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 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;
