AngularJs分页插件使用详解

angularUI bootstrap提供的分页插件满足了大部分应用的需求，具体内容如下

在项目需求中，新增了两个需求：

1.自由设定每页显示的条目；

2.可以手动输入页面，跳转到指定的页数。

html代码

<div class="pagination-define p20 mt20" ng-hide="totalItems==0">
 <select ng-model="perPageSize" ng-change="pageChanged({currentPage:currentPage,perPageSize:perPageSize})" >
  <option value=10 ng-selected="perPageSize==10">10</option>
  <option value=20>20</option>
  <option value=30>30</option>
  <option value=50>50</option>
  <option value=100>100</option>
 </select>
 <uib-pagination items-per-page="numPerPage" total-items="totalItems" ng-model="currentPage" ng-change="pageChanged({currentPage:currentPage,perPageSize:perPageSize})" max-size="5" class="pagination-sm" boundary-link-numbers="true" boundary-links="true" rotate="false" previous-text="‹" next-text="›" first-text="«" last-text="»"></uib-pagination>
 <input type="text" ng-model="inputCurPage" min=1 cus-max-number ="{{maxPages}}" current-page="{{currentPage}}">
 <button class="btn btn-info btn-30h" ng-click="pageChanged({currentPage:inputCurPage,perPageSize:perPageSize})" ng-disabled="inputCurPage==''||submitting">Go</button>
</div>

css代码

.pagination-define{
 text-align: center
}
.pagination-define input, .pagination-define select {
 padding-left: 3px;
 height: 30px;
 vertical-align: top;
 border: 1px solid #ccc;
 border-radius: 4px;
 width: 50px;
}
.pagination {
 margin: 0;
}
.pagination-define .btn-30h {
 vertical-align: top;
}
.btn-30h {
 padding-top: 4px;
 padding-bottom: 4px;
}

Javascript代码

app.directive('cusMaxNumber', ['$timeout', function ($timeout) {
  return {
   restrict: 'EA',
   require: 'ngModel',
   scope: {
    maxNumber: '@cusMaxNumber',
    currentPage: '@currentPage'
   },
   link: function (scope, element, attr, ctrl) {
    ctrl.$parsers.push(function (viewValue) {
     var maxNumber = parseInt(scope.maxNumber, 10);
     var curNumber = scope.currentPage; //当前页数
     var transformedInput = viewValue.replace(/[^0-9]/g, '');
     if (transformedInput !== viewValue||parseInt(transformedInput,10)<1||parseInt(transformedInput,10)>maxNumber) {
      ctrl.$setViewValue(curNumber);
      ctrl.$render();
      return curNumber;
     }
     return viewValue;
    });
   }
  };
 }])
.directive('cusPagination',[function(){
  return {
   restrict: "E",
   templateUrl: 'views/template/pagination.html',
   scope: {
    numPerPage: "=numPerPage",
    totalItems: "=totalItems",
    currentPage: "=cusCurrentPage",
    perPageSize:"=perPageSize",
    inputCurPage:"=inputCurPage",
    maxPages:"=maxPages",
    pageChanged: "&pageChanged"
   },
   replace: false
  };
 }]);
