ie10停jquery ajax data参数在服务器端无法获取参数值跪求帮助

ie10下jquery ajax data参数在服务器端无法获取参数值跪求帮助
js代码
function addRole()
        {
        var roleName='哈哈哈';
        var roleDescr='哈哈哈';
        var msg="";
        if(null==roleName || ""==roleName){
        msg+="角色名称不能为空<br>";
        }
        if(null==roleDescr || ""==roleDescr){
        msg+="角色描述不能为空<br>";
        }
        if(null!=msg && ""!=msg){
        $.ligerDialog.alert(msg, '提示', 'warn');
        return false;
        }
        $.ajax({
              type:"POST",
              url:"<%=basePath%>company/saveRoleInfo.do?roleName="+encodeURI(encodeURI(roleName))+"&roleDescr="+roleDescr,
              data:{name:1},
              dataType:'text',
              contentType:"application/x-www-form-urlencoded:charset=UTF-8",
              success:function(data){
              if("true"==data){
              parent.f_closeTab('company_role_add');
              }else{
              $.ligerDialog.alert("角色添加失败,请稍后再试!", '提示', 'error');
              }
              }
           });
        }
后台代码：
@RequestMapping("company/saveRoleInfo.do")
public String saveRoleInfo(String roleName,String roleDescr,HttpServletRequest request,HttpServletResponse response){
try {
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
System.out.println( URLDecoder.decode(roleName,"UTF-8")+"\n"+roleDescr+"\n"+request.getParameter("name"));
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
//boolean flag=this.companyRoleService.saveRoleInfo(roleName, roleDescr);
try {
response.getWriter().write(Boolean.toString(true));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
输出结果中name总是null
js中的data:{name:1}以及data:"name="+1这两种方式都试过，均为null 求帮助
[解决办法]
试试  $.get("http://www.baoidu.com?a="，function(data){});这个能获取吗？我一直用这个的  都没问题
[解决办法]
contentType 貌似java用不上，可去掉

data:{'name':1}     //变量名用引号括起来
