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">
软件序列号式的输入框(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">
.c
{
border:solid 1px #ccc;
}
.u
{
border:solid 1px red;
}
<input type="text" onclick="javascript:this.className='c'" onblue="javascript:this.className='u'"/>
<script type="text/javascript" language="javascript">
function changeborder()
{
document.getElementById('<%=txtAccount.ClientID%>').style.borderColor="Red";
}
</script>
然后在textbox中加入onfocus
<asp:TextBox ID="txtAccount" runat="server" Width="132px" onfocus="changeborder();"></asp:TextBox>
可以在页面中加入javascript如下:
<script type="text/javascript" language="javascript">
function changeborder()
{
document.getElementById('txtAccount').style.borderColor="Red";
}
</script>
然后在textbox中加入onfocus,如下:
<asp:TextBox ID="txtAccount" runat="server" Width="132px" onfocus="changeborder();"></asp:TextBox>
这里是把border的颜色改成了red,你自己也可以随便修改。
如果是失去焦点的话,可以使用onblur事件
onblur="changeborderback();"
javascript函数添加
function changeborderback()
{
document.getElementById('txtAccount').style.borderColor="White"
}
<asp:TextBox ID="txtAccount" runat="server" Width="132px" onfocus="changeborderback();"></asp:TextBox>
