onkeydown事件不触发
<input type=text class="InputNumber" DataType="+" iQty="" minQty="0" onkeydown="NewLine()" onchange="CheckInvQty(this,0)" value="" onfocus="InputData()"/>
我在table中有这样一个input，有onkeydown onchange onfocus三个事件，唯独onkeydown不被触发，我这样写有什么问题么

测试了没问题

试试 onkeydown="return NewLine(event);"

JScript code

function NewLine(e){
var keynum
var keychar
var numcheck

if(window.event) // IE
  {
  keynum = e.keyCode
  }
else if(e.which) // Netscape/Firefox/Opera
  {
  keynum = e.which
  }

keychar = String.fromCharCode(keynum)
numcheck = /\d/
return !numcheck.test(keychar)
}
