JS实现软键盘的效果源代码（经典）

见过很多网站在输入密码的时候使用的软键盘吗？你想在自己的网站上也有这样的功能吗？下面就是源代码！

//定义当前是否大写的状态
//<input name="UserPassword" type="Password" size="15" maxlength="15" onMouseOut="this.style.background=''" onMouseOver="this.style.background='#F9F9F9'" onFocus="this.select();" readOnly onKeyDown="Calc.password.value=this.value" onChange="Calc.password.value=this.value" onclick= "password1=this;showkeyboard();this.readOnly=1;Calc.password.value=''">
