Question

此代码在JSFiddle中完美运行：

var app = angular.module('app', []);

app.filter('termsFilter', termsFilter);

function termsFilter(){
function parseString(input){

 // console.log('input', input);

    return input.split(",");
}


function findIndex(valueToSearch, theArray, currentIndex) {

 // console.log('currentIndex', currentIndex);

    if (typeof(currentIndex) === 'undefined') currentIndex = '';

 // console.log('targetArray', theArray);   

    if(Array.isArray(theArray)) {

            for (var i = 0; i < theArray.length; i++) {

// console.log('is theArray[' + i + ']', theArray[i]);            
               if (theArray[i].title == valueToSearch) {
                   console.log('found one');
                   return true;
               }
            }
            return false;
    } 
}



return function (array, propertyString, target){
    if(target && typeof(target) !== 'undefined'){
        target = parseString(target);     
    }

  // console.log('target:' ,target);

    return _.filter(array, function(item){

       if(!target || typeof(target) === 'undefined'){
           return true;
       }

       var targetArray = item.terms[propertyString];
       var returnStatus = false; 

       angular.forEach(target, function(value, key){


 // console.log('=======================================');
 // console.log('item:' ,item);
 // console.log('value:' ,value);
 // console.log('---------------------------------------');


           if(findIndex(value, targetArray)) {
                returnStatus = true; 
           }

       });

 // console.log('item:' + item.id ,returnStatus); 

        return returnStatus;

    });
};


}

在这里工作小提琴：http://jsfiddle.net/earthman/ho16td1o/

但是当我尝试在我的应用程序中使用它时，我收到错误：
