废话不多说，直接给大家上干货了，写的不好欢迎提出意见。
具体代码如下所示：
function hiddenPass(event)
{
var password0 = document.getElementById("password0");
var password1 = document.getElementById("password1");
if (event.keyCode == 13)
{
}
var keycode;
if (window.event)
{ // IE
keycode = event.keyCode
} else if (event.which)
{ // Netscape/Firefox/Opera
keycode = event.which
}
var keychar = String.fromCharCode(keycode);
password1.value = password1.value + keychar;
password1.value = password1.value.substring(0,
password0.length);}function clearPass()
{
$("#password0").val("");
$("#password1").val("");
}
<li class="ba">
<label>密 码：</label>
<input type="text" id="password0"
onfocus="javascript:clearPass();"
onkeyup="this.value=this.value.replace(/./g,'*')"
onkeypress="javascript:hiddenPass(event);"/>
<input type="hidden" id="password1" name="password1"/>
</li>
