例如:
<html>
<body>
<form name="input" action="/html/html_form_action.asp" method="get">
I have a bike:
<input type="checkbox" name="vehicle1" value="Bike" checked="checked" />
<br />
I have a car:
<input type="checkbox" name="vehicle2" value="Car" />
<br />
I have an airplane:
<input type="checkbox" name="vehicle3" value="Airplane" />
<br />
<input type="text" name="vehicle3"/>
<br />
<input type="radio" name="dst_mode" value="0" />
<label id="dst_week_mode">Week mode</label>
<input type="radio" name="dst_mode" value="1" />
<label id="dst_date_mode">Date mode</label>
<br /><br />
<input type="submit" value="Submit" />
</form>
</body>
</html>
在ie下按tab键,就会按从上倒下,从左到右的顺序让各个控件得到焦点。但是在safari5以上的版本却不起作用。不知道怎么实现,请大家帮忙!
