Javascript help in Acrobat form fields

Sure! I tried code I found in another discussion on here.

var spans = event.richValue;
if (spans !== undefined && event.willCommit) {
for ( var i = 0; i < spans.length; i++ ) {
spans[i].textSize = 17; // font size
spans[i].linespacing = 22 // linespacing

// restore line breaks
if (spans[i].endParagraph) spans[i].text += "\r";

// reset styles to default
spans[i].fontStyle = "normal";
spans[i].fontWeight = 400;
spans[i].strikethrough = false;
spans[i].underline = false;
spans[i].textColor = color.white;
spans[i].alignment = "left";
spans[i].fontFamily = ["Poppins-Medium"];
}

event.richValue = spans;
}

It works when you tab out of the field.
