将“回车（ENTER）”转成“切换（TAB）”的JS和jQuery写法

普通js

view plaincopy to clipboardprint?<mce:script type="text/javascript"><!-- 
document.body.onkeydown = function() 
{ 
if(event.keyCode == 13) 
{  
   event.keyCode = '9' 
} 
} 
// --></mce:script> 
<mce:script type="text/javascript"><!--
document.body.onkeydown = function()
{
if(event.keyCode == 13)
{
   event.keyCode = '9'
}
}
// --></mce:script>



jQuery

view plaincopy to clipboardprint?$(document).ready(function(){ 
$(document).keydown(function(){if(event.keyCode==13){event.keyCode='9';}}) 
});
