jQuery inArray / indexOf始终返回-1

如何解决jQuery inArray / indexOf始终返回-1

So... I loaded json array trought Ajax,then I used $.each to put id values in an [] array.
Then I wanted to check if specific number that is in the variable exist in the array,so I tried using inArray and also indexOf in many different ways,tried changing to strings and integers,and nothing helped. I did waste few hours already at this... 

Here's my Ajax code:

    $.ajax({
           method: "POST",url: "loadost.php",dataType: 'json',data: {
               "id" : id
           },success: function(ostloaded){
     ostlength = ostloaded.length;
               $.each($(ostloaded),function(key,value){

我添加了“ loaded_id”以确保它是整数，但没有帮助。

                var loaded_id = parseInt(value.id);
                idArray.push(loaded_id);
     typ.push(value.typ);
            link.push(value.link);
           tyt_art.push(value.tytul_autor);
         
           });
           

在这里我排序应该在何时何地创建元素

           for(q = 0; q<=ostlength;q++){
           if(typ[q] == 1){
         $('<li class="op'+q+'"></li>').appendTo('body #ops');
         $('<div/>').text(tyt_art[q]).appendTo('body .op'+q);
       }
       if(typ[q] == 2){
         $('<li class="ed'+q+'"></li>').appendTo('body #eds');
         $('<div/>').text(tyt_art[q]).appendTo('body .ed'+q);
       }
       if(typ[q] == 3){
         $('<li class="ins'+q+'"></li>').appendTo('body #ins');
         $('<div/>').text(tyt_art[q]).appendTo('body .ins'+q);
       }

然后我创建播放列表

       unflist.push(link[q]);
           }  
           list = unflist.filter(function (el) {
  return el != null;
});
           loadsongs(0,list);
           $(".playerHs").html(tyt_art[0]);
       }
       
    });



console.log($.inArray(pageId,idArray),idArray.indexOf(pageId),pageId,idArray);

输出无论如何-永远不会改变，总是这样：Console Log

我更改了变量的名称，以使它们更清晰。
