angularjs表格ng-table使用备忘录

时间:2020-05-15 彼岸花在开人气:0

项目中用到angularjs的表格ng-table，功能相当强大，像搜索、排序、checkbox、分页、每页表格显示数目等都有。API，demo什么的也只能参考官网了。这里做个备忘，哪天肯定还会用到。

  <table ng-table="tableParams" show-filter="true" class="table">
    <tr ng-repeat="user in $data" ng-class="{ 'emphasis': user.money > 500 }">
      <td width="30" style="text-align: left" header="'ng-table/headers/checkbox.html'">
        <input type="checkbox" ng-model="checkboxes.items[user.organizationId]" />
      </td>
      <td data-title="'编号'" sortable="'organizationId'">
        {{user.organizationId}}
      </td>
      <td data-title="'名称'" sortable="'name'">
        {{user.name}}
      </td>
    </tr>
  </table>
  <script type="text/ng-template" id="ng-table/headers/checkbox.html">
    <input type="checkbox" ng-model="checkboxes.checked" id="select_all" name="filter-checkbox" value="" />
  </script>

</body>
</html>

js：

var app = angular.module('main', ['ngTable']).
controller('DemoCtrl', function($scope, ngTableParams, NameService) {

  var data = NameService.data;

  $scope.tableParams = new ngTableParams(
   {
    page: 1,      // show first page
    count: 10,      // count per page
    sorting: {name:'asc'}
   },
   {
    total: 0, // length of data
    getData: function($defer, params) {
     NameService.getData($defer,params,$scope.filter);
    }
  });
  
  $scope.$watch("filter.$", function () {
    $scope.tableParams.reload();
  });
  
});

app.service("NameService", function($http, $filter){
 
 function filterData(data, filter){
  return $filter('filter')(data, filter);
 }
 
 function orderData(data, params){
  return params.sorting() ? $filter('orderBy')(data, params.orderBy()) : filteredData;
 }
 
 function sliceData(data, params){
  return data.slice((params.page() - 1) * params.count(), params.page() * params.count())
 }
 
 function transformData(data,filter,params){
  return sliceData( orderData( filterData(data,filter), params ), params);
 }
 
 var service = {
  cachedData:[],
  getData:function($defer, params, filter){
   if(service.cachedData.length>0){
    console.log("using cached data")
    var filteredData = filterData(service.cachedData,filter);
    var transformedData = sliceData(orderData(filteredData,params),params);
    params.total(filteredData.length)
    $defer.resolve(transformedData);
   }
   else{
    console.log("fetching data")
    $http.get("data.json").success(function(resp)
    {
     angular.copy(resp,service.cachedData)
     params.total(resp.length)
     var filteredData = $filter('filter')(resp, filter);
     var transformedData = transformData(resp,filter,params)
     
     $defer.resolve(transformedData);
    }); 
   }
   
  }
 };
 return service; 
});

json数据：
