Get URL value in client script

[Rj27]

Hi,

I am trying to load portal page from a ui page. This page is a record producer.
I am able to to that (loading portal page).
Suppose my url that coming on portal is :https://<INSTANCE>.service-now.com/portal?id=sp_home&sysparm_product_sysid=<product sys id>

I want to give a check if sysparm_product_sysid has some value then the a field on item should be auto checked as true on load.

For this i have added a onload client script in my record producer. 

My ui type is set to Mobile/Service portal on client script .

and I have enabled isolate script to true.

Tried both ways but none of them is working. When the portal is loaded, its giving error..

1. 

   var prdID = getParmVal('sysparm_product_sysid');
   if(prdID){
      alert('prd');
	   //g_form.addInfoMessage('prd'); 
   }
}

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

Error:

2.

var gUrl = new GlideURL();
gUrl.setFromCurrent();
var prdID= gUrl.getParam("sysparm_product_sysid");
alert('prdID  '+prdID);

Error message:

Hi, you can use the property top.location.href in combination with the JavaScript object URLSearchParams. This makes it very flexible and easy to use.

Here is an example script:

        var url = top.location.href;
        var params = new URLSearchParams(url);
        var parentSysId = params.get('sysparm_collectionID');
        if (parentSysId) {
            g_form.setValue('task', parentSysId);
        }
