Question

Just a simple question about jQuery. I’m new at it. How would I get the value for “post_id” when the users clicks on “span.fav” (the star)? I want the parent’s value, not the first one in the document. I think closest will work?

the html

<form action="index.php" method="post" accept-charset="utf-8"> 
    <div class="hidden"> 
        <input type="hidden" name="post_id" value="1000000019" />
        <input type="hidden" name="xxxxxxx" value="xxxxxxxxxx" />
    </div>
    <p>
        <span name="fav" class="fav">★</span>Post message here...<span class="author">by Thomas Quantas</span>
    </p>
</form>
<form action="index.php" method="post" accept-charset="utf-8"> 
    <div class="hidden"> 
        <input type="hidden" name="post_id" value="1000000020" />
        <input type="hidden" name="xxxxxxx" value="xxxxxxxxxx" />
    </div>
    <p>
        <span name="fav" class="fav">★</span>Post message here...<span class="author">by Thomas Quantas</span>
    </p>
</form>

the jQuery I have so far.

$(document).ready(function(){
$("span.fav").bind('click', function() {
    //var test = $(this).parent();
    //var test = $(this).closest();
    var hidden_id = $(this).closest($("input[type='hidden']").attr('value'));
    var hidden_id = $("input[type='hidden']").attr('value');
    alert(hidden_id);
});
});

Try:

    var hidden_value = $(this).closest('form').find('input:hidden[name="post_id"]').attr('value');
    alert(hidden_value);

The difference is inside closest: pass a string instead of jQuery selector.
