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 class="lazy" data-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-class="lazy" data-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 >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 >= 10 ">
<div ng-show='catinfo.busy' align="center" ><!--<img class="lazy" data-src="{{basepath}}images/729.GIF" >-->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
$scope.catinfo = new catInfoService();
封装上拉加载CatInfoService.js
define(['jquery','app'], function ($,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;
}] );
});
效果
