JavaScript HTML Redirect To Another URL

There may be cases where you don’t have as free of access to the meta information or web.config to set redirects in place. You can also do this with JavaScript!

Here’s the snippet (place this in between script tags in the body or applicable section in the body that allows HTML):

<script type="text/javascript">

Hope that helps.

How To Detect The Edge Browser And Redirect To Another Page In JavaScript

There will likely be cases where you have sites that were built for IE but are not caught up to Edge yet. What do you do in the interim? One idea that I applied on a legacy site was to inform take the Edge user to a specific page. You can always do a multitude of things when dealing with how to address the user (alerts, redirects, updates to labels on pages, etc.). I just want to show an easy way to detect and redirect.

The first thing you need to know is the Edge Browser’s User Agent String:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36 Edge/12.9600

You can take advantage of the navigator.userAgent property in JavaScript and do a quick check of it. In this example I check for “Edge” and redirect if it is contained in the string.

Place the following in a script tag inside of the head section of your html:

<script type="text/javascript">
var ver = navigator.userAgent;
if (ver.indexOf('Edge') !== -1)
window.location = "";
// Not Edge, do nothing

Hope it helps.

Write a JavaScript/HTML Form Submit Post From C# APSX Code Behind

There may be a case where you are taking information from a form and need to post it to a web site somewhere else. One quick method of performing that post is to execute it from the code behind using C# (via context.response) and JavaScript. This is a scaled down example of a case where I was submitting a POST from the code behind of a web part control:

A couple things to note:

  • You can add as many fields as you wish to post, I am only using two
  • You can use string.Format to get C# variables to put directly in the POST
protected string value1;
protected string value2;

value1 = "something";
value2 = "something else";

Context.Response.Write("&lt;form name='Form1' id='Form1' method='post' action=''&gt;");
Context.Response.Write("&lt;input type='hidden' name='__VIEWSTATE' id='__VIEWSTATE' value='' /&gt;");
Context.Response.Write(string.Format("&lt;input type='hidden' name='txtValue1' id='txtValue1' runat='server' value='{0}' /&gt;", value1));
Context.Response.Write(string.Format("&lt;input type='hidden' name='txtValue2' id='txtValue2' runat='server' value='{0}' /&gt;", value2));

Ideally you would use this in a case where you are posting content and the page you are posting to will process and serve something after the form that receives your post processes what you sent. Please do not use this snippet and blame me for a blank page 🙂
