這裏是角度新手。我正在嘗試Brian's example of importing data into UI Grid from Excel。這像一個魅力。 Brian使用自定義指令。我能夠完美地讀取excel文件。在讀取指令中的excel數據後,我想用控制器中現有的UI網格表檢查excel數據列。確認所有列都存在於Excel中後,我需要將其保存在我的數據庫中。在指令中使用控制器
爲此,我無法從指令中訪問gridApi。不知道我出錯的地方。任何幫助,高度讚賞!提前致謝!
下面是代碼的簡化版本,它只是在指令中記錄了GridApi /任何Scope變量(來自控制器)。
app.js
var crApp_WCF = angular.module('crApp_WCF', ['ngRoute', 'crApp_WCF_Ctrls', 'crServices', 'ui.grid', 'crApp_WCF_Drtvs', 'ui.grid.edit', 'ui.grid.exporter', 'ui.grid.selection']);
controller.js
var crApp_WCF_Ctrls = angular.module('crApp_WCF_Ctrls', ['crServices', 'ui.grid.exporter']);
crApp_WCF_Ctrls.controller('crHomeCtrl', function ($scope,$rootScope, $http, uiGridConstants, CrCRUD, uiGridExporterService, uiGridExporterConstants) {
$scope.crGrid = {
$scope.crGrid.onRegisterApi = function (gridApi) {
columnDefs: [
{ name: 'OppName', field: 'OppName', enableFiltering: false, minWidth: 100, headerTooltip: true, enableCellEdit: false },
{ name: 'AcCode', field: 'AcCode', enableFiltering: false, minWidth: 60, headerTooltip: true, enableCellEdit: false },
]}
$scope.gridApi = gridApi;
};
directives.js
var crApp_WCF_Drtvs = angular.module('crApp_WCF_Drtvs', ['crApp_WCF_Ctrls']);
crApp_WCF_Drtvs.directive("fileread", [function() {
return {
controller: 'crHomeCtrl',
scope: {
gridApi: '='
},
link: function ($scope, $elm, $attrs, $rootScope) {
$elm.on('change', function (changeEvent) {
Console.log(($scope.gridApi) //displays Undefined; I want the gridApi from the controller to be displayed here.
});
}
}
}]);
Index.html
<div ng-controller="crHomeCtrl">
<form class="form-inline">
<button type="button" class="btn btn-success" ng-click="exportXLSX()">Export as XLSX</button>
<button type="button" class="btn btn-success" ng-click="showImport=true">Import from excel</button>
<button type="button" class="btn" ng-click="showImport=false" ng-show="showImport">Close</button>
<br />
<br />
<div ui-grid="crGrid" ui-grid-edit ui-grid-exporter ui-grid-selection class="CrGrid">
<div class="grid-msg-overlay" ng-show="showImport">
<div class="msg">

<br />

謝謝@masterpreenz!我用你的第二個解決方案。而不是gridapi,我使用opts,它的工作。我必須將opts =「vm.gridOptions」更改爲opts =「crGrid」才能使其正常工作。那是我出錯的地方! :) – Linda
