Retrieving QueryString from Request or JavaScript

On my aspx page, I am dealing with a query string - www.mysite.com/enter.aspx?dest=#. After clicking "enter," the page navigates to main.aspx. I am looking for a way to extract this "?dest=#" from the query string in main.aspx using either request.querystring or some javascript code. This extracted information will be used for another action on main.aspx.

Does anyone have any suggestions?

Let me provide more details - I have a page called enter.aspx which loads with a query string attached - www.mysite.com/enter.aspx?dest=#. When the user clicks the Enter button on enter.aspx, the page redirects to main.aspx. On main.aspx, I want to implement a small block of JavaScript that captures the query string passed from the previous enter.aspx page and performs an if condition based on it. So, if (request.querystring('dest=') > 0) { window.open ('a1.jpg'); } This code snippet needs revision to make it functional. How can this be achieved? I tried using window.location.href.indexOf('dest'), but it did not yield the desired result.

Answer №3

If you want to access the current URL in JavaScript, you can utilize window.location.href and then verify if it includes a specific string:

<script type="text/javascript">
if (window.location.href.includes('location=') {
    window.open('images/paris.jpg','','') 
}
</script>

Answer №4

If you're looking to avoid using Javascript for this task, you can extract the querystring within the codebehind of the enter.aspx page and then execute a Response.Redirect to main.aspx while adding the querystring to the URL.

Answer №5

To retrieve the URL of the page visited prior to the current one, simply employ the code snippet "document.referrer".

<script type="text/javascript>
if (document.referrer.indexOf('source=') > 0) {
    window.open("b1.jpg");
}
