实现

页面

 <div class="search-box">
 <b class="dw" ></b>
  <input type="search" class="search-input" placeholder="请输入搜索关键词" ng-model="catparm">
  <b class="dw" ng-click="serchcat()"><img src="{{basepath}}images/cg-app-search.png"></b>
 </div>
 <div class="list-box" >
  <div infinite-scroll='catinfo.nextPage()' infinite-scroll-disabled='catinfo.busy' infinite-scroll-distance='' id="catinfolist">
  <ul>
   <li ng-repeat='branch in catinfo.items'>
  <!-- <li ng-repeat="branch in branchs">-->
   <a ng-click="showqr(branch.qr)">
   <dl>
   <dt class="search-key-img">
    <img ng-src="{{branch.catimg}}">
   </dt> 
   <dd class="search-key-title">
    <p>{{branch.title}}</p>
    </dd>
    <dd class="search-key-info">
    <span>联系人:{{branch.linkman}} </span><span>品种:{{branch.varieties}} </span> <span style="color: red;">价格:{{branch.price}} </span>
    </dd>
    <dd class="search-key-tag">
    <span>地址:{{branch.region}}</span><span ng-if="branch.wechatno !=''">微信号:{{branch.wechatno}}</span>
    </dd>
    <dd class="search-key-tag">
     <p> 发布时间:{{branch.releasetime}}</p>
    </dd>
   </dl>
   </a>
  </li>
  </ul>
   <div ng-if="catinfo.items.length &gt;= 10 ">
    <div ng-show='catinfo.busy' align="center" style="margin-top:5px; "><!--<img src="{{basepath}}images/729.GIF" style="width:50px;height:50px;">-->loading......</div>
   </div>
   <div ng-if="catinfo.items.length % 10 !=0 ">
    <p class="get-more">我也是有底线的</p>
   </div>
  </div>
  <dialog load-data="data"></dialog>
 </div>

controller中上拉加载功能使用

app.controller('wdListCtrl', ['$scope','catInfoService', function ($scope,catInfoService) {
//下拉加载service
 $scope.catinfo = new catInfoService();

封装上拉加载CatInfoService.js

/** 2017-10-26

 */
define(['jquery','app'], function ($,app) {
 app.service('catInfoService', ['$location','$http', function($location,$http) {
  var CatInfo = function () {
   this.items =null;
   this.busy = false;
   this.after = '';
   this.page = 1;
   this.pagenum =10;
   this.title = '';
   this.varieties ='';
  };
  CatInfo.prototype.nextPage = function () {
   if (this.busy) return;
   this.busy = true;
   var url = baseurl+"接口地址?page=" + this.page + "&pagenum="+ this.pagenum + "&title="+this.title+ "&varieties="+this.varieties+"&callback=JSON_CALLBACK";
   $http.jsonp(url).success(function(data) {
    var items =data.data;
    console.log(items);
    if( this.items == null){
     this.items=items;
    }else{
     for (var i =0;i < items.length; i++) {
      this.items.push(items[i]);
     }
    }
    this.after = "t_" + this.items[this.items.length -1 ].id;
    if(items != null){
     if(items.length< 10){
      this.busy = true;
     }else{
      this.busy = false;
     }
    }
    this.page +=1;
   }.bind(this));
  };
  return CatInfo;
 }] );
});
