Do you have the field for numbers only?

My special JS function has been created to restrict the typing by regExp pattern:

JavaScript:


var isIE4up = (document.all) ? 1 : 0;
var isIE5 = (isIE4up && navigator.appVersion.indexOf("MSIE 5") != -1) ? 1 : 0;
var isIE6 = (isIE4up && navigator.appVersion.indexOf("MSIE 6") != -1) ? 1 : 0;

function keyFilter(e, strPattern) {
// (c) Mauzon 
  var chr = (isIE4up || isIE6 || isIE6)?e.keyCode:e.which;
  var ch = String.fromCharCode(chr);
    if (chr != 13 && chr !=  8 ) {
    var re = new RegExp(strPattern);
    if (ch.search(re) == -1) {
      if(isIE4up || isIE6 || isIE6){
       e.returnValue = false;
      }else{
       e.preventDefault();
      }
    }
  }
}

(x)HTML:


<input type="text" onkeypress="keyFilterA(event,'[0-9]')" /> lets visitor to add Integers only;
<input type="text" onkeypress="keyFilterA(event,'[0-9\.\,]')" /> numbers with decimal delimiter;
<input type="text" onkeypress="keyFilterA(event,'[a-zA-Z]')" /> letters;
