推荐答案
您可以像这样做纯JavaScript:
You can do pure javascript like this:
<script type="text/javascript">
function ValidatePassKey(tb) {
if (tb.TextLength >= 4)
document.getElementById(tb.id + 1).focus();
}
}
</script>
<input id="1" type="text" onchange="ValidatePassKey(this)" maxlength="4">
<input id="2" type="text" onchange="ValidatePassKey(this)" maxlength="4">
<input id="3" type="text" onchange="ValidatePassKey(this)" maxlength="4">
<input id="4" type="text" maxlength="4">
