对于大多数web应用来说显示项目列表是一种很常见的任务。通常情况下，我们的数据会比较多，无法很好地显示在单个页面中。在这种情况下，我们需要把数据以页的方式来展示。
页面展示效果：
页面HTML代码：
<table class="table table-striped" style="margin: 0px;">
<thead>
<tr>
<td>选择</td>
<td>企业名称</td>
<td>企业地址</td>
<td>状态</td>
</tr>
</thead>
<tbody>
<tr ng-repeat="l in list">
<td><input type="radio" name="id" ng-click="select(l.id)" value="{{l.id}}" /></td>
<td>{{l.name}}</td>
<td>{{l.address}}</td>
<td>{{l.status_str}}</td>
</tr>
</tbody>
</table>
<!-- paging -->
<ul class="pagination" style="margin: 0px;" >
<li ng-class="{true:'disabled'}[p_current==1]"><a href="javascript:void(0);" ng-click="p_index()">首页</a></li>
<li ng-repeat="page in pages" ng-class="{true:'active'}[p_current==page]"><a href="javascript:void(0);" ng-click="load_page(page)">{{ page }}</a></li>
<li ng-class="{true:'disabled'}[p_current==p_all_page]"><a href="javascript:void(0);" ng-click="p_last()">尾页</a></li>
</ul>
<span style="vertical-align: 12px;"> 共：{{count}} 条</span>
</div>
Js代码：
var app = angular.module("myApp",[]);
app.controller("map_ctrl",function($scope,$http,$location){
//配置
$scope.count = 0;
$scope.p_pernum = 10;
//变量
$scope.p_current = 1;
$scope.p_all_page =0;
$scope.pages = [];
//初始化第一页
_get($scope.p_current,$scope.p_pernum,function(){
alert("我是第一次加载");
});
//获取数据
var _get = function(page,size,callback){
$http.get("xxx.html?status=0&page="+page+"&size="+size).success(function(res){
if(res&&res.status==1){
$scope.count=res.count;
$scope.list=res.list;
$scope.p_current = page;
$scope.p_all_page =Math.ceil($scope.count/$scope.p_pernum);
reloadPno();
callback();
}else{
alert("加载失败");
}
});
}
//单选按钮选中
$scope.select= function(id){
alert(id);
}
//首页
$scope.p_index = function(){
$scope.load_page(1);
}
//尾页
$scope.p_last = function(){
$scope.load_page($scope.p_all_page);
}
//加载某一页
$scope.load_page = function(page){
_get(page,$scope.p_pernum,function(){ });
};
//初始化页码
var reloadPno = function(){
$scope.pages=calculateIndexes($scope.p_current,$scope.p_all_page,8);
};
//分页算法
var calculateIndexes = function (current, length, displayLength) {
var indexes = [];
var start = Math.round(current - displayLength / 2);
var end = Math.round(current + displayLength / 2);
if (start <= 1) {
start = 1;
end = start + displayLength - 1;
if (end >= length - 1) {
end = length - 1;
}
}
if (end >= length - 1) {
end = length;
start = end - displayLength + 1;
if (start <= 1) {
start = 1;
}
}
for (var i = start; i <= end; i++) {
indexes.push(i);
}
return indexes;
};
});
</div>
分页算法：
current ：当前页码，length：总页码，displayLength：显示长度 @return array[1,2,3,4,5,6,7,8]
var calculateIndexes = function (current, length, displayLength) {
var indexes = [];
var start = Math.round(current - displayLength / 2);
var end = Math.round(current + displayLength / 2);
if (start <= 1) {
start = 1;
end = start + displayLength - 1;
if (end >= length - 1) {
end = length - 1;
}
}
if (end >= length - 1) {
end = length ;
start = end - displayLength + 1;
if (start <= 1) {
start = 1;
}
}
for (var i = start; i <= end; i++) {
indexes.push(i);
}
return indexes;
};
</div>
