javascript - AngularJS ng 类过滤器不起作用

Question

我在我的 ng-class 上有一个简单的过滤器，它在我的 ng-repeat of services 中寻找以 '1A' 开头的 rid

ng-class="{'couldBeWrong':rid.indexOf('1A') > -1}"

如果 rid 以 1A 开头，则应应用 couldBeWrong 类

我也尝试过各种变体，例如

class="{'couldBeWrong':rid.indexOf('1A') > -1}"

和

ng-class="{'couldBeWrong':service.rid.indexOf('1A') > -1}"

编辑:根据接受的答案，这是我的解决方案

添加到 Controller

$scope.getClass = function(field){
    if(field.indexOf('1L') > -1){
        return true;//or you can modify as per your need
    }else{
        return false;//you can modify as per your need   
    }
}

和重复的NG级

ng-class="{'couldBeWrong':getClass(service.rid)}"

Answer 1

试试这个

ng-class="{'couldBeWrong':getClass(rid)}"

在 Controller 中

$scope.getClass = function(){
  if(rid.indexOf('1A') > -1){
    return true;//or you can modify as per your need
  }else{
    return false;//you can modify as per your need   
  }
}
