Question

嘿伙计们我有拖曳json数组的对象。它们包含这样的属性对象1：

    $scope.list01 = [
           {
               "key":"00.00","value":"1"
           },{
               "key":"00.15","value":"1.3"
           },{
               "key":"00.30","value":"1.8"
           },{
               "key":"00.45","value":"1.9"
           },{
               "key":"01.00","value":"4"
           },{
               "key":"01.15","value":"3"
           },{
               "key":"01.30","value":"7.5"
           },{
               "key":"01.45","value":"0"
           },{
               "key":"02.00","value":"22.3"
           }];

和另一个json对象

   $scope.list02 = [
           {
               "key":"00.00","value":"1"
           },{
               "key":"00.15","value":"1.3"
           },{
               "key":"00.30","value":"1.8"
           },{
               "key":"00.45","value":"1.9"
           },{
               "key":"01.00","value":"0"
           },{
               "key":"01.15","value":"13"
           },{
               "key":"01.30","value":"13"
           },{
               "key":"01.45","value":"13"
           },{
               "key":"02.00","value":"28"
           }
       ];

我想比较两个对象并在新数组中显示不同的值我使用像这样的角度过滤器

        .filter("different",function(){
           return function(input,compares){
               var newArray = [];

               for(i=0;i<input.length;i++){
                   var foundMatch = false;
                   for(j=0;j<compares.length;j++){
                       if(compares[j].value == input[i].value ){
                          foundMatch = true;
                           newArray.push({
                               value:input[i].value,
                               key:input[i].key

                           })
                           compares[j]++;
                           break;
                       }
                   }
                   if(!foundMatch){
                       newArray.push({
                           value:input[i].value,
                           key:input[i].key

                       })
                   }
               }

               return newArray;
           }
       });

并像我这样在我的DOM上使用过滤器

{{compare | differentvalue:filterer}}

问题是输出不包含零值。过滤器没有获得0值，我将0更改为“0”，过滤器正常工作。关于如何解决这个问题的任何想法？

Angularjs不计算0的假值
