使用jquery for循环获取值

Question

I have several item in a databse, I'm displaying a link with in the href the id of each item.

So I want to get the id from a href which is in a PHP while loop. So I did a for loop to do it but it seems to only get the first href attr.

for (var i = 0; i < check; i++) 
{
   var id = $(".id").attr('href');
   console.log(id);
} 

Check is equal to the number of columns in the database depends of a special id. In this case check = 3

The link is: echo '<a id="dislike" class="btn-primary btn pull-right id" href="'.$items['id'].'">Dislike</a>';

Any idea of why it doesn't work ?

I got them all!

But how can I make them go out of the function ?

function checkingfetchresult(userid){

    $.post("ajax/checkingfetchresult.php", { userid: userid },
            function(check){
            $(".id").each(function(){
                var id = $(this).attr('href');
            });

    });

}

You are selecting the same elements on each iteration and then getting the attribute of the first element in the set. Instead of looping like that, you should use each:

$(".id").each(function(){
   var id = $(this).attr('href');
   console.log(id);
});
