Finding id of elements

Question

i have this bit of html. (Link at bottom)

Its output of php code for status updates, it has view comments and post comment link, the post comment link uses jquery to add a textarea and submit button below that status update. and the view comments shows the comments to that status update below that status update.

So i use php looping so there will be obviously more than 1 status updates at most times(depends on how much friends users have) so i cant have an element like 'textelement', i will need to have elements like 'textelement1' and 'textelement2' So i used php to add the id of the status update in the end of the links like _id so the element id becomes view_comments_1.

So i want to use jquery to find out which element has been clicked so that i can add a text box and show comments below the right status update instead of showing it below all status updates.

                }
            });
        });
    });

Please help me out :)

Answer 1

add a class to to action buttons and pass the comment id as data attribute like so:

<a class="commentBtn" href='' data-commentid="1">Comment</a>

and than you can read out the id easily with jquery:

$(".commentBtn").live("click",function(e){ var id = $(this).data('commentid'); e.preventDefault(); // do something with id… });

Answer 2

You know that html forms can send arrays, right?

<input type="text" name="textelement[]" value="First Element" /><br/>
<input type="text" name="textelement[]" value="Second Element" /><br/>

PHP Code:

foreach($_POST['textelement'] as $somethingSomething){
    echo $somethingSomething, "\n";
}

Prints out:

 First Element
 Second Element
