<input type="text" class="txt" maxlength="5" placeholder="1"/> <br/> <input type="text" class="txt" maxlength="5" placeholder="2"/> <br/> <input type="text" class="txt" maxlength="5" placeholder="3"/>
<script>
var txt = document.getElementsByClassName("txt"); for(var i=0;i<txt.length;i++){ txt[i].onkeyup = function(){ if(this.value.length == 5){ this.blur(); txt[i+1].focus(); }; }; }
</script>

需求是這樣的：在輸入框輸入內容之后，自動將焦點定位到下一個input上
表單焦點自動切換
