angular.js前端分层开发（页面和js代码分离，并将js代码分层）

Posted 2021-01-30 FLGB

一、

抽取模块成base.js文件
// 定义模块:
var app = angular.module("eshop",[‘pagination‘]);

二、

抽取服务成brandService.js文件

/ 定义服务层:
app.service("brandService",function($http){
    this.findAll = function(){
        return $http.get("../brand/findAll.do");
    }
    
    this.findByPage = function(page,rows){
        return $http.get("../brand/findByPage.do?page="+page+"&rows="+rows);
    }
    
    this.save = function(entity){
        return $http.post("../brand/save.do",entity);
    }
    
    this.update=function(entity){
        return $http.post("../brand/update.do",entity);
    }
    
    this.findById=function(id){
        return $http.get("../brand/findById.do?id="+id);
    }
    
    this.dele = function(ids){
        return $http.get("../brand/delete.do?ids="+ids);
    }
    
    this.search = function(page,rows,searchEntity){
        return $http.post("../brand/search.do?page="+page+"&rows="+rows,searchEntity);
    }
    
    this.selectOptionList = function(){
        return $http.get("../brand/selectOptionList.do");
    }
});

三、

抽取baseController，公共js文件
app.controller("baseController",function($scope){
    // 分页的配置的信息
    $scope.paginationConf = {
         currentPage: 1, // 当前页数
         totalItems: 10, // 总记录数
         itemsPerPage: 10, // 每页显示多少条记录
         perPageOptions: [10, 20, 30, 40, 50],// 显示多少条下拉列表
         onChange: function(){ // 当页码、每页显示多少条下拉列表发生变化的时候，自动触发了
            $scope.reloadList();// 重新加载列表
         }
    }; 
    
    $scope.reloadList = function(){
        // $scope.findByPage($scope.paginationConf.currentPage,$scope.paginationConf.itemsPerPage);
        $scope.search($scope.paginationConf.currentPage,$scope.paginationConf.itemsPerPage);
    }
    
    // 定义一个数组:
    $scope.selectIds = [];
    // 更新复选框：
    $scope.updateSelection = function($event,id){
        // 复选框选中
        if($event.target.checked){
            // 向数组中添加元素
            $scope.selectIds.push(id);
        }else{
            // 从数组中移除
            var idx = $scope.selectIds.indexOf(id);
            $scope.selectIds.splice(idx,1);
        }
        
    }
    
    // 定义方法：获取JSON字符串中的某个key对应值的集合
    $scope.jsonToString = function(jsonStr,key){
        // 将字符串转成JSOn:
        var jsonObj = JSON.parse(jsonStr);
        
        var value = "";
        for(var i=0;i<jsonObj.length;i++){
            
            if(i>0){
                value += ",";
            }
            
            value += jsonObj[i][key];
        }
        return value;
    }
    
});

四、

抽取业务controller成业务js文件
// 定义控制器:
app.controller("brandController",function($scope,$controller,$http,brandService){
    // AngularJS中的继承:伪继承
    $controller(‘baseController‘,{$scope:$scope});
    
    // 查询所有的品牌列表的方法:
    $scope.findAll = function(){
        // 向后台发送请求:
        brandService.findAll().success(function(response){
            $scope.list = response;
        });
    }

    // 分页查询
    $scope.findByPage = function(page,rows){
        // 向后台发送请求获取数据:
        brandService.findByPage(page,rows).success(function(response){
            $scope.paginationConf.totalItems = response.total;
            $scope.list = response.rows;
        });
    }
    
    // 保存品牌的方法:
    $scope.save = function(){
        // 区分是保存还是修改
        var object;
        if($scope.entity.id != null){
            // 更新
            object = brandService.update($scope.entity);
        }else{
            // 保存
            object = brandService.save($scope.entity);
        }
        object.success(function(response){
            // {flag:true,message:xxx}
            // 判断保存是否成功:
            if(response.flag==true){
                // 保存成功
                alert(response.message);
                $scope.reloadList();
            }else{
                // 保存失败
                alert(response.message);
            }
        });
    }
    
    // 查询一个:
    $scope.findById = function(id){
        brandService.findById(id).success(function(response){
            // {id:xx,name:yy,firstChar:zz}
            $scope.entity = response;
        });
    }
    
    // 删除品牌:
    $scope.dele = function(){
        brandService.dele($scope.selectIds).success(function(response){
            // 判断保存是否成功:
            if(response.flag==true){
                // 保存成功
                // alert(response.message);
                $scope.reloadList();
                $scope.selectIds = [];
            }else{
                // 保存失败
                alert(response.message);
            }
        });
    }
    
    $scope.searchEntity={};
    
    // 假设定义一个查询的实体：searchEntity
    $scope.search = function(page,rows){
        // 向后台发送请求获取数据:
        brandService.search(page,rows,$scope.searchEntity).success(function(response){
            $scope.paginationConf.totalItems = response.total;
            $scope.list = response.rows;
        });
    }
    
});

五、在页面引入js文件使用即可

    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
