Unable to get the parameter value from URL

[Rakesh50]

We are trying to get the value from URL by using onload catalog client script but we couldn't.

URL : https://test.service-now.com/nav_to.do?uri=%2Fu_cx_catalog_picker.do%3Fsysparm_parent_anchor%3Dhttps:%2F%2Ftest.service-now.com%2Finteraction.do%253Fsysparm_record_list%253DORDERBYDESCnumber%2526sysparm_record_rows%253D29%2526sysparm_record_row%253D8%2526sysparm_record_target%253Dinteraction%2526sys_id%253D0ae8bcc71bafc1d8c8e7db9ebd4bcb06%26sysparm_parent_number%3DIMS0000028%26sysparm_parent_sys_id%3D0ae8bcc71bafc1d8c8e7db9ebd4bcb06%26sysparm_parent_table%3Dinteraction

From above URL we need sysparm_parent_sys_id parameter value. We tried below script please check and let us know if any corrections 

function onLoad() {
//Type appropriate comment here, and begin script below
var InteractionSysID = getParameterValue('sysparm_parent_sys_id');

alert(InteractionSysID);
if(InteractionSysID !='')
g_form.setValue('interaction',InteractionSysID);
function getParameterValue(name) {
var url = top.location.href;
var value = new URLSearchParams(url).get(name);
if (value) {
return value;
}
}
}

In alert we are getting null value

Hi,

            try this

function getParameterValue(name) {
        var url = top.location.href;
        var value = new URLSearchParams(url).get(name);
        if (value) {
            return value;
        }
        if (!value) {
            var gUrl = new GlideURL();
            gUrl.setFromCurrent();
            value = gUrl.getParam("sysparm_parent_sys_id");
            return value;
        }
    }

function getParameterValue(name){
    var url = document.URL.parseQuery();
    if(url[name]){
        return decodeURI(url[name]);
    }
    else{
        return;
    }
}
