You got an extra ")" in your code. It should be this way:

oListItem.set_item('Pieces Unaccompanied Hold Baggage(Rush)', "value");

But, in oListItem.set_item() method, the first parameter shoult be the INTERNAL NAME of the field. You will find the internal name in the URL when you open the field (column) settings. So it should be

oListItem.set_item('InternalName', value)
  • i removed it but the main error that if field name is more than 2 words it does not work Nov 6, 2018 at 13:23
  • You should use the internal name in the set_item function. I have mentioned it in the answer. Nov 6, 2018 at 13:25
  • What you are using I suppose is the Display name (name which appears on forms and list views). Nov 6, 2018 at 13:26
  • thanks it works but the internal name it only appeared in the URL of the page not on the form Nov 6, 2018 at 13:34
  • Yes. A SharePoint field has 3 names - Internal Name (unique name over the site which appears in URL), Display Name (Unique Name within List which appears on forms and list views), static name (somewhat similar to internal).
