How to pass this variable value here? Below code is not working. And all other discussions on Stackoverflow are unclear.

<script type="text/javascript">
        function check()
        {
            var dist = document.getElementById('value');
            if (dist!=""){
                window.location.href="district.php?dist="+dist;
            }
            else
               alert('Oops.!!');
        }
</script>

And my HTML code is:

<select id="value" name="dist" onchange="return check()">
location-href href javascript

I use a very different approach to this. I set browser cookies in the client that expire a second after I set window.location.href.

This is way more secure than embedding your parameters in the URL.

The server receives the parameters as cookies, and the browser deletes the cookies right after they are sent.

const expires = new Date(Date.now() + 1000).toUTCString()
document.cookie = `oauth-username=user123; expires=${expires}`
window.location.href = `https:foo.com/oauth/google/link`
