<script type="text/javascript">
var names = new Array();
$.ajax({
url : "Result",
type : 'POST',
data : {
"names" : JSON.stringify(names),//or names.join()
"globalClassId" : globalClassId
}});
</script>

If you are getting error 400 (Bad request) ????????????
如果您收到错误 400（错误请求）????????????
when you pass array data ({names:names} in your case ) to $.ajax() method then it append squre brackets [] after the paremeter name (means paremeter names will be names[] //not names)
当您将数组数据（在您的情况下为 {names:names} ）传递给 $.ajax() 方法时，它会在参数名称后附加方括号 []（意味着参数名称将是名称 [] //不是名称）
therefor you need some changes in your code
因此您需要对代码进行一些更改
@RequestMapping(value = "addResult", method = RequestMethod.POST)
public String addResult(ResultForm form,
BindingResult result, Model model,
@RequestParam("names[]") String[] names, //replace names with names[]
@RequestParam("globalClassId") String globalClassId)
throws Exception {
-------------
------------
return "";
}
or you can use
或者你可以使用
@RequestMapping(value = "addResult", method = RequestMethod.POST)
public String addResult(ResultForm form,
BindingResult result, Model model,
@RequestParam("globalClassId") String globalClassId)
throws Exception {
String[] names = request.getParameterValues("names[]");//getting names array here
-------------
------------
return "";
}
