Firefox 23 - Key Event dosen't work

more options

After I installed firefox 23 javascript function used to make a mask entry fields stopped working. Until version 22 function worked.

MaskInput = function(f, m){
 function mask(e){
  var patterns = {"1": /[A-Z]/i, "2": /[0-9]/, "4": /[À-ÿ]/i, "8": /./, "16": /^[-]?(\d{0,99})?$/ },

  function accept(c, rule){
   for(var i = 1, r = rules[rule] || 0; i <= r; i<<=1)
    if(r & i && patterns[i].test(c))
     break;
    return i <= r || c == rule;
  }
  var k, mC, r, c = String.fromCharCode(k = e.key), l = f.value.length;
  (!k || k == 8 ? 1 : (r = /^(.)\^(.*)$/.exec(m)) && (r[0] = r[2].indexOf(c) + 1) + 1 ?
   r[1] == "O" ? r[0] : r[1] == "E" ? !r[0] : accept(c, r[1]) || r[0]
   : (l = (f.value += m.substr(l, (r = /[A|9|C|\*]/i.exec(m.substr(l))) ?
   r.index : l)).length) < m.length && accept(c, m.charAt(l))) || e.preventDefault();
 }
 for(var i in !/^(.)\^(.*)$/.test(m) && (f.maxLength = m.length), {keypress: 0, keyup: 1})
  addEventMask(f, i, mask);
};

addEventMask = function(o, e, f, s){
    var r = o[r = "_" + (e = "on" + e)] = o[r] || (o[e] ? [[o[e], o]] : []), a, c, d;
    r[r.length] = [f, s || o], o[e] = function(e){
        try{

            e.target || (e.target = e.srcElement || null);
            e.key = (e.which + 1 || e.keyCode + 1) - 1 || 0;
        }catch(f){}

        return e = null, !!d;
    }

            return delete e[i];

Bewurke troch cor-el op

Keazen oplossing

After I debug the code I found the solution, in Firefox 22 e.key works but in Firefox 23 this attribute does not work, then switched e.key by e.charCode

Try posting at the Web Development / Standards Evangelism forum at MozillaZine. The helpers over there are more knowledgeable about web page development issues with Firefox.

Thanks for the reply, but I would like to know if there are any bug in the FF23 Key Event, because the behavior change in the last version ?

The same javascript is used since Firefox 3, only now started to not work.

I might be necessary to define functions before referencing to them, so you can try to define addEventMask() before function mask(e) which calls this function.

You can check the Browser/Error Console (Firefox/Tools > Web Developer;Ctrl+Shift+J) for errors.
