Question

I have a cycle that it’s just working for my last element. It was suposed to work for each element.

for (var z=1; z<$('.page').length;z++){ 

$('#arrowUp_'+z).click(function(){
        $('#thumbsContainer_'+z).animate({top: '-='+93+'px'}, {duration: 1000});
        cont++;
        arrowThumbs();
    });

    $('#arrowDown_'+z).click(function(){
        $('#thumbsContainer_'+z).animate({top: '+='+93+'px'}, {duration: 1000});
        cont--;
        arrowThumbs();
    });
}

If I replace z for one number I can make it working for that case. But I don´t want to repeat the same process N time. So I thought it was good idea to make a a cycle for…but no success

Can anyone explain how to do that??
Thanks

Answer 1

Why are you using IDs? why can’t you just add a class on each element like so

<div id="arrowUp_1" class="arrowUp">

</div>

$('.arrowUp').click(function(){...});

also [things you should know]

‘-=’+93+’px’ its pointless you can have ‘-=93px’ still be the same thing as it would be consider as a string not a number its just like saying var h3ll0; is not a string 🙂

cont++ is not predefined before and your whole don’t work because animate() is wrong…
click the link so u can get some help with it http://api.jquery.com/animate/

you do not put {duration:1000} just put 1000 as that is an attribute on its own and expects a number [of milliseconds not a json object]…

UPDATE
check this code…

==============================================

CSS:

span {background: red;position: absolute; left: 0;}

JS

$(function() {
    $('div').click(function() {
        $('p').append($(this).text());
        //alert('text');
        var i = $(this).index($('ul div'));
        console.log($(this));
        $('ul span').eq(i).animate({
            left: '50%'
        }, 1000);
    });
});

HTML

<p>Test...</p>
<hr />
<ul>
    <div>Click 1</div>
    <div>Click 2</div>
    <div id="b">Click 3</div>
    <div>Click 4</div>
</ul>
<br /><br /><br /><br />
<ul>
    <span>Im thumb 1</span>
    <span>Im thumb 2</span>
    <span>Im thumb 3</span>
    <span>Im thumb 4</span>
</ul>

This is a bad example of element choice 🙂 but its better solution for you 🙂 I should think 🙂
