How to hide column in ng grid

问题

here is my code:

index.html

<!DOCTYPE html>
<html ng-app="myApp">

<head>
  <meta charset="utf-8" />
  <title>AngularJS Plunker</title>
  <link rel="stylesheet" type="text/css" href="http://angular-ui.github.com/ng- grid/css/ng-grid.css" />

  <script type="text/javascript" src="http://angular-ui.github.com/ng-grid/lib/ng-grid.debug.js"></script>
  <script src="app.js"></script>
</head>

<body ng-controller="MyCtrl">
    <div class="gridStyle" ng-grid="gridOptions"></div>
    <div class="selectedItems">Selected ID:{{mySelections[0].id}}</div><br><br>

</body>

</html>

app.js

var app = angular.module('myApp', ['ngGrid']);
app.controller('MyCtrl', function($scope) {
  $scope.mySelections = [];
  $scope.myData = [{empno: 111, name: "Moroni", id: 1},
                   {empno: 222, name: "Tiancum", id: 2},
                   {empno: 333, name: "Jacob", id: 3},
                   {empno: 444, name: "Nephi", id: 4},
                   {empno: 555, name: "Akon", id: 5},
                   {empno: 666, name: "Enos", id: 6}];
  $scope.gridOptions = { 
    data: 'myData',
    selectedItems: $scope.mySelections,
    multiSelect: false
  };
});

Q1: I want to hide the id column in ng-grid. Q2: After hiding the id column, may I get the id value when I select some row? How can modify the code?

回答1:

Just add below lines to configuration and it will work

 columnDefs: [
            {field: 'empno', displayName: 'empno'},
            {field:'name', displayName:'name'}
        ]

回答2:

You can set visible: false right in the column definition:

$scope.gridOptions = { 
    data: 'myData',
    selectedItems: $scope.mySelections,
    multiSelect: false,
    columnDefs: [
        {field: 'empno', displayName: 'empno', visible:false},
        {field:'name', displayName:'name'}
    ]
};

回答3:

You can also hide the column dynamically by adding this code after you define the grid;

    var pos = $scope.gridOptions.columnDefs.map(function (e) { return e.field; }).indexOf('yourFieldName');
    if ($scope.basicAdmin || $scope.superAdmin)
        $scope.gridOptions.columnDefs[pos].visible = true;
    else
        $scope.gridOptions.columnDefs[pos].visible = false;

The angularjs grid array is $scope.gridOptions.columnDefs. Change the gridOptions to the name of your grid.

Replace "yourFieldName" with whatever field you are wanting to hide. Next, put whatever condition you want to test.

This took some time to figure out. Hopefully, it will save others some time.

回答4:

To hide particular column in AngularJS UI grid we can use visible: false property like as shown below.

columnDefs: [
{ field: 'userid', visible: false, displayName: 'UserId' },
{ field: 'username', displayName: 'UserName' },
{ field: 'branch', displayName: 'Education' }
]

If you want to check it in complete example you need to write the code like as shown below

<html ng-app="myApp">
<head>

<link rel="stylesheet" type="text/css" href="http://angular-ui.github.com/ng-grid/css/ng-grid.css" />

<script type="text/javascript" src="http://angular-ui.github.com/ng-grid/lib/ng-grid.debug.js"></script>
<style type="text/css">
.gridStyle {
border: 1px solid rgb(212,212,212);
width: 400px;
height: 210px
}
</style>
</head>
<body ng-controller="MyCtrl">
<div class="gridStyle" ng-grid="gridOptions"></div>
<script type="text/javascript">
var app = angular.module('myApp', ['ngGrid']);
app.controller('MyCtrl', function ($scope) {
$scope.mySelections = [];
$scope.myData = [{ userid: 1, username: "Anil Singh", branch:"B.tech" },
{ userid: 2, username: "Sunil", branch: "Msc" },
{ userid: 3, username: "Sushil", branch: "B.Tech" },
{ userid: 4, username: "Dilip", branch: "MBA" },
{ userid: 5, username: "Upendra", branch: "MD" },
{ userid: 6, username: "Reena", branch: "CA"}];
$scope.gridOptions = {
data: 'myData',
selectedItems: $scope.mySelections,
multiSelect: false,
columnDefs: [
           { field: 'userid', visible: false, displayName: 'UserId' },
           { field: 'username', displayName: 'UserName' },
           { field: 'branch', displayName: 'Education' } ]
};
});
</script>
</body>
</html>

We can use the following code after define the grid

 if ($rootScope.CanDelete == false && $rootScope.CanEdit == false)
     $scope.ConfigItemGrid.columnDefs[4].visible = false;
 else
     $scope.ConfigItemGrid.columnDefs[4].visible = true;

回答6:

Use "hide: true" attribute as below in Angular 2, working fine for me:

columnDefs = [
    { headerName: "Make", hide: true, field: "make", editable: true, filter: 'text'},
    { headerName: "Model", field: "model", filter: 'text'},
    {
        headerName: "Price",
        field: "price",
        filter: 'number',
        cellClass: 'rightJustify',
        cellRenderer: function (params: any) {
            return '$' + params.value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ","); //thanks http://stackoverflow.com/users/28324/elias-zamaria
        }
    }
];

回答7:

I suggest adding 'visible: false' to the column definitions. If you choose not to specify it in columnDefs, when you post the row back to whatever your backend is, you may null out that field. That's what I've experienced.
