Javascript 为什么ng if不在ng内部工作重复

如果在ng内重复，我无法正确使用ng。我已将AngularJS更新为2014年9月27日的最新版本，但仍然无法正常运行。在ng repeat之外，我有一些代码可以正常工作，在ng if=vm.detail==false时，我也有一些代码可以在ng repeat fine内部工作。但是，ng if=vm.detail==true不起作用。我甚至已经将vm.detail的值打印到了控制台上，它是正确的，应该是正确的。但是，将ng if=vm.detail==true计算为true的代码块不会执行。这是胡说八道。这是我的密码：

把引语从事实上去掉怎么样？我试过了。我把它们放在单引号里，看看是否有区别。我没有找到。但是，好问题。太多的代码无法放入Fiddler。但是，我确实知道ng if='vm.detail==true | | vm.detail==null'确实有效。对我来说，某处有一个空值。然而，控制台上说的是不同的。这可能只是我的DOM的控制流问题吗？这里：更改为td>{{info.TrusteeCustNum}…@user1789573不客气。我将添加答案，也许这对将来的其他人有帮助基本上，如果ng repeat中的别名与$scope的属性同名，您将尝试访问Javascript，但会在访问过程中出错。IMHO，这是谷歌AngularJS团队应该解决的控制流问题。谷歌注意：请相应地更新你的资料。
