角度ui网格保存和恢复状态

Question

我需要知道如何在angularui网格中实现保存和恢复状态而不使用任何按钮.当我们在网格中进行任何更改时,我需要自动保存状态.我们还必须自动恢复已保存的状态.即使我们刷新页面,也应该恢复保存的状态

Answer 1

这是我想出来的.我无法找到网格状态更改的单个事件,但它看起来确实几乎所有内容都有单独的事件.这里有一些我正在使用的.我只是在onRegisterApi回调中设置一个断点,并挖掘gridApi对象来查找事件.http://plnkr.co/edit/LAMZvOkpx6jsD4CWSz04?p=preview

HTML:

<div ui-grid="gridOptions"
     ui-grid-selection 
     ui-grid-resize-columns 
     ui-grid-auto-resize 
     ui-grid-move-columns 
     ui-grid-grouping 
     ui-grid-save-state>
</div>

JS:

$scope.gridOptions = {
  data: [
    { name: 'Jack', title: 'manager', phone: '123456789', location: 'india'},
    { name: 'Suzy', title: 'developer', phone: '465189798', location: 'usa'},
    { name: 'George', title: 'secretary', phone: '82656517', location: 'japan'},
    { name: 'Michael', title: 'analyst', phone: '31321687', location: 'egypt'},
    { name: 'Sara', title: 'consultant', phone: '59595847', location: 'germany'},
    { name: 'Chris', title: 'engineer', phone: '789456123', location: 'russia'},
    { name: 'Elizabeth', title: 'clerk', phone: '963852741', location: 'china'},
    { name: 'Jane', title: 'intern', phone: '147258369', location: 'australia'},
    { name: 'Bill', title: 'accountant', phone: '951487623', location: 'brazil'}
  ],
  columnDefs: [
    { name: 'name' },
    { name: 'title' },
    { name: 'phone' },
    { name: 'location' }
  ],
  enableGridMenu: true,
  enableRowSelection: true,
  enableRowHeaderSelection: false,
  enableColumnResizing: true,
  enableColumnReordering: true,
  enableFiltering: true,
  onRegisterApi: function(gridApi) {
    // Keep a reference to the gridApi.
    $scope.gridApi = gridApi;

    // Setup events so we're notified when grid state changes.
    $scope.gridApi.colMovable.on.columnPositionChanged($scope, saveState);
    $scope.gridApi.colResizable.on.columnSizeChanged($scope, saveState);
    $scope.gridApi.grouping.on.aggregationChanged($scope, saveState);
    $scope.gridApi.grouping.on.groupingChanged($scope, saveState);
    $scope.gridApi.core.on.columnVisibilityChanged($scope, saveState);
    $scope.gridApi.core.on.filterChanged($scope, saveState);
    $scope.gridApi.core.on.sortChanged($scope, saveState);

    // Restore previously saved state.
    restoreState();
  }
};

function saveState() {
  var state = $scope.gridApi.saveState.save();
  localStorageService.set('gridState', state);
}

function restoreState() {
  $timeout(function() {
    var state = localStorageService.get('gridState');
    if (state) $scope.gridApi.saveState.restore($scope, state);
  });
}
