Hey guys, 
I modified a script that i found on the web and and i'm trying to use it as a thumbnail gallery scroller (for lack of better words).
The problem i'm running into right now is that when i click either the left or the right buttons all of the boxes scroll. I'm trying to use the (this) "selector" but i'm having trouble figuring it out can someone perhaps help me a bit with this one? would be greatly appreciated.

 

Here's the html.

<div class="container">
<div class="arrowL"><img  src="left.png"    width:'20';
    height:'100'; />
</div>
<div class="arrowR"><img src="right.png"    width:'20';
    height:'100';/>
</div>
<div class="list-container">
    <div class='list'>
        <div class="item">
        </div>
            <div class="item">
        </div>
            <div class="item">
        </div>
            <div class="item">
        </div>
            <div class="item">
        </div>
            <div class="item">
        </div>
	</div>
</div> 
     
    </div>

The css.

.item{ background-color:#FFFFFF;
    width:120px;
    height:90px;
    margin:5px;
    float:left;
    position:relative;
}
 .container{
width:1000px;
height:100px;
}
.list-container { 
display:inline-block;
overflow:hidden;    
width: 960px;  
float:left;    
}
.list{
    background:grey;
min-width:1500px;
    float:left;
}
.arrowR{
    width:20px;
    height:100px;
    float:right;
    cursor:pointer;
	opacity:0.5;
}
.arrowL{
    width:20px;
    height:100px;
    float:left;
    cursor:pointer;
opacity:0.5;
}

And the js.

<script>
$(document).ready(function() {

    var $item = $('div.item'),
        visible = 7,
        index = 0, 
        endIndex = ( $item.length / visible ) - 1; 

    $('div.arrowR').click(function(){
        if(index < endIndex ){
          index++;
          $item.animate({'left':'-=300px'});
        }
    });

    $('div.arrowL').click(function(){
        if(index > 0){
          index--;            
          $item.animate({'left':'+=300px'});
        }
    });
});
</script>

Anyone know what i'm doing wrong?

Simple mathematic, in that case if endIndex = ( $item.length / visible ) - 1 the result should be a signed integer (negative number).

 

So, use (*) instead (/)  - endIndex = ( $item.length * visible ) - 1 and try again.

Hey newhip,

 

the entindex is equal to "(6 / 7) -1", so you will get a negative number as a result and that statement has never been executed - if(index < endIndex ) b/s the index is set to zero!

 

I don't know what exactly your code is doing but after a quick check yesterday night I saw that error.

 

PS: A nice cat, I have a one which weights 15 pounds :)
