非工作版本。移动点击一个按钮下的网格code。
Non working version. Moved the grid code under a button click.

获取错误： - 类型错误：无法设置属性gridDim未定义
Getting the error : - TypeError: Cannot set property 'gridDim' of undefined
推荐答案
在实例$ scope.gridOptions之前，您的NG-网格初始化，因为这样它会引发未定义的错误。另外，如果你编程更改$ scope属性，您可能需要使用$应用让你改变显示在模板。
Your ng-grid is initializing before you instantiate $scope.gridOptions, as as such it throws the undefined error. Also, if you change a $scope property programatically, you may need to use $apply to get your changes to display on the templates.
所以，你需要做的就是确保数据结构存在（即使它们是空的），并调用$申请时，启动的数据网格：
So what you need to do is make sure the data structures exist (even if they're empty) and call $apply when "starting" the data-grid:
app.controller('MyCtrl', function ($scope) {
$scope.myData = [];
$scope.gridOptions = { data: 'myData' };
$scope.LoadGrid = function () {
alert('');
$scope.myData = [{ name: "Moroni", age: 50 },
{ name: "Tiancum", age: 43 },
{ name: "Jacob", age: 27 },
{ name: "Nephi", age: 29 },
{ name: "Enos", age: 34}];
$scope.$apply();
}
});
