I suggest you look up how to do regular expressions, they help outheaps.  For just a basic string (using just letters or numbers assymbols can have a different meaning) then you can use my code as anexample and put the likes of the following

code:

---

var replace1 = /text/gi;
function ...(...){
    string = string.replace(replace1,"text to replace it with");
}

---

For symbols like / \ . * $ ^ + ?  etc then you will need to prefix those characters with \

There are a heap more thing involved in regular expressions but those few things will get you started (though I suggest you try learning more).
