How to use the service portal "data" object in a HTML <script> tag

[Micael Marinho1]

Hi guys

I am implementing the google maps API on the portal, however to call it, it is necessary to place the code inside a <script> tag in HTML instead of using the common client script. The problem is that I need to pull information from tables in the servicenow to put on the map, so ideally I would be able to access the data object, from the <script> tag. I tried to use UI script with GlideAjax and the client's GlideRecord, but this type of call just doesn't work from the service portal.

Can someone help me?

I thank you for your attention, have a good day !!!

If you are coding inside a widget this will be a useful reference for you.

https://docs.servicenow.com/bundle/helsinki-servicenow-platform/page/build/service-portal/concept/c_...

It shows you examples of how the data object gets passed from Server to Client, which you should then be able to access inside your <script> tag.

when I pass the "data" object inside the <script> tag the browser console displays the following error:

"data is not defined at eval"

when I pass the "c" object inside the <script> tag the browser console displays the following error:

"c is not defined at eval"
