前台没有显示 店铺分类和所属区域

这个是浏览器的报错信息，弄了很久还是这样，哪错了？

不建议同学注释，而是要去看看问题可能出在哪，只要调试一下，就会发现data.areaList是undefined的，导致再调用方法会报空指针异常，这个时候就需要看看后端是否真的返回了areaList以及前端是否接收到并展示，一步步排查，逐渐锻炼起独立解决问题的能力

• 提问者 qq_独闭关中_0 #1

  我以为那个方法是要注释了的

• 提问者 qq_独闭关中_0 #2

  private Map<String, Object> getShopInitInfo() {
  		Map<String, Object> modelMap = new HashMap<String, Object>();
  		List<ShopCategory> shopCategoryList = new ArrayList<ShopCategory>();
  		List<Area> areaList = new ArrayList<Area>();
  		try {
  			shopCategoryList = shopCategoryService.getShopCategoryList(new ShopCategory());
  			areaList = areaService.getAreaList();
  			modelMap.put("shopCategoryList", shopCategoryList);
  			modelMap.put("arealList", areaList);
  			modelMap.put("success", true);
  		} catch (Exception e) {
  			// TODO: handle exception
  			modelMap.put("success", false);
  			modelMap.put("errMsg", e.getMessage());
  		}
  
  		return modelMap;
  
  	}
  老师能帮我看看到底是哪里错了嘛？代码和你写的源码以一比对都没错啊，但是换成你的源码就可以了

  还是建议同学调试一下，看看areaList为什么为空，我直接看源码也看不出来，而且咱们实际工作中，也没有源码可以对比。如果再不济，建议你用beyondcompare等工具对比下代码，但是完全不建议那样做

注释了getShopInitInfo();就不报错了，但是还是没有显示出来，上面是运行后的信息

• 轩7628043 #1

  同學怎鹽解決的呀

• 提问者 qq_独闭关中_0 回复 轩7628043 #2

  后端没有传值过来

• 轩7628043 回复 提问者 qq_独闭关中_0 #3

  我這data裏面是有areaList，并且data.shopCategoryList.map(function(item,index)這個運行是沒問題的
