document.URL.parseQuery() suggestion to replace

[Jim J1]

We are getting tagged in Health Check for var url = document.URL.parseQuery(); as DOM manipulation issue. Looking for suggestions to replace 'var url = document.URL.parseQuery();' in client script

Re: How to get entire URL in Client Script OR sysparm

Here is a deep dive:

IMO, using DOM to snag the url will always be supported but I understand the need to be in full compliance.

I have created a catalog client script to grab the URL parameters on a catalog item coming from NEW CALL.  I have written the client script the same way the OOB client script "Propose a new Standard Change Template" is written but I cannot get the parameters out of the URL.

Here's my client script:

I've also tried it without trying to get two parameters (just the Requested For)

Any ideas why this doesn't work but the Standard Change Template client script does?  Only difference I can find is the Change Template is a Record Producer, not a Catalog Item.

Here's my URL:

	}
		
	if (details){
		if (g_form.getControl('description'))
		g_form.setValue('description', details);
	}
}


function getParmVal2(name){
	var url2 = document.URL.parseQuery();
        alert("URLName=" + url[name]);
	if(url2[name]){
		//We never get here
		return decodeURI(url2[name]);
	}
	else{
		return;
	}
