是否可以将带有vars的json对象作为angularjs指令参数传递？

Question

here is how I am trying now:

<ul
    class="list"
    list query="
        {
            'people': [{'people.id': '+id_+' }],
                    }
                }" 
>
   <!-- ... -->

on the directive I do:

var query = scope.$eval(attrs.query);

but by logging this variable I can see that the '+id_+' variable is not 'replaced' it's value.

I know there are many other ways of achieving the same resilt, but I feel like this one would be the most dynamic for at least this situation.

Answer 1

You need to evaluate the the value of _id when you pass it in as an attribute: {{_id}} , see this plunk . However for the sake of readability I would avoid passing in Json objects like that into a directive, place that object on your controllers scope and pass that variable to the directive.
