Change Javascript to search for text as oppose to numbers

Bit new to this, so please excuse me. Below is some JS I have started with as a template which works. If a number in the inventoryLevel string shows above one, it will display an in stock message, styled nicely.

<script type="text/javascript">
            $(document).ajaxComplete(function(event,request, settings) {
            var inventoryLevel = $(".InventoryLevel .VariationProductInventory").text();
  [B]          if(parseInt(inventoryLevel) >= "0") {[/B]
            $(".InventoryLevel .VariationProductInventory").html("<p style='font-family='Open Sans',Arial,Helvetica,sans-serif; font-size='13px'; font-weight='600'; font-color='#000'><img align='left' src='/product_images/uploaded_images/productcheck.jpg' alt='' /> Confirmed as <u>In Stock</u></p>");

Can anyone please tell me how I can change the above to search for “Sold Out” instead of a number? It’s something I need to change in the bolded bit above but I don’t know what do.

Any help would be greatly appreciated.

Thank you very much.

Issue solved by just adding an else statement under the above JS!
