武林网(www.vevb.com)文章简介：input输入框的各种样式。
输入框景背景透明：
<input style=background:transparent;border:1px solid #ffffff>
鼠标划过输入框，输入框背景色变色：
<INPUT value=Type here NAME=user_pass TYPE=text SIZE=29 onmouseover=this.style.borderColor='black';this.style.backgroundColor='plum'
style=width: 106; height: 21
onmouseout=this.style.borderColor='black';this.style.backgroundColor='#ffffff' style=border-width:1px;border-color=black>
输入字时输入框边框闪烁(边框为小方型)：
<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 onfocus=borderColor(this); onblur=clearTimeout(oTime);>
输入字时输入框边框闪烁(边框为虚线)：
<style>
#oText{border:1px dotted #ff0000;ryo:expression(onfocus=function light (){with(document.all.oText){style.borderColor=(style.borderColor==#ffee00?#ff0000:#ffee00);timer=setTimeout(light,500);}},onblur=function(){this.style.borderColor=#ff0000;clearTimeout(timer)})};
</style>
<input type=text id=oText>
自动横向廷伸的输入框：
<input type=text style=huerreson:expression(this.width=this.scrollWidth) value=abcdefghijk>
自动向下廷伸的文本框：
<textarea name=content rows=6 cols=80 onpropertychange=if(this.scrollHeight>80) this.style.posHeight=this.scrollHeight+5>输入几个回车试试</textarea>
只有下划线的文本框：
<input style=border:0;border-bottom:1 solid black;background:;>
软件序列号式的输入框：
<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>
