AngularJS纳克级过滤器不工作

Question

我有我的纳克级的简单过滤器，寻找一个摆脱，随着服务业务的我NG重复“1A”

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

如果RID开始始于1A那么类couldBeWrong的应该应用

我也曾尝试各种变化如

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

和

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

编辑：基于公认的答案，这里是我的解决方案

加入到控制器

$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 
    } 
} 

，并在重复的NG-CLASS

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

Answer 1

试试这个

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

In Controller

$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 
    } 
} 

Answer 2

你似乎忘记了大括号。它应该是这样的：

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