 使用event对象的keyCode属性判断输入的键值 eg：if(event.keyCode==13)alert(“enter!”);

 如果要使用组合键，

 则可以利用event.ctrlKey，event.shiftKey，event .altKey判断是否按下了ctrl键、shift键以alt键

 

 例如：用回车模拟Tab:  
  <input   type="text"   name="textfield"   onkeydown="if(event.keyCode==13)event.keyCode='9'">  
  <input   type="text"   name="textfield2">
