BOLD/ ITALIC font in adobe form dynamically

  Hi Team,

I want to make the font as a BOLD in ADOBE form dynamically.

I was able to make it as BOLD but not able to make italic.

xfa.resolveNode("data.MainPage.Receipts_tax_free_2RC_1PC.Receipts_tax_free_2RC_1PC.DATA["+i+"].EXP_TYPE_NAME").font.weight = "bold";

How we can make the same as italic.

and can we make the same  BOLD + ITALIC.

Thanks

NIshant
