Need to remove 'nav_to.do?' from BR constructed URL?

[Julie Peters]

I want to copy variables from a custom table (like new_call) to the catalog item chosen.  I am using logic from Brad Tilton to move over the custom table sys_id in URL constructed from the Business Rule. 

https://community.servicenow.com/community?id=community_blog&sys_id=596dea29dbd0dbc01dcaf3231f96190b

I added a sysparm value to the url"+" sysparm_newcall_sysid=" + current.sys_id;

The BR constructs the URL fine and I see it with a log statement. Unfortunately, the instance adds the default 'nav_to.do?' to the URL which causes the on load client script to get a null value for my parameter.  If I manually cut and paste the URL from the log (without the nav_to.do?) the client script gets the value successfully. 

Is there a way to remove part of the default URL path, specifically the nav_to.do? 

The onload client script need to work for a Service Portal catalog item, so no document or window commands please.  Thank you!

Could you describe a little more about what you're doing here and include the code from the business rule? What does the final url look like? 

[Julie Peters]

Hello Brad, My BR is similar to others such as the New Call changed to Request.  It includes:

var sysid=current.sys_id;

var url="com.glideapp.servicecatalog_cat_item_view.do?sysparm_id=" + reqitem+"&sysparm_newcallid=" +GlideStringUtil.urlEncode(sysid);

gs.log(url);

action.setRedirectURL(url);

So my log url looks great.  And if I manually paste it into the URL (after the instance) my onload client script returns the newcall sysid.

function onLoad() {

       //Use the 'getParameterValue' function below to get the parameter values from the URL  

       var mycall = getParameterValue('sysparm_newcallid');

       if (mycall) {

               g_form.setValue('call_record', mycall);

       }

}

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]);

       }

}

So the problem seems to be that the new call redirect to the catalog includes the "nav_to.do?uri=" after the instance instead of just going to /com.glide  etc.  Isn't there an easy way to redirect without that nav extension?

Thanks!!

You can probably do that with an absolute url like:

var url = gs.getProperty('instance_name') + '.service-now.com/com.glideapp.servicecatalog_cat_item_view.do?sysparm_id=' + reqitem + '&sysparm_newcallid=' +GlideStringUtil.urlEncode(sysid);

The thing you lose with removing nav_to.do?uri= is the leftnav and instance header, though. I think I've used this in the past with the nav_to.do?uri= in the url successfully but I'd need to go test that.

[Julie Peters]

Good idea but no, even the hard coded adds the leftnav back.  If this were an application menu I could put window=_blank.  Is there a way to go straight to the catalog or SP view of this catalog item without the left nave included?
