Question

我是MEAN堆栈应用程序的新手，所以我要求帮助每次AngularJS尝试解析以下代码

<button type="button" class="btn btn-link pull-right" ng-click="delete({{ post._id }});"><span class="glyphicon glyphicon-trash"></span></button>

在控制台中显示以下错误：

Error: [$parse:syntax] http://errors.angularjs.org/1.4.3/$parse/syntax?p0=%7B&p1=invalid%20key&p2=9&p3=delete(%7B%7B%20post._id%20%7D%7D)%3B&p4=%7B%20post._id%20%7D%7D)%3B

但是当我检查删除按钮时，我可以找到：

    <button type="button" class="btn btn-link pull-right" ng-click="delete(55ba1c2d6411b92c1715490c);"><span class="glyphicon glyphicon-trash"></span></button>

有人可以帮我解决这个问题吗？

从ng-click属性中删除{{ }}，在这种情况下不需要：

ng-click="delete(post._id);"

为什么？

https://docs.angularjs.org/api/ng/directive/ngClick

ng-click指令接受一个在点击时评估的表达式。
