Hi @JackieZhang ,

You can use the below logic to get the user name and then you can add your own code if you want to set it to a particular field or anything else.

 var gUrl = top.location.href; //getting the URL
//fetch the parameter from url, add the replace the param_name with your parameter name.
    var uName = new URLSearchParams(gUrl).get("param_name");

Sorry, where do I need to add it to?

@JackieZhang This is a scipt to fetch the value. This can directly be used in a client script.

I saw the url that you gave as a reply. In the reply you are sending the user name as 'name' (name=jackie). 

In the script I gave, replace "param_name" with "name".
After doing so, add one line for setValue for setting the field you want to the 'name' parameter's value. Below is an example 

g_form.setValue('your_field_backend_name', uName);
