How to enable Isolate Script in Case Form?

[Syed Asad]

Hi,
I am new to the ServiceNow community and I am facing issues in accessing DOM Objects like getElementById() in Client Script. I have imported an application and I am getting this message :

New client scripts are run in strict mode, with direct DOM access disabled. Access to jQuery, prototype, and the window object is likewise disabled. To disable this on a per-script basis, configure this form and add the "Isolate script" field. To disable this feature for all new globally-scoped client-side scripts set the system property "glide.script.block.client.globals" to false.


I referred to this Article https://community.servicenow.com/community?id=community_blog&sys_id=c5c46364dbba6b007d3e02d5ca9619cb Which says I need to Uncheck Isolate Script Checkbox. But Isolate Script field is not visible in the Form Design configuration. 

Please help me understand how I can access DOM objects in Client Script in a custom application and where I will get this Isolate script in case form? Any help will be much appreciated.

Please refer to the Screenshots.

Thanks!

Hi

you shouldn't ask for a solution which is not recommended (DOM manipulation) but explain what your business requirement is.

Then we can find a suitable solution which won't break at the next ServiceNow upgrade.

Therefore please explain what youwant to reach and provide all necessary details.

Kind regards
Maik
