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：
rush:js;">
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("");
}
