這篇文章是講解 Ioinc中怎麼實現 下拉刷新和上拉加載的。也是我們日常做項目是必不可少的功能。有興趣的小夥伴可以來學習一下。
HTML部分
<ion-view view-title="消息通知">
<ion-content class="padding">
<!-- <ion-refresher> 下拉刷新指令 -->
<ion-refresher pulling-text="Pull to refresh" on-refresh="vm.doRefresh()"></ion-refresher>
<div class="list card" ng-repeat="message in vm.messages" >
<div class="item item-divider item-icon-right">`message`.`title`
<i class="icon" ng-click="vm.show(message)" ng-class="message.static?‘ion-arrow-down-b‘:‘ion-arrow-right-b‘"></i></div>
<div class="item item-body">
<div>
{{message.static?message.content:message.content.substr(0, 40)}}
</div>
</div>
</div>
<!-- ion-infinite-scroll 上拉加載數據指令 distance默認1% nf-if的值爲false時，就禁止執行on-infinite -->
<ion-infinite-scroll ng-if="!vm.moredata" on-infinite="vm.loadMore()" distance="1%" ></ion-infinite-scroll>
</ion-content>
</ion-view>JS部分
on-refresh 下拉觸發的函數 函數執行結束之前必須廣播下該事件結束 $scope.$broadcast(‘scroll.refreshComplete‘);
on-infinite 上拉觸發的函數 同樣需要廣播事件結束 $scope.$broadcast(‘scroll.infiniteScrollComplete‘);
angular.module(‘starter.controllers‘, [])
.controller(‘InfoCtrl‘, function($rootScope, $timeout, $interval, $scope, $http, services) {
var vm = $scope.vm = {
moredata: false,
messages: [],
pagination: {
perPage: 5,
currentPage: 1
},
init: function () {
services.getMessages({perPage: vm.pagination.perPage, page: vm.pagination.currentPage}, function (data) {
vm.messages = data;
})
},
show: function (message) {
if (message.static) {
message.static = false;
} else {
message.static = true;
}
},
doRefresh: function () {
$timeout(function () {
$scope.$broadcast(‘scroll.refreshComplete‘);
}, 1000);
},
loadMore: function () {
vm.pagination.currentPage += 1;
services.getMessages({perPage: vm.pagination.perPage, page: vm.pagination.currentPage}, function (data) {
vm.messages = vm.messages.concat(data);
if (data.length == 0) {
vm.moredata = true;
};
$scope.$broadcast(‘scroll.infiniteScrollComplete‘);
})
}
}
vm.init();
})此處的messages 是view顯示的數據，pagination是做分頁加載顯示的參數，service是我封裝的$http服務，show方法是view信息顯示的開關（這些都可以不用注意）！
