    <p>I am trying to grab a query string parameter and match it to an array that is getting dynamically generated. </p> <p><em>Edit for clarity</em> The url will be something like www.example.com?some=stuff&amp;id=dynamicNumber</p> <p>I'm outputting my array from liquid (shopify) which seems to be rendering properly when I view the source.</p> <p>My failing point seems to be setting the actual variable "soldOut", because if I put one of the actual values that I know will be in the array, it returns true. </p> <p>Fiddle with a static array and functional matching: <a href="http://jsfiddle.net/zHuDU/5/" rel="nofollow">http://jsfiddle.net/zHuDU/5/</a></p> <p>I'm just missing the querystring function because I wasn't sure how to do that with JSfiddle</p> <p>Here is my code:</p> <pre><code>&lt;script&gt; var testArray = [ // shopify liquid to generate values {% for variant in product.variants %} {% if variant.inventory_quantity == 0 %} {{ variant.id }}, {% else %} {% endif %} {% endfor %} ]; function GetQueryStringParams(sParam) { var sPageURL = window.location.search.substring(1); var sURLVariables = sPageURL.split('&amp;'); for (var i = 0; i &lt; sURLVariables.length; i++) { var sParameterName = sURLVariables[i].split('='); if (sParameterName[0] == sParam) { return sParameterName[1]; } } } var soldOut = GetQueryStringParams('id'); if(jQuery.inArray(soldOut, testArray)!==-1) { console.log("The ID was in the test array (out of stock)"); } else{ console.log("The ID wasn't in the test array (so it's in stock or I messed up)"); } &lt;/script&gt; </code></pre>

    1. COSo it doesn't return false when not in the array? because the fiddle works just fine. Can you show us some examples of `GetQueryStringParams('id')`?

    2. COYes, the fiddle works, but when I try all the code together, it looks like GetQueryStringParams('id') isn't actually pulling the relevant info from the query string. That's what I was trying to say. I got it from here: http://css-tricks.com/snippets/javascript/get-url-variables/

    3. COyea if i had to guess there is something wrong with the querystring parsing. yours doesn't look bad but i would use a proven lib for this rather than debug it http://stackoverflow.com/questions/3788125/jquery-querystring

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
