将变量传递到角度过滤器

Question

I'm writing an Angular app with some dynamic pages. I've got a stateParam named currentCategory which gives back an integer for current category's id. Is there a way to pass this integer into an Angular filter, since I only want to show current page's category?

This would be straightforward, but returns an syntax error.

<div ng-repeat="category in categories | filter:{cat_id:{{currentCategory}}}:true">

Answer 1

删除插值表达式（ {{ }} ），它应该可以工作：

filter:{cat_id:currentCategory}:true
