Replace all words by javascript except one particular word

I want to replace every word including "before" except one particular word including "before" (case-insensitive)

Example: "before" = "after“; except "beforethree"

beforeone beforetwo beforethree beforefour

Result should be:

afterone aftertwo beforethree afterfour

My code is:

  <script>
function Replace() {
    var str = document.getElementById("id").innerHTML; 
var res = str.replace(/before/gi, "after");
    document.getElementById("id").innerHTML = res;
}
</script>

Thank you guys very much in advance!

Modify your replace to be this instead

<script>
function Replace() {
    var str = document.getElementById("id").innerHTML; 
    var res = str.replace(/(?!beforethree)before/gi, "after");
    document.getElementById("id").innerHTML = res;
}
</script>

You could use a negative lookahead regex instead:

/before(?!three)/gi

one option would be to

  1. replace beforethree with something safe like %%three
  2. replace before with after
  3. replace %% with before

I'm sure there are more elegant solutions out there
