Not sure on your particular use case but one non-javascript related approach that kinda gets you there would be to use custom Skuid-UI fields like so:

1. Create a UI-Only field of type text which you then put on your page layout
2. Create a UI-Only field of type formula which uses the formula:

UPPER({{YOUR_Ui_TEXT_FIELD}})

3. Create an action on that model which updates your Salesforce field that you want in capital letters whenever the Ui-Only text field is updated.

Dig? The issue with this is it’s not validation but it does enforce capitalised output.

Hi Louis, 

Good suggestion but unfortunately this wont fix what I am trying to achieve. It is using caps I intended to block the iphones predictive text. 

Any more suggestions?

Matt,

I have not tried this myself, but it looks like you can add an attribute to the input to turn off ‘autocapitalization’. See this link-> https://stackoverflow.com/questions/4722623/disable-predictive-text-on-iphone-for-a-form-field

Here is an example:

<input type="text" autocomplete="off" autocorrect="off" autocapitalize="off">

Thanks,

Bill

Thanks Bill for sharing your idea!
