how to make password textbox value visible when ho

Good day all,

I have a form that has a password field:

<input type="password" name="password" size="30" />

Naturally, the input text will be replaced by (*).

So if the user typed 123 the box will show ***.

Up to here, it is straight forward, but...

Now, I wanna add a small icon next to the password box so when the user hover over this icon, he can see what he has entered so far.

So, while hovering, the box will show 123 and when the user leaves the icon the box should show *** again.

Is there any way to do this with JavaScript? Also, I am using HTML and PHP.

EDIT:

It really doesn't need to be an icon, it could be a checkbox or a button... AND if it could be done in CSS, I would really appreciate to know how

P.S. I've googled and search the stackoverflow but with no luck

Try This :

In HTML and JS :

// Convert Password Field To Text On Hover.
  var passField = $('input[type=password]');
  $('.show-pass').hover(function() {
      passField.attr('type', 'text');
  }, function() {
    passField.attr('type', 'password');
  })
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>
<!-- An Input PassWord Field With Eye Font-Awesome Class -->
<input type="password" placeholder="Type Password">
      <i class="show-pass fa fa-eye fa-lg"></i>

Its simple javascript. Done using toggling the type attribute of the input. Check this http://jsfiddle.net/RZm5y/16/

a rapid response not tested on several brosers, works on gg chrome / win

-> On focus event -> show/hide password

<input type="password" name="password">

script jQuery

// show on focus
$('input[type="password"]').on('focusin', function(){

    $(this).attr('type', 'text');

});
// hide on focus Out
$('input[type="password"]').on('focusout', function(){

    $(this).attr('type', 'password');

});

1 minute googling gave me this result. See the DEMO!

HTML

<form>
    <label for="username">Username:</label>
    <input id="username" name="username" type="text" placeholder="Username" />
    <label for="password">Password:</label>
    <input id="password" name="password" type="password" placeholder="Password" />
    <input id="submit" name="submit" type="submit" value="Login" />
</form>

jQuery

// ----- Setup: Add dummy text field for password and add toggle link to form; "offPage" class moves element off-screen
$('input[type=password]').each(function () {
    var el = $(this),
        elPH = el.attr("placeholder");
    el.addClass("offPage").after('<input class="passText" placeholder="' + elPH + '" type="text" />');
});
$('form').append('<small><a class="togglePassText" href="#">Toggle Password Visibility</a></small>');

// ----- keep password field and dummy text field in sync
$('input[type=password]').keyup(function () {
    var elText = $(this).val();
    $('.passText').val(elText);
});
$('.passText').keyup(function () {
    var elText = $(this).val();
    $('input[type=password]').val(elText);
});

// ----- Toggle link functionality - turn on/off "offPage" class on fields
$('a.togglePassText').click(function (e) {
    $('input[type=password], .passText').toggleClass("offPage");
    e.preventDefault(); // <-- prevent any default actions
});

CSS

.offPage {
    position: absolute;
    bottom: 100%;
    right: 100%;
}
