AngularJs分层结构小demo

后端mvc分层，前端也要分层才对嘛。分层的好处不言而喻。简直太清晰，容易维护。反正清爽的一逼。不信你看。

思路：分为controller层和service层。controller层再提取一个公共的层。比如放一些分页逻辑啦，格式化这类的方法。然后还有个module层。好的 齐活。

看代码：

base_pagination.js（这个是最大的module层，后面引入了个分页的module，分页必须得嘛）

var app=angular.module('pinyougou',['pagination']);

baseController.js （提取的公共controller层，分页，格式化转换，复选框方法，重新加载数据方法等等）

 //品牌控制层
app.controller('baseController' ,function($scope){    

    //重新加载列表 数据
    $scope.reloadList=function(){
        //切换页码
        $scope.search( $scope.paginationConf.currentPage, $scope.paginationConf.itemsPerPage);
    }

    //分页控件配置
    $scope.paginationConf = {
         currentPage: 1,
         totalItems: 10,
         itemsPerPage: 10,
         perPageOptions: [10, 20, 30, 40, 50],
         onChange: function(){
             $scope.reloadList();//重新加载
          }
    }; 

    $scope.selectIds=[];//选中的ID集合 

    //更新复选
    $scope.updateSelection = function($event, id) {
        if($event.target.checked){//如果是被选中,则增加到数组
            $scope.selectIds.push( id);
        }else{
            var idx = $scope.selectIds.indexOf(id);
            $scope.selectIds.splice(idx, 1);//删除
        }
    }

    $scope.jsonToString=function(jsonString,key){

        var json= JSON.parse(jsonString);
        var value="";

        for(var i=0;i<json.length;i++){
            if(i>0){
                value+=",";
            }
            value +=json[i][key];
        }

        return value;
    }

});    

brandController.js（那这里就是一些调用service的控制器了，没啥好说的）

 //控制层
app.controller('brandController' ,function($scope,$controller   ,brandService){    

    $controller('baseController',{$scope:$scope});//继承

    //读取列表数据绑定到表单中
    $scope.findAll=function(){
        brandService.findAll().success(
            function(response){
                $scope.list=response;
            }
        );
    }    

    //分页
    $scope.findPage=function(page,rows){
        brandService.findPage(page,rows).success(
            function(response){
                $scope.list=response.rows;
                $scope.paginationConf.totalItems=response.total;//更新总记录数
            }
        );
    }

    //查询实体
    $scope.findOne=function(id){
        brandService.findOne(id).success(
            function(response){
                $scope.entity= response;
            }
        );
    }

    //保存
    $scope.save=function(){
        var serviceObject;//服务层对象
        if($scope.entity.id!=null){//如果有ID
            serviceObject=brandService.update( $scope.entity ); //修改
        }else{
            serviceObject=brandService.add( $scope.entity  );//增加
        }
        serviceObject.success(
            function(response){
                if(response.success){
                    //重新查询
                    $scope.reloadList();//重新加载
                }else{
                    alert(response.message);
                }
            }
        );
    }

    //批量删除
    $scope.dele=function(){
        //获取选中的复选框
        brandService.dele( $scope.selectIds ).success(
            function(response){
                if(response.success){
                    $scope.reloadList();//刷新列表
                    $scope.selectIds=[];
                }
            }
        );
    }

    $scope.searchEntity={};//定义搜索对象 

    //搜索
    $scope.search=function(page,rows){
        brandService.search(page,rows,$scope.searchEntity).success(
            function(response){
                $scope.list=response.rows;
                $scope.paginationConf.totalItems=response.total;//更新总记录数
            }
        );
    }

});    

brandService.js

//服务层
app.service('brandService',function($http){

    //读取列表数据绑定到表单中
    this.findAll=function(){
        return $http.get('../brand/findAll.do');
    }
    //分页
    this.findPage=function(page,rows){
        return $http.get('../brand/findPage.do?page='+page+'&rows='+rows);
    }
    //查询实体
    this.findOne=function(id){
        return $http.get('../brand/findOne.do?id='+id);
    }
    //增加
    this.add=function(entity){
        return  $http.post('../brand/add.do',entity );
    }
    //修改
    this.update=function(entity){
        return  $http.post('../brand/update.do',entity );
    }
    //删除
    this.dele=function(ids){
        return $http.get('../brand/delete.do?ids='+ids);
    }
    //搜索
    this.search=function(page,rows,searchEntity){
        return $http.post('../brand/search.do?page='+page+"&size="+rows, searchEntity);
    }
    //下拉列表数据
    this.selectOptionList=function(){
        return $http.get('../brand/selectOptionList.do');
    }

});
