How to Retrieve URL Parameters in a Catalog Client Script Without Using DOM in Employee Center Porta

[Mohan Mallapu]

Hello Community,

I am working with the Employee Center portal in ServiceNow and have opened a catalog form. I need to retrieve parameters from the URL of this catalog form using a Catalog Client Script, but I want to achieve this without relying on DOM manipulation.

For example, if the URL is:

https://<instance>.service-now.com/sp?id=sc_cat_item&sys_id=12345&param1=value1

I want to extract the param1 value (in this case, value1) programmatically in a way that is robust and does not involve accessing the DOM directly.

Could someone guide me on the best approach to achieve this? Any code examples or best practices would be highly appreciated.

Thank you for your help!

Hi @Mohan Mallapu ,

You can do something like below.

var gUrl = new GlideURL();
gUrl.setFromCurrent();
var param1= gUrl.getParam("param1");


/// Or something like below.

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_id");
            return value;
        }

Hi @Runjay Patel ,

GlideURL will not work on the employee center side and the second code using the DOM.
