Question

1）我有索引页面列表＆amp;编辑链接。编辑表单在同一个html中，但最初编辑＆＃39; div＆＃39; div是隐藏的。
2）我的控制器加载商品清单＆amp;显示记录和编辑链接。单击编辑链接转到控制器代码，获取单个记录并返回一个对象 3）我用新返回的对象更新我的$ scope.offer。然后我会显示编辑＆＃39; div＆＃39; div （作为模态）。我期望的是我的编辑表单显示默认值。但看起来好像没有绑定，我在编辑页面上没有任何价值。

我最近两天都在挣扎。我试过$ apply / $ digest，但是我收到了错误。我的理解是角度是2路绑定。但是在加载页面后，我无法在模态窗口中绑定变量。

非常感谢任何帮助。

提前致谢

Answer 1

解决了我自己的问题。这是一个非常小的错误，但从未实现过。我需要初始化我的'优惠'。

我修改的编辑功能如下：

$scope.Offer=new Offer();
....

$scope.editOffer = function (offerPassed) {
    $scope.Offer.$get({action:"get",id:offerPassed._id},function (Offer) {
        $('#show_offer_form_edit').toggleEditOfferForm();
    });
};

在angular.js中页面加载后的Angular 2路绑定
