I have a paginator on my website, and I need add a button that allows show all results without pagination.

For the pagination, I have this script:

```
jQuery(function() 
{
    var items = $("article.inmueble");
    var numItems = items.length;
    var perPage = 5;

    items.slice(perPage).hide();

    jQuery("#paginador").pagination({
        items: numItems,
        itemsOnPage: perPage,
        cssStyle: 'light-theme',
        onPageClick: function(pageNumber) { 
            var showFrom = perPage * (pageNumber - 1);
            var showTo = showFrom + perPage;

            items.hide() 
                 .slice(showFrom, showTo).show();
        }
    });
});

```

This code is in `js/initialize_paginator.js`.

In my `index.php` I call this script:

```
<script type="text/javascript" src="js/initialize_paginator.js"></script>

```

And in this `index.php` I have a button:

```
<button class="btn btn-default btn-sm">Ver todo</button>

```

How I can do to, when click this button, change the `var perPage = 5;` to (for example) `var perPage = 999999999;` to show all results?
