    hi

    when someone fills in a username field i dont want them to have spaces or special characters

    i found a function


    function f(o){
    o.value=o.value.toUpperCase().replace(/([^0-9A-Z])/g,"");
    }


    however this changes the letters to capitals - anyone know how i can allow upper and lower caps, no spaces or special characters?

    isnt it something like this?

    function f(o){
    o.value=o.value.toUpperCase().replace(/([^0-9a-zA-Z])/g,"");
    }


    incidently I would suggest you have a look at this

    skidpatches is right - get rid of the toUpperCase()
