Jquery add Unique identifier to Function

I'm using the jQuery cycle plugin. However I need to add multiple instances of said code on a page. This will be passed through a loop. This means I have to add a unique identifier to the function. I'm really not that comfortable with JavaScript in general.

Below is the original code.

jQuery.fn.cycle.updateActivePagerLink = function(pager, currSlideIndex) { 
    jQuery(pager).find('li').removeClass('mini-activeLI') 
        .filter('li:eq('+currSlideIndex+')').addClass('mini-activeLI'); 
}; 

This is what I was trying. Where +unique+ could be generated by PHP 开发者_高级运维rand():

jQuery.fn.cycle.updateActivePagerLink = function(pager, currSlideIndex+unique+) { 
    jQuery(pager).find('li').removeClass('mini-activeLI') 
        .filter('li:eq('+currSlideIndex+unique++')').addClass('mini-activeLI'); 
}; 

Any assistance would be appreciated.

If you're confused about how to get a variable from PHP to Javascript, you can do something like:

<?php 
    $unique = 123456;
    echo "<script>var unique = $unique;</script>";
?>

Which will give you a global variable you can use from inside other script tags just fine.

Try this:

function(pager, currSlideIndex<?php echo $id ?>) { 
    jQuery(pager).find('li').removeClass('mini-activeLI') 
        .filter('li:eq('+currSlideIndex<?php echo $id ?>+')').addClass('mini-activeLI'); 
}; 

Edit: to pass it as variable have this:

<?php echo "<script type='text/javascript'>var _sliderIndexId = " + $id + ";</script>" ?>

And then:

function(pager, currSlideIndex) { 
        jQuery(pager).find('li').removeClass('mini-activeLI') 
            .filter('li:eq(' + (currSlideIndex + "") + (_sliderIndexId + "")) +')').addClass('mini-activeLI'); 
    };

Not sure about the PHP syntax but that's the general idea: have PHP output the id as global JS variable then use that variable in the function.
