Getting the masked value of a password field?
提问by Industrial
I've got a normal password field from which I would like to "get" the masked value - yep, that ugly **********obfuscated value.
我有一个普通的密码字段，我想从中“获取”掩码值 - 是的，那个丑陋的**********混淆值。

If you mean that you want a string that contains as much *as the number of characters you inserted in a password field you could do:
如果您的意思是您想要一个包含与*您在密码字段中插入的字符数一样多的字符串，您可以执行以下操作：
var password = $("#password").val();
password = password.replace(/./g, '*');

Get a string repeat functionon the go, then use this:
随时随地获取字符串重复函数，然后使用：
repeat('*', $('#myfield').val().length);
or (depending on the implementation you go with):
或（取决于您使用的实现）：
'*'.repeat($('#myfield').val().length);
My personal suggestion:
我的个人建议：
function repeat(s, n) {
return new Array(isNaN(n) ? 1 : ++n).join(s);
}
var password = "lolcakes";
console.log(repeat('*', password.length));
// ^ Output: ********

Do a regex replace on $("#myfield").val();that replaces all characters with *?
是否使用正则表达式$("#myfield").val();替换所有字符*？
alert($("#myfield").val().replace(/./g, '*'));
