Type this:

Answer 1

My solution:

inoremap   InsertMapForEnter()
function! InsertMapForEnter()
    if pumvisible()
        return "\"
    elseif strcharpart(getline('.'),getpos('.')[2]-1,1) == '}'
        return "\\O"
    elseif strcharpart(getline('.'),getpos('.')[2]-1,2) == '\O"
    else
        return "\"
    endif
endfunction

Explaination:

The code above first check if you are using Enter to do confirm a code completion, if not it will indent the {|} when you type Enter. Also, it provides html tags auto indent.

Examples:

if( whatever ){|}

press Enter and you will get

if( whatever )
{
  |  
}

This also works for html file. See the following example
