急！TEXT只允许输入金额的问题？

Question

数字是48到57，那么小数点的KEYCODE是多少？

Answer 1

<input type=text name=txt onkeypress="test(this)"><script>
function test(o) {
  var re = /\.\d\d/;
  if(re.test(o.value))
    o.value = o.value.replace(/(.+)\d/,"$1");
}
</script>js的写法，自己改成vbs吧

Answer 2

唠叨下，请问“var re = /\.\d\d/;”这句的格式是怎样解释？
