以下方法是其他版本 大家可以试下
<script type="text/javascript">
document.onkeydown = function(e){
if(!e) e = window.event;//火狐中是 window.event
if((e.keyCode || e.which) == 13){
document.getElementByIdx_x_x("auto").click();
}
}
</script>
document.onkeydown = function(e){
if(!e) e = window.event;//火狐中是 window.event
if((e.keyCode || e.which) == 13){
document.getElementByIdx_x_x("auto").click();
}
}
</script>
