SetFocus does not work on iPad

问题

We found that this code works on a PC with: IE, Safari and FireFox. However on an iPad or iPhone with Safari it does not auto focus on a textbox. We cannot touch the screen and click the textbox, we need the auto focus. Any tips here?

thanks!

<script language='JavaScript'>
<!--
function SetFocus()
{
    document.form1['txtCode'].focus();
}
window.onload = SetFocus;
// -->
</script>

Unfortunately, it appears Mobile Safari does not support this behaviour, by design.

<body onload="document.getElementById('txtCode').focus();">
    <form>
        <input type="text" value="Text Here" name="txtCode" id="txtCode" />
    </form>
</body>
