Question

我正在使用ui-grid到upload a XLS file through a directive and push the data

我正在尝试在我的指令和控制器之间移动数据（相当新的角度）。我经历了一堆线程（this，this，this和this），试图了解如何使用&，{{ 1}}，@，=和$watch，但我仍然不明白如何将数据从指令（具有JSON对象）移动到数组（myData）在我的控制器中。如果有人能帮我解决这个问题......

控制器

$observe

指令

.controller('ListCtrl', function ($scope, $state, $log, ServerRequest, $localStorage, $sessionStorage, uiGridConstants) {

        var vm = this, c = console;

        $scope.myData = [

在你的指令中，声明对myData的引用（可以是任何名称）：

scope: {
    myData: '=',
    opts: '='
}

指令用法（myData是控制器中的对象）：

<fileread my-data="myData"></fileread>

现在，控制器和指令中的$ scope / scope指向同一资源。

@用于单向数据绑定，因此您在评论中发布了错误。
