1、只有下劃線的文本框：
<input style="border:0;border-bottom:1 solid black;background:;">

2、軟件序列號式的輸入框：
<script for="T" event="onkeyup">
if(value.length==3)document.all[event.srcElement.sourceIndex+1].select();
</script>
<input name="T" size="5" maxlength="3">—<input name="T" size="5" maxlength="3">—<input name="T" size="5" maxlength="3">—<input name="T" size="5" maxlength="3">—<input name="T" size="5" maxlength="3">—<input name="T7" size="5" maxlength="3">

3、軟件序列號式的輸入框(完整版)：
<script for="T" event="onkeyup">if(value.length==maxLength)document.all[event.srcElement.sourceIndex+1].focus();</script>
<script for="T" event="onfocus">select();</script>
<script for="Submit" event="onclick">
var sn=new Array();
for(i=0;i<T.length;i++)
sn=T.value;
alert(sn.join("—"));
</script>
<input name="T" size="5" maxlength="3">—<input name="T" size="5" maxlength="3">—<input name="T" size="5" maxlength="3">—<input name="T" size="5" maxlength="3">—<input name="T" size="5" maxlength="3">—<input name="T" size="5" maxlength="3">
<input type="submit" name="Submit">

4、輸入框景背景透明：
<input style="background:transparent;border:1px solid #ffffff">

5、鼠標劃過輸入框，輸入框背景色變色：
<INPUT value="Type here" NAME="user_pass" TYPE="text" SIZE="29" οnmοuseοver="this.style.borderColor='black';this.style.backgroundColor='plum'"?
style="width: 106; height: 21"?
οnmοuseοut="this.style.borderColor='black';this.style.backgroundColor='#ffffff'" style="border-width:1px;border-color=black">

6、輸入字時輸入框邊框閃爍(邊框為小方型)：
<Script Language="JavaScript">
function borderColor(){
if(self['oText'].style.borderColor=='red'){
self['oText'].style.borderColor = 'yellow';
}else{
self['oText'].style.borderColor = 'red';
}
oTime = setTimeout('borderColor()',400);
}
</Script>
<input type="text" id="oText" style="border:5px dotted red;color:red" οnfοcus="borderColor(this);" οnblur="clearTimeout(oTime);">

7、輸入字時輸入框邊框閃爍(邊框為虛線)：
<style>
#oText{border:1px dotted #ff0000;ryo:expression(οnfοcus=function light (){with(document.all.oText){style.borderColor=(style.borderColor=="#ffee00"?"#ff0000":"#ffee00");timer=setTimeout(light,500);}},οnblur=function(){this.style.borderColor="#ff0000";clearTimeout(timer)})};
</style>
<input type="text" id="oText">

8、自動橫向廷伸的輸入框：
<input type="text" style="huerreson:expression(this.width=this.scrollWidth)" value="abcdefghijk">

9、自動向下廷伸的文本框：
