I am attempting to pass a parameter from one file to another via the URL after a button is clicked. These are written with Express.js (index.ejs to items.ejs).

As it stands currently I am setting the URL parameter in a defined Javascript function:

function loadItems(page, subcategory) 
 window.history.pushState(null, null, "?subcat=" + subcategory) //param set
 $('#mainContent').load(page);

where subcategory is the changing variable.

From there I am trying to read this parameter during an ASP.NET function written in embedded code blocks.

<% if(items[i].subcategory === Request.QueryString["subcat"].Value) { %> //get param
 <% if (items[i].status === "Supported") { %>
 <tr class="success">
 <td><a href="/items/edit/<%= items[i]._id%>" data-toggle="modal" data-target="#editModal">Edit</a></td>
 <td id="item name"><%= items[i].name%></td>
 <td id="subcat name"><%= items[i].subcategory%></td>
 <td id="item status"><%= items[i].status%></td>
 <td id="item desc"><%= items[i].description%></td>
 </tr>

However I am met with an error which states Request is not defined and a callback to the above if statement. It is my understanding that on the ASP.NET side of things, Request.QueryString is a part of System.Web.HttpContext.Current.

How would I go about including this into my code blocks so that I am able to pull the parameter from the URL? Or, if this is not the way to be looking at this problem, how should I go about it?

My advice would be to use code behind. Embedded code blocks are an old-school throwback from the asp days. But if you must, then you should be able to do something like this:

<%@ Page Language="VB" %>
<script run=server>
 Protected Function GetSubcat() As String
 Return Request.QueryString["subcat"].Value
 End Function
</script>

<form id="form1" runat="server">
 Subcat value is <% =GetSubcat()%>.
</form>
