How to call mobile client script in the Submit button in the mobile app

[Elvin_Salim]

Is there a way to call a mobile client script in the Submit-Save button on the mobile app? 

The idea is that when a specific field on the screen gets an error message and then display a confirmation popup message when the user clicks the Submit-Save button to submit the record.

Mobile UI actions are stored on the sys_ui_ng_action table, and are accessible on the instance by navigating to System Mobile UI → UI Actions - Mobile. 

Try below script in it and see if it helps

function onSubmit() {

   g_form.addInfoMessage("Submission successful!");

   // or you could do an alert on the browser
   alert("Submission successful!")
}

Hello @Ct111 ,

All I can find is that the buttons are on global scope in the ys_ui_ng_action table which is not in the mobile app scope which I am working with. It seems that some buttons are built-in buttons in SN which are not configurable too much. 

BR,

Elvin
