  • ionic 上拉加载更多&瀑布流加载&滚动到底部加载更多 主意事项

    首先下拉刷新的代码是这样的,标红的地方为关键代码

        <script src="http://www.runoob.com/static/ionic/js/ionic.bundle.min.js"></script>
        <script type="text/javascript">
         angular.module('starter', ['ionic'])
    
          .run(function($ionicPlatform) {
            $ionicPlatform.ready(function() {
              // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
              // for form inputs)
              if(window.cordova && window.cordova.plugins.Keyboard) {
                cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
              }
              if(window.StatusBar) {
                StatusBar.styleDefault();
              }
            });
          })
    
          .controller( 'actionsheetCtl',['$scope','$timeout' ,'$http',function($scope,$timeout,$http){
    
              $scope.items=[
                  {
                      "name":"HTML5"
                  },
                  {
                      "name":"JavaScript"
                  },
                  {
                      "name":"Css3"
                  }
              ];
    
              $scope.doRefresh = function() {
                  $http.get('http://www.runoob.com/try/demo_source/item.json')   //注意改为自己本站的地址,不然会有跨域问题
                      .success(function(newItems) {
                          $scope.items = newItems;
                      })
                      .finally(function() {
                          $scope.$broadcast('scroll.refreshComplete');
                      });
              };
          }])
        </script>
        </head>
        <body ng-app="starter" ng-controller="actionsheetCtl" >
    
            <ion-pane>
                <ion-content >
                    <ion-refresher pulling-text="下拉刷新" on-refresh="doRefresh()"></ion-refresher>
                    <ion-list>
                        <ion-item ng-repeat="item in items" ng-bind="item.name"></ion-item>
                    </ion-list>
                </ion-content>
            </ion-pane>
        </body>
    </html>

    默认打开页面是这样的

     /****************页面载入方法************************/
            $http.get(findUrl+'?class=goods&name='+name+'&page=1')   //注意改为自己本站的地址,不然会有跨域问题
                      .success(function(newItems) {
                          $scope.items = newItems.content;
                      })
                      .finally(function() {
                          $scope.$broadcast('scroll.refreshComplete');
                      });
    <ion-list>
        <div class="content   ionic-pseudo card" ng-repeat="item in items"  >

    上拉加载更多可以模仿下拉刷新写

    首先在</ion-list>下及</ion-content>上(不一定非得是</ion-list>,这里是放在列表最下方的意思)上放置代码

    。。。。。
    
                </ion-list>
                    <ion-infinite-scroll ng-if="!noMorePage" immediate-check="false" on-infinite="loadMore()" distance="1%" ></ion-infinite-scroll>       
            </ion-content>
        </body>
    </html>

    immediate-check="false"是实验了很多次后来加上的,具体见:http://feifei.im/archives/276

    然后是js代码部分

    $scope.currentPage=1;//定义下拉加载分页的初始值
    
    $scope.loadMore=function(){
        
        var start = $scope.start;
        var goods = $scope.goods;
        var now_city = $scope.now_city;
        $scope.currentPage += 1;//每当滚动到底部,页码累计加1
    
        $http.get(findUrl+'?class=goods&start='+start+'&goods='+goods+'&now_city='+now_city+'&page='+$scope.currentPage)   //注意改为自己本站的地址,不然会有跨域问题
            .success(function(newItems) {      
                for (var i=0;i<newItems.content.length;i++){//newItems.content.length,当前json的数量
                    $scope.items.push(newItems.content[i]);//一个一个取出来,推送到原来的items里
                }
                if (newItems.content.length < 10) {//当json的数量小于10(已经确定了一页为10条数据),说明页面到底了
                    $scope.noMorePage=true;//禁止滚动触发时间
                } 
                $scope.$broadcast('scroll.infiniteScrollComplete');        
            })
    };

    $scope.currentPage这个值会一直跑,一直累计加1,当你刷新页面后,这就会是个bug,所以,在下拉刷新代码里添加了

    $scope.currentPage=1;
    $scope.noMorePage=false;

    还原代码
