jQuery not getting the password field value
提问by user2356932
I have searched a lot in stackoverflow and other sites and got many solutions but nothing solved mine.That is why I am posting this.I have a password field in my web page, which was created dynamically on a link click.And I want to get the value typed in that password field into a variable when it loses focus.For that i created a jQuery function like this.
我在 stackoverflow 和其他网站上搜索了很多，得到了很多解决方案，但没有解决我的问题。这就是我发布这个的原因。我的网页中有一个密码字段，它是在链接点击时动态创建的。我想当它失去焦点时，将在该密码字段中键入的值放入一个变量中。为此，我创建了一个像这样的 jQuery 函数。
$('#parentdiv').on('focusout', '#passwordfield', function() {
var pass1 = $('#passwordfield').val();
alert(pass1);
alert("Hello");
});
Here the first alert command will displayed with nothing, but the second alert come with "Hello". Which means, when the password field loses its focus this function executes without any problem, but the problem is, it is not getting the password field value.
这里第一个警报命令将不显示任何内容，但第二个警报带有“Hello”。这意味着，当密码字段失去焦点时，该函数执行没有任何问题，但问题是，它没有获取密码字段值。
Please help me to solve this problem.

我的解决方案基于上述想法：

});
