Get values from a textarea on UI Page

[JoanaFernandes]

Hello everyone!

I have an issue with my textarea on the UI page. I need to create a GlideModal with some fields for the user to update them if he needs it, but on the description field I'm required to have a textarea field. The problem is I can't get that value and I need to confirm if description the field is empty or not before updating, if it's empty I don't want to update the form. The other fields are all working except the textarea one. The processing script is attached here as well with the hmtl script and the GlideModal. Can anyone help me with this please?

Thank you!

Hi @JoanaFernandes 

Can you share code of how DescriptionValue is defined and mapped with the html field?

Follow the same logic you followed for the other fields,I can see resolutionInfo is properly mapped.

Refer below link on how to get value from your HTML field value into Processing Script.

Hi @Voona Rohila !
The html code is showed on one of the screenshots I sent. I don't have DescriptionValue defined inside the html, only on the processing script and the client script. I'll look into the link to sent to see if it'll fix!

Best wishes,

@Voona RohilaI fixed the issue, the textarea has a white space it doesn't start with an empty value, so I had to use the trim() to get the function to work! Thank you for your help!
