问题
I have a view in an angularjs application in which I want to allow the user to select between various differently configured grids. Ideally I would like to bind the value passed to the ng-grid directive to a model variable, as illustrated below. However, although this example renders markup that works when a simple string value is passed to ng-grid (ie. <div class="gridStyle" ng-grid="gridOptions1"></div>
, dynamic configuration fails.
var app = angular.module('myApp', ['ngGrid']);
app.controller('MyCtrl', function($scope) {
$scope.option;
$scope.myData = [{name: "Moroni", age: 50},
{name: "Tiancum", age: 43},
{name: "Jacob", age: 27},
{name: "Nephi", age: 29},
{name: "Enos", age: 34}];
$scope.gridOptions1 = { data: 'myData',
columnDefs: [{ field:"name", displayName: "NAME"},
{ field:"age", displayName: "AGE"}],
multiSelect: true };
$scope.gridOptions2 = { data: 'myData',
columnDefs: [{ field:"name", displayName: "Name"},
{ field:"age", displayName: "Age"}],
multiSelect: false };
});
<body ng-controller="MyCtrl">
<label>Show me:</label>
<input type="radio" name="option" ng-model="option" value="gridOptions1">Grid A</input>
<input type="radio" name="option" ng-model="option" value="gridOptions2">Grid B</input>
<div class="gridStyle" ng-grid="{{option}}"></div>
</body>
Can anyone tell me please if there is a way of getting ng-grid to accept a different configuration dynamically, or if there is a workaround to this limitation? Please note that I need to reconfigure multiple properties of the grid, not just the columnDefs
and data
properties for which I believe there are workarounds.

回答1:
It looks like you can do it if you assign columnDefs
to a string of a property on the $scope
and then change the array: http://plnkr.co/edit/wuob1M?p=preview;
It is described in this issue raised on ng-grid.
JS:
var app = angular.module('myApp', ['ngGrid']);
app.controller('MyCtrl', function($scope) {
$scope.myData = [{name: "Moroni", age: 50},
{name: "Tiancum", age: 43},
{name: "Jacob", age: 27},
{name: "Nephi", age: 29},
{name: "Enos", age: 34}];
$scope.columnDefs1 = [{ field:"name", displayName: "NAME"},
{ field:"age", displayName: "AGE"}];
$scope.columnDefs2 = [{ field:"name", displayName: "Name"},
{ field:"age", displayName: "Age"}];
$scope.gridOptions = { data: 'myData',
columnDefs: 'columnDefs1',
multiSelect: true };
$scope.switchColumnDefs = function() {
$scope.columnDefs1 = $scope.columnDefs2;
}
});
HTML:
<body ng-controller="MyCtrl">
<label>Show me:</label>
<a ng-click="switchColumnDefs()">Switch Options</a>
<div class="gridStyle" ng-grid="gridOptions"></div>
</body>

Just thought I'd share that if anyone is interested in changing from Single Select to MultiSelect it can be done dynamically like so:
$gridScope.selectionProvider.multi = true / false;

Found a nice solution to this on the angular forum. Essentially, if an array of config objects is maintained, individual elements can be passed to the ng-grid directive as in the markup above. Plunker illustrating solution here: http://plnkr.co/edit/TDGKRo?p=preview
var gridOptions1 = {
data: 'myData',
columnDefs: [
{ field:"name", displayName: "NAME"},
{ field:"age", displayName: "AGE"}],
multiSelect: true,
selectedItems: $scope.selected
};
var gridOptions2 = {
data: 'myData',
columnDefs: [
{ field:"name", displayName: "Name"},
{ field:"age", displayName: "Age"}],
multiSelect: false,
selectedItems: $scope.selected
};
$scope.filterTabs = [{grid: gridOptions1}, {grid: gridOptions2}];
<ol>
<li ng-repeat="tab in filterTabs">
<div class="gridStyle" ng-grid="tab.grid"></div>
</li>
</ol>

Another way to do this is to just stick in something like:
<div ng-grid="gridOptions" ng-if="refresh"></div>
Then just flip refresh to off, update the grid config, then back to on in two different refresh cycles.

It is possible like the plnker that I edited for you: Here
Please notice when I played with it, not all options where live refreshing... But some where as you can see in the example.
Basically the solution is to have $scope variables assigned to the params of gridOptions.
