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 Syed,

You can open the list view of client script and set true from there.

Hope it helps.

Hi Ujjawal,

Thanks, for the reply. I opened the list view of the Client script but there also can't see the Isolate Script option. 

Actually, I am using DOM objects like getElementById in one of my client scripts but somehow I am unable to fetch elements value from the DOM. I searched on google and got an Article that explains that I need to uncheck the Isolate Script field. But I can't see the Isolate Script option anywhere in my Instance.

Thanks!

You can personalize the list and then you can add isolate field
