How to get ID of clicked element with jQuery

Question

I have the following html:

<a href="#" id="#1" class="pagerlink" >link</a>
<a href="#" id="#3" class="pagerlink" >link</a>
<a href="#" id="#2" class="pagerlink" >link</a>
/*etc.... */

and the following jQuery script:

$(document).ready(function() {

    var $container = $('.gallery_r').cycle({ 
        fx:     'scrollHorz', 
        speed:   500, 
        timeout: 0 
    }); 

    $('a.pagerlink').click(function() { 
        var id = $(this).attr('id');
        $container.cycle(id); 
        return false; 
    }); 

});

the 'pagerlink' links control are to jQuery Cycle slideshow. If I swap this line:

$container.cycle(id); 

for this

$container.cycle(7); 

it works... (obviously only navigating to slide number 7). So, my question is how can I pick up the ID of the link being clicked and pass it into that line?

Thanks in advance!

Answer 1

Your IDs are #1, and cycle just wants a number passed to it. You need to remove the # before calling cycle.

$('a.pagerlink').click(function() { 
    var id = $(this).attr('id');
    $container.cycle(id.replace('#', '')); 
    return false; 
});

Also, IDs shouldn't contain the # character, it's invalid (numeric IDs are also invalid). I suggest changing the ID to something like pager_1.

<a href="#" id="pager_1" class="pagerlink" >link</a>

$('a.pagerlink').click(function() { 
    var id = $(this).attr('id');
    $container.cycle(id.replace('pager_', '')); 
    return false; 
});

You just need to remove the hash from the beginning:

$('a.pagerlink').click(function() { 
    var id = $(this).attr('id').substring(1);
    $container.cycle(id); 
    return false; 
});

@Adam Just add a function using onClick="getId()"

function getId(){console.log(this.event.target.id)}
