How to dynamically configure ng-grid

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.

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.

回答5:

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.
