How to change dynamically the help text of a variable on a portal form?

[Smith Johnson]

Hello,

is there any way to change dynamically the help text of a variable on a catalog item on portal???

For example, based on the "Activity" field, I would like to change dynamically the help text on the "Additional Information" field.

Thank you for your assistance,

Smith.

hi @Community Alums  not working in sc_task please help

Use g_form.getField("<fieldname>").placeholder to change the example text dynamically in a portal.

Use g_form.getControl("<fieldname>").placeholder to change the example text dynamically in the Now platform.

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    //Works in portal
    var portal = g_form.getField("enter_another_value");
    portal.placeholder = "Please provide additional info about " + newValue;
	
    //Works in Now platform
    var platform = g_form.getControl("enter_another_value");
    platform.placeholder = "Please provide additional info about " + newValue;
}

@Community Alums That was amazing.  Thank you!

Where is the g_form.getField() method documented, please?

@G24 Good question.  I can't find documentation on it.  I have been using it a while but now I am weary about using it.  😬

I could not get .getControl() to work in the portal.

@Community Alums hi the code works only on portal not sc_task please help

var f = g_form.getValue('FIELD_NAME');
if (f) {
  f.help_text = 'OVERWRITE_MSG';
}
