vim - How to quickly select a word and surround it with a special character while developing a program?

Question

For example, there is a word {code...}. I have selected the word in v mode. Is there any shortcut key to add quotation marks on both sides of the word to make it {code...}?

The configuration file adds functions and key mappings as follows:

function! s:surround()
    let word = expand("")
    let wrap= input("wrap with: ")
    let command = "s/".word."/".wrap.word.wrap."/"
    execute command
endfunction
nmap cx :call surround()

In this way, place the cursor on the word in normal mode, and then use the shortcut key cx. It will prompt the characters to be filled on both sides. Just enter the characters and press Enter.
