You can get the part after ? in URL using window.location.search and you have to manually parse it in JavaScript. Similar question with the solution you need: https://stackoverflow.com/a/901144/1608594

Please use below javascript function to fetch querystring value in javascript.

<script>
function getParameterByName(name, url) {
    if (!url) url = window.location.href;
    name = name.replace(/[\[\]]/g, "\\$&");
    var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
        results = regex.exec(url);
    if (!results) return null;
    if (!results[2]) return '';
    return decodeURIComponent(results[2].replace(/\+/g, " "));
}

// query string value
var eid = getParameterByName('eid');
</script>

You can use it as a javascript variable globally.

<script>
    var eid = "<?php echo $eid;?>";
</script>

in your template, echo the value in a javascript variable:

var id = '<?php echo $eid; ?>';

The quotes are not needed when you echo an integer.
