我的任务
分享帮忙来看看这样的效果可以做到么?
<script language="javascript" type="text/javascript">
<!--
function isTrue( oCars)
{
return window.confirm("确定选" + oCars.options[oCars.selectedIndex].text);
}
//-->
</script>
<select name="test" id="test" onChange="return isTrue( this);">
<option value="1">a</option>
<option value="2">b</option>
<option value="3" selected="selected">c</option>
</select>
我要的是用户每change一次都有个确认框,如果是则选中用户选的那个,否则的话就选中原先的那个,但这个return false怎么不行?
要这样的效果要怎么弄?
