js传递参数问题----控制层方法中传值

1.方法括号不传值

{ window.location.href = "ghJfGameInfo.do?method=delMiGameBelong&rowId="+rowId;

public String delMiGameBelong(HttpServletRequest request)

Long rowId = this.getLongValue(request, "rowId");

2.关于返回值定义int 类型或String类型问题

public String deleteNotice (String id) {
String errCode = "&errCode=3";
try {
boolean result = noticeService.deleteNotice(id);
if (result) {
errCode = "&errCode=3";
} else {
errCode = "&errCode=-3";
}
} catch (Exception e) {
log.error("删除公告出错！", e);
}
return "redirect:notice.do?method=noticeList" + errCode;
} 前台 errCode = "?errCode=-15"; return backUrl + errCode;

String errCode = "&errCode=5";
