AngularJS Question

Angular-grid when using $http to load json data

I am using ag-grid plugin in a project. I get json data using $http service. But the grid shows blank in web page. But when json data is applied directly, grid works. I think this is probably due to delay in getting the data from $http. But as per angular concept, the grid should be updated when data comes. Is there any solution to show the html page only when data comes from the server.

Below is my javascript file 'fileBrowser.js':

var fileBrowserModule = angular.module('fileBrowser', ['agGrid']);

fileBrowserModule.controller('fileBrowserController', function($scope, $http) {

$scope.rowData=[
];

$http.get("http://localhost:8080/KKR/flow/sin/allSins.json")
.success(function(data) {


$scope.rowData=JSON.parse("["+JSON.stringify(data)+"]");
console.log($scope.rowData);
});



/*
$scope.rowData=[
{"group":true,"data":{"name":"joe"},
"children":[
{"group":true,"data":{"name":"pat"},
"children":[{"group":true,
"data":{"name":"maya"},
"children":[{"group":false,
"data":{"name":"brook"},
"children":[]},{"group":true,
"data":{"name":"kery"},
"children":[{"group":false,
"data":{"name":"santosh"},
"children":[]}]}]}]},
{"group":false,
"data":{"name":"aravind"},"children":[]}]}
]
*/


var columnDefs = [
{headerName: "Name", field: "name", width: 250,
cellRenderer: {
renderer: 'group',
innerRenderer: innerCellRenderer
}},
{headerName: "Size", field: "size", width: 70, cellStyle: sizeCellStyle},
{headerName: "Type", field: "type", width: 150},
{headerName: "Date Modified", field: "dateModified", width: 150}
];

$scope.gridOptions = {
columnDefs: columnDefs,
rowData: $scope.rowData,
rowSelection: 'multiple',
rowsAlreadyGrouped: true,
enableColResize: true,
enableSorting: true,
rowHeight: 20,
icons: {
groupExpanded: '<i class="fa fa-minus-square-o"/>',
groupContracted: '<i class="fa fa-plus-square-o"/>'
},
onRowClicked: rowClicked
};

$scope.selectedFile = 'Select a file below...';



function rowClicked(params) {
var node = params.node;
var path = node.data.name;
while (node.parent) {
node = node.parent;
path = node.data.name + '\\' + path;
}
$scope.selectedFile = path;
}

function sizeCellStyle() {
return {'text-align': 'right'};
}

function innerCellRenderer(params) {
var image;
if (params.node.group) {
image = params.node.level === 0 ? 'disk' : 'folder';
} else {
image = 'file';
}
var imageFullUrl = '/example-file-browser/' + image + '.png';
return '<img src="'+imageFullUrl+'" style="padding-left: 4px;" /> ' + params.data.name;
}

});

Answer

Use the ag-Grid API for setting the row data.

Look at this example "Further Example Starting Point" to see.

Code is

$scope.gridOptions.api.setRows(res.data);
