Question

Im trying to write a function that will convert all charactewrs after the first word into asterisks,

Say I have MYFIRSTWORD MYSECONDWORD, id want it to convert to asterisks on Keyup, but only for the second word, rendering it as so…

MYFIRSTWORD ***

I’ve been using the following only it converts each and every letter, is this possible?

$(this).val($(this).val().replace(/[^\s]/g, "*"));

I’m not sure about doing it with a single regex, but you can do this:

$("input").keyup(function() {
    var i = this.value.indexOf(" ");
    if (i > -1) {
        this.value = this.value.substr(0, i) 
                   + this.value.substr(i).replace(/[\S]/g, "*");
    }
});
