想用Ajax想向Controller发送请求和接收返回的字符等等。Controller中要使用@ResponseBody注解。
<script type="text/javascript">
function loadXMLDoc()
{
if (window.XMLHttpRequest){
var request = new XMLHttpRequest();
var url = "http://localhost:8080/TestJson/ajaxController/testAjax?time=" + new Date();
//open中的第三个参数要用true,表示异步的
request.open("GET", url, true);
request.send();
request.onreadystatechange = function(){
if(request.readyState == 4 && request.status == 200){
document.getElementById("myDiv").innerHTML=request.responseText;
}
}
}else{
}
}
</script>
----
@RequestMapping(value="testAjax", method=RequestMethod.GET) public @ResponseBody String testAjax(@RequestParam(name="time") String time, ModelAndView modelAndView) throws InterruptedException { // Thread.sleep(8000); System.out.println("请求发送到服务器"); System.out.println(time); modelAndView.setViewName("testAsync"); String link = "<a href='http://www.baidu.com'>www.baidu.com</a>"; return link; }
