Get 'id' value of service portal URL in catalog client script

[Kalesh A1]

For example if I have a URL that looks like below

https://xxx.service-now.com/sp?id=I_NEED_THIS_VALUE&sys_id=XXXXXXXXXXXXXXXXX&sysparm_category=XXXXXX...

From this url is it possible to get value of 'id' in catalog client script

Hi @Kalesh A1,

There may be multiple ways:

var url = document.URL.parseQuery();
    if (url['id']){
 var id = decodeURI(url['id']);
}

var gUrl = new GlideURL();
gUrl.setFromCurrent();
var id = decodeURI(gUrl.getParam('id'));

1. For first code snippet it gave me a console error:

2. Second code snippet gave me a different JavaScript console error

Hi @Kalesh A1,

Sorry, I was thinking backend 🙂

Try this:

function onLoad() {

alert(getParameterValue('id'))
}   
function getParameterValue(name) {  
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");  
var regexS = "[\\?&]" + name + "=([^&#]*)";  
var regex = new RegExp(regexS);  
var results = regex.exec(top.location);  
if (results == null) {  
	return "";  
} else {  
	return unescape(results[1]);  
}  
}
