javascript - ng-click 参数未正确传递

Question

我将一个绑定(bind)参数传递给 ng-click 上的函数，如下所示:

<li ng-repeat="follwing in following.Users">
    <a href="" ng-click="unfollow({{follwing.ID}})">Un-follow</a>
</li>

这导致了以下错误:

Error: [$parse:syntax] Syntax Error: Token 'follwing.ID' is unexpected, expecting [:] at column 12 of the expression [unfollow({{follwing.ID}})] starting at [follwing.ID}})].
http://errors.angularjs.org/1.2.10/$parse/syntax?p0=follwing.ID&p1=is%20unexpected%2C%20expecting%20%5B%3A%5D&p2=12&p3=unfollow(%7B%7Bfollwing.ID%7D%7D)&p4=follwing.ID%7D%7D)
    at http://localhost/mb-www2015/js/angular.v1.2.10.js:78:12
    at Parser.throwError (http://localhost/mb-www2015/js/angular.v1.2.10.js:9884:11)
    at Parser.consume (http://localhost/mb-www2015/js/angular.v1.2.10.js:9921:12)

当我在 {{follwing.ID}} 周围添加单引号时，例如:

<a href="" ng-click="unfollow('{{follwing.ID}}')">Un-follow</a>

它按原样传递字符串 {{follwing.ID}}，而不是其值。

还需要将文本和调用函数从取消关注更改为关注。如何从取消关注功能中访问点击的 anchor 标记？

感谢您的帮助。

这应该足够了:

<li ng-repeat="follwing in following.Users">
    <a href="" ng-click="unfollow(following.ID)">Un-follow</a>
</li>

ng-click预计 expression
