<p>I was doing password matching concept and it was working fine when i entered the passwords in it and it shows "Passwords match" or "Passwords didn't match". But here is the problem or can say bug kind of thing. When your passwords match and then suddenly you remove both the passwords in the boxes it still shows "passwords match" or "passwords didn't match". I am posting an image of for better understanding.</p>

<p><a href="https://i.stack.imgur.com/Jt0EG.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Jt0EG.jpg" alt="enter image description here"></a></p>

<p>So how to hide or remove that "passwords didn't match or passwords match" comment when both the passwords are empty in the boxes. I am posting the code below on what i did</p>

<p>HTML</p>

<pre><code>&lt;p&gt;
    &lt;input type="password" name="NPassword" placeholder="New Password" id="txtNewPassword" /&gt;
&lt;/p&gt;
&lt;input type="password" name="RNPassword" placeholder="Retype New Password" id="txtConfirmPassword" onChange="isPasswordMatch();" /&gt;
&lt;div id="divCheckPassword"&gt;&lt;/div&gt;
</code></pre>

<p>JavaScript</p>

<pre><code>function isPasswordMatch() {
    var password = $("#txtNewPassword").val();
    var confirmPassword = $("#txtConfirmPassword").val();

    if (password != confirmPassword) $("#divCheckPassword").html("Passwords do not match!");
    else $("#divCheckPassword").html("Passwords match.");


}

$(document).ready(function () {
    $("#txtConfirmPassword").keyup(isPasswordMatch);
});
</code></pre>

我正在做密码匹配的概念，当我在其中输入密码时，它工作得很好，它显示“密码匹配”或“密码不匹配”。但是这里有一个问题，或者可以说是bug之类的东西。当您的密码匹配，然后突然删除框中的两个密码，它仍然显示“密码匹配”或“密码不匹配”。为了更好的理解，我发布了一张图片。​​那么，当两个密码都为空时，如何隐藏或删除“密码不匹配...
