    javascript: disabeling form fields


    Hi,

    First, excuse me for my bad English, I'm Dutch.... :-)

    I know there's a lot of information about disabeling form fields, but
    cannot find the script I need:

    I'm looking for a script where, if you fill in the first of two fields
    the second field is getting disabled and vice versa. So you can neve
    have TWO fields filled in.

    I know that this can be done with JavaScript, but I don't know ho
    exactly.

    Could anybody help me with this please?

    Thanks in regard,

    Daa

          Note that disabled fields will NOT submit.
          I found that out the hard way. :)

          A little rudeness and disrespect can elevate a meaningless
          interaction to a battle of wills and add drama to an
          otherwise dull day.

              i did'nt ask te question that I really needed to know: It's no us
              ofcourse, to disable the opposite field of the one that's filled in.
              meant the following code (that I found out myself, but thanks anywa
              ;-))

              <form>
              <input name="alpha" onclick="this.f orm.beta.value= ''">
              <input name="beta" onclick="this.f orm.alpha.value =''">
              </form>

              Supersimple, but very usefull to me, because otherwise my MySQ
              database would search for BOTH inputs, wich does'nt result in th
              records I need.

              excuse me for my bad English, again.

              Greets,

              Daa
