How do you read URL from Catalog Client Script

[marclindsay]

I have created a UI Action that runs server side and redirects a user to a Record Producer. The UI Action adds data to the URL (UI Action Redirect : com.glideapp.servicecatalog_cat_item_view.do?sysparm_id=21378b88db9e2300c218d740cf961961&sysparm_comments=testing passing information). Within the Catalog Client Script I am trying to read the URL to get the parameter needed for defaulting some of the fields on the Record Producer screen.

Everything I have read looks like I should be able to do the following to get my data out of the URL. document.URL.parseQuery();  This command is not working. I keep getting the error 'Cannot read property 'URL' of null'.

Stuck as to how I get my information out of the URL

Hi M,

So lets say you want to read u_xyz parameter from url, lere is the sample code

var xyz= getParmVal('u_xyz');   //called from client script

//Function in the same script

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

that is what I am doing but it I am getting an error. I am not doing this from a Service Portal. Just using the native screens (ServiceNow Internal / Fullifer view).

Below is the code in my Client Script, and I keep getting an error with the document.URL.parseQuery(); statement.  Error "Cannot read property 'URL' of null"

function onLoad() {
    
   
    //Type appropriate comment here, and begin script below
    var comm = getParmVal('sysparm_comments');
    g_form.addInfoMessage("after Parm comment : " + comm);
    
    g_form.setValue("description", comm);
       
}

function getParmVal(name) {

    var url;
   
    try {
        url = document.URL.parseQuery();
        g_form.addInfoMessage("Parm 2b : " + url);
    }
    catch (err) {
        g_form.addInfoMessage(err.message);
    }
    g_form.addInfoMessage("Parms 3 : " + url);

     if(url[name]){
         return decodeURI(url[name]);
     }
     else{
         return;
     }

}

Hello,

Please try this out

function onLoad() {
var desc = getParameterValue('sysparm_comments');
if (desc) {
g_form.setValue('description', desc);
}

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

Did this. I am still getting an error with the document.URL.parseQuery() statement. 

I am doing this in a personal Instance would that be impacting this command?
