将删除和箭头键添加到正则表达式中

我正在执行日期验证，现在我正在执行该用户只能输入numbers ,/and backspace所以现在我想在正则表达式中添加 2 个键。我想添加delete and arrow keys那么我应该在正则表达式中做什么改变。这是我的代码

<input type="text" id="date" name="date" onkeypress="check(event,this);"  />

这是我的 JavaScript 代码

<script type="text/javascript">

function check(evt, id)
{

 var value = id.value;

 var theEvent = evt || window.event;
 var key = theEvent.keyCode || theEvent.which;
 key = String.fromCharCode( key );

 var regex = /[0-9|\b|/]/;

 if( !regex.test(key)) 
 {
  theEvent.returnValue = false;

  if(theEvent.preventDefault) 
   theEvent.preventDefault();
 }   
}



</script>

感谢等待您的帮助。

如果按下箭头、删除和退格键，您可以跳过输入验证

function check(evt, id)
{

 var value = id.value;

 var theEvent = evt || window.event;
 var key = theEvent.keyCode || theEvent.which;

 // Don't validate the input if below arrow, delete and backspace keys were pressed 
 if(key == 37 || key == 38 || key == 39 || key == 40 || key == 8 || key == 46) { // Left / Up / Right / Down Arrow, Backspace, Delete keys
     return;
 }

 key = String.fromCharCode( key );
 var regex = /[0-9|/]/;

 if( !regex.test(key)) 
 {
  theEvent.returnValue = false;

  if(theEvent.preventDefault) 
   theEvent.preventDefault();
 }   
}
