How to set field value in existing record using Navigation URL?

[michelhanna]

Hi,

I need to construct a navigation URL, which will act as a callback URL to servicenow from a 3rd party system. The URL will open an existing record in one of the tables and set a value in a specific field..

I've the following URL where I open an existing record by sys_id, then passing a value to the target field, but didn't work:

https://<baseURL>.service-now.com/nav_to.do?uri=<table name>.do?sys_id=<sys_id_for_target_record>%26sysparm_query=target_field=xyz

Is that something doable?

Thanks,

Michel

Unfortunately that API only works for new records

If you want to set specific values on load for existing records you'll need to use a Client Script or Display Business Rule.

You could be tricky and put a useless parameter in the URL, then use an onLoad client script to parse the URL and set the values if required.

example URL

incident.do?sys_id=8f632fea6f560200884750be5d3ee462&parm1=test

function onLoad() {

     //Type appropriate comment here, and begin script below

       if (top.window.location.href.indexOf("parm1=test") > -1 ) {

   g_form.setValue('short_description','Redirected from URL');

   }

}

Excellent work around! I've tried it and I was able to capture the sent value which in your example = 'test'.

Thanks.

The example HTML is obtained by looking at the current browser window.

I have a slightly different example:

In my case, I open a webpage from within the main ServiceNow frame (the navbar and servicenow header are still there).  I click on a link on the webpage and it will send it back to the incident ticket where I want to do the same thing with regards to processing the URL and having a parameter.

top.window.location.href is incorrect because it's still looking at the main servicenow link, so how do I look at the current frame instead?
