw e;
	}
	return null; // 这里返回null
}

 jsp:

<%@ page language="java" contentType="text/html; charset=gbk" pageEncoding="gbk"%>
<html>
	<head>
		<title>ajax测试</title>
		<meta http-equiv="Content-Type" content="text/html; charset=gbk">
		<link href="<%=request.getContextPath()%>/css/style.css" rel="stylesheet" type="text/css">
		<script src="<%=request.getContextPath()%>/js/jquery-1.3.2.js" type="text/javascript"></script>
		<script src="<%=request.getContextPath()%>/js/ajaxTest.js" type="text/javascript"></script>
		<script type="text/javascript">
		</script>
	</head>
	<body>
		<form action="demo.do" method="post" id="demoForm">
			ajax测试
			<input type="text" id="val"/>
			<input type="text" id="result"/>
			<input type="button" id="btn" value="ajax"/>
		</form>
	</body>
</html>

 

 js:

$(document).ready(function() {
	$('#btn').bind('click', function() {
		$.ajax({
			url: 'demo.do?nextStep=ajaxTest',
			data: {'val': $('#val').val()},
			success : function(result) {
				$('#result').val(result);
			}
		});
	});
});
