如何创建“<a>` link if something is true?

Question

I know this question sounds redundant but I'm learning angular and would it be possible to create a link if a condition met is true or would I just have to do all the work on the front end?

  $scope.no_animal_number = function('animalnumber'){
      var noassignednumber;    
      if(noassignednumber == ''){
        noassignednumber = "{{ l.animaltype }}";
      }if(nocode == 'animalnumber')
        nocode = "<a href="site.php?site={{ l.animalnumber }}">{{ l.animaltype }}</a>";
    }
return noassignednumber;
}

 <tr ng-repeat="l in animal_list">
    <td>{{ l.animalnumber }}</td>
    <td>{{ no_animal_number(l.animaltype) }}</td>
 </tr>

this was my attempt at creating a function to do this.

你的问题有点令人困惑，因为你是从你的视图中调用一个函数，但是你在控制器上创建该函数的方式看起来不会起作用。

以下是我推荐的内容（或根据您的具体需求进行类似）：

<tr ng-repeat="l in animal_list">
    <td>{{l.animalnumber}}</td>
    <td>
        <span ng-if="l.animalnumber">{{l.animaltype}}</span>
        <span ng-if="!l.animalnumber">
            <a href="site.php?site={{l.animaltype}}">{{l.animaltype}}</a>
        </span>
    </td>
</tr>
