javascript - jQuery generate unique IDs

Question

Here's what I have:

<a href="<?=$arItem["LINK"]?>"><?=$arItem["TEXT"]?></a>

It's a PHP array, which contains some links. I need to add an extra hash parameter #nav-link to the end of each link.

Here's how I tried do it:

<a id="likeLink" href=""><?=$arItem["TEXT"]?></a>
<script>
    $(document).ready(function () {
        $("#likeLink").attr("href", <?=$arItem["LINK"]?> + "#nav-link");
    });
</script>

But this code doesn't work because jQuery will not know which links I am linking to. So I guess that I need to generate the unique ids, but don't know how to do it.

Answer 1

I didn't need a forever unique/random id, just something that was unique per page, and all of these solutions seemed overkill for me so I came up with this:

var uniqId = (function(){
    var i=0;
    return function() {
        return i++;
    }
})();
