How to extract the id from URL

[ursnani]

Hi All,

I am using a Business Rule to Extract the URL parameters and I was able to get the output, but now problem is i have to extract the id from the URL.

I have used "gs.action.getGlideURI().getMap().get('sysparm_query')" to get the parameters of sysparm_query.

in that Query i have like u_field1=12345678909876543212345678^u_field2=nul.

now my requieremnt is to extract the id of Field1.

Can someone please help with this.

Thanks.

Just that little snippet of code didn't help much of where it is in the script. However, I forgot to put a return in the map method and reassing q in my previous post.
But if you're only concerned with 'u_field1' then you can modify the filter to:

var q = gs.action.getGlideURI().getMap().get('sysparm_query') + "";
	q = q.split("^")
	q = q.filter(function(item){
	  return item.indexOf('u_field1') > -1;;
	}).map(function(item){
	        var arr = item.split("=");
	        var obj = {}
                obj[arr[0]] = value: arr[1]
                gs.log(obj.u_field1, "ACTION")
                return obj;
		
	})[0]

gs.log(q.u_field1);

Here is a breakdown:

Another way of doing this and making it a reusable script with access to any parameters retrieved is as the following:

function parseSysparmQuery(parameters){
	var params = parameters + "";
	return params.split("^").reduce(function(acc,curr){
		var arr = curr.split("=");
		acc[arr[0]] = arr[1];
		return acc;
	},{})
}

Use it as follows:

var sysparmQuery = gs.action.getGlideURI().getMap().get('sysparm_query');
var getParam = parseSysparmQuery(sysparmQuery);

gs.info("u_field1: " + getParam.u_field1);
gs.info("u_field2: " + getParam.u_field2);

It could be included in a Script Include allowing it to be used in many business rules.
