Question

这是我的代码

>>> import keyword
>>> keyword.iskeyword("pass")
True
>>> keyword.iskeyword("not_pass")
False

var app = angular.module('app', ['ngTouch', 'ui.grid']);

app.controller('MainCtrl', ['$scope', '$http', function ($scope, $http) {
  var today = new Date();
  $scope.gridOptions = {
    enableFiltering: false,
    onRegisterApi: function(gridApi){
      $scope.gridApi = gridApi;
      $scope.gridApi.grid.registerRowsProcessor( $scope.singleFilter, 200 );
    },
    columnDefs: [
      { field: 'name' },
      { field: 'gender', cellFilter: 'mapGender' },
      { field: 'company' },
      { field: 'email' },
      { field: 'phone' },
      { field: 'age' },
      { field: 'mixedDate' }
    ]
  };

  $http.get('https://cdn.rawgit.com/angular-ui/ui-grid.info/gh-pages/data/500_complex.json')
    .success(function(data) {
      $scope.gridOptions.data = data;
      $scope.gridOptions.data[0].age = -5;

      data.forEach( function addDates( row, index ){
        row.mixedDate = new Date();
        row.mixedDate.setDate(today.getDate() + ( index % 14 ) );
        row.gender = row.gender==='male' ? '1' : '2';
      });
    });
    
  $scope.filter = function() {
    $scope.gridApi.grid.refresh();
  };
    
  $scope.singleFilter = function( renderableRows ){
    var matcher = new RegExp($scope.filterValue);
    renderableRows.forEach( function( row ) {
      var match = false;
      [ 'name', 'company', 'email' ].forEach(function( field ){
        if ( row.entity[field].match(matcher) ){
          match = true;
        }
      });
      if ( !match ){
        row.visible = false;
      }
    });
    return renderableRows;
  };
}])
.filter('mapGender', function() {
  var genderHash = {
    1: 'male',
    2: 'female'
  };

  return function(input) {
    if (!input){
      return '';
    } else {
      return genderHash[input];
    }
  };
});

在上面的代码中，第一个ui-grid结构显示然后数据将绑定到ui-grid，但我想在加载数据后显示整个网格结构。这是我的傻瓜http://plnkr.co/edit/?p=preview

一种流行的设计是在数据尚未加载时显示加载状态，为此，您可以添加dataLoaded标志来控制网格何时就绪，将标志设置为true in $http.get的成功回调。见下文：

$scope.dataLoaded = false;
$http.get('https://cdn.rawgit.com/angular-ui/ui-grid.info/gh-pages/data/500_complex.json').success(function(data) {
  // ...
  $scope.dataLoaded = true;
});

在您的模板中，它可以是：

<div id="grid1" ui-grid="gridOptions" class="grid" ng-show="dataLoaded"></div>
<div ng-hide="dataLoaded">Loading...</div>

数据从服务获取后如何显示Ui-grid？
