ajax遍歷Map轉JSONArray

後臺：

/**
	 * 根據角色初始勾選菜單
	 * @param request
	 * @param response
	 */
	@RequestMapping("v_initMenu.aspx")
	public void initCheckedMenu(HttpServletRequest request , HttpServletResponse response){
		String jsonStr = "{\"result\":1}";
		String id=request.getParameter("roleId");
		List<TbAllianceRoleMenu> list = roleMenuService.findByRoleId(id);
		Map<String, String> map = new HashMap<String, String>();
		if(list != null){
			for (TbAllianceRoleMenu tbAllianceRoleMenu : list) {
				TbAllianceMenu menu = tbAllianceRoleMenu.getMenu();
				//String type = menu.getMenuType();
				//if(type != null && type.equals("btn")){
					map.put(menu.getId(), menu.getName());
				//}
			}
		}
		try {
			JSONArray json1 = JSONArray.fromObject(map);
			jsonStr = json1.toString();
			ResponseUtils.renderJson(response, jsonStr);
		} catch (Exception e) {
			log.error("initMenu", e);
            ResponseUtils.renderJson(response, jsonStr);
		}
	}

前臺：

		//初始勾選菜單
		var menuTreeObj = $.fn.zTree.getZTreeObj("businessTree");
		$.ajax({
