我在项目中使用 ag-grid 插件。我使用 $http 服务获取 json 数据。但是网格在网页中显示为空白。但是当直接应用 json 数据时，grid 可以工作。我认为这可能是由于从 $http 获取数据的延迟。但是根据角度概念，网格应该在数据到来时更新。是否有任何解决方案仅在数据来自服务器时才显示 html 页面。

下面是我的javascript文件'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;
    }

});

使用 ag-Grid API 来设置行数据。

看这个例子“进一步的例子起点”看看。

代码是

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

我已经修改了以前的答案。而不是setRows我们可以使用setRowData. 这对我有用：

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