arrays - 如何从数组 angularjs 中删除项目？

Question

为什么我无法从数组帖子中删除项目？

删除项目的html标签

html tag
<span ng-click="remove($index)"> delete</span>

//AngularJS method where I try to delete item
blog.remove = function(index) {
blog.posts.splice(index, 1);
};

//Angular array posts
blog.posts = [{
    "title": "Blog Post One",
    "comments": [
      {
        "body":"Lorem ipsum dolor sit amet, consectetur adipisicing elit. ",
        "author": "trollguy87"
      }
    ]}];

哪里可能有问题？

Answer 1

尝试将项目传递给函数并从项目中获取索引。

正如下面的线程中提到的。
