Using Request.QueryString in ASP.NET Embedded Code Block
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>

Would I be able to implement this if all of the pages that I am using are.ejsfiles, or is that going to be problematic?

The code won't work unless they are ASP.NET .aspx pages. How would an .ejs file know anything about .NET?

That's what I thought, sorry I'm very new to web app development so I'll probably ask some (really) dumb questions. Is there a way to call the .aspx pages? The entire app is written in .ejs/.js so far.
