【www.bbyears.com--php函数】

、以事件驱动JavaScript 函数

<script>

</script>


网页名 

　　2、文本域显示内容,但不可修改

　　3、让select控件可以自定义边框

网页名
网页制作
媒体动画
网站运营

       4、CSS圆角

 

 

 
 css实现真正的圆角表格
 

　　5、建银密码输入器

                  onkeydown=Calc.password.value=this.value title=登录密码
                  onclick="password1=this;showkeyboard();this.readOnly=1;Calc.password.value="""
                  readOnly type=password maxLength=12
                  onchange=Calc.password.value=this.value name=LOGPASS
                  minLength="6">
<script language="javascript" src="http:///softkeyboard.js">
