The Bootstrap modal causes the scrollbar to vanish upon closure

Despite trying numerous solutions and hacks on this issue from StackOverflow, none of them seem to work for me.

Currently, I am utilizing a modal for the login process in Meteor (e.g. using Facebook login service) which triggers a callback upon successful login.

In my callback function, I have included the following line to close the modal:

$('#modalSignIn').modal('toggle');

While everything seems to be functioning correctly, one problem persists - after closing the modal, the page lacks a scrollbar.

One potential remedy suggested was found here -

.modal-open {
    overflow: scroll;
}

This solution works partially as it maintains the scrollbar even when the modal is closed. However, there appears to be approximately 15px padding on the right side (where the previous scrollbar should be). Upon repeated opening and closing of the modal, this padding continues to accumulate.

EDIT:

Below is my Nav template -

<template name="_navMenu">
    {{#if isLoggedIn}}
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">My Profile <span class="caret"></span></a>
          <ul class="dropdown-menu" role="menu">
            <li><a href="#">My Profile</a></li>
            <li><a href="#">Edit Profile</a></li>
            <li class="divider"></li>
            <li><a href="#" id="logout-button">Logout</a></li>
          </ul>
        </li>
    {{else}}
        <li><a href="#" data-toggle="modal" data-target="#modalSignUp">SIGN UP</a></li>
        <li><a href="#" data-toggle="modal" data-target="#modalSignIn">LOG IN</a></li>
        <li><button class="btn btn-primary nav-button visible-xs-inline-block">Text Here</button></li>

        <!-- Modal -->
        <div class="modal fade" style="overflow-y: scroll;" id="modalSignIn" tabindex="-1" role="dialog" aria-labelledby="SignInLabel" aria-hidden="true">
          <div class="modal-dialog">
            <div class="modal-content">
              <div class="row">
                  <div class="col-xs-8 col-xs-offset-2">
                    {{> atFormModal state="signIn"}}
                  </div>
              </div>
            </div>
          </div>
        </div>
    {{/if}}
</template>

Answer №1

Encountered a similar issue where Bootstrap was adding the modal-open class to the body but failing to remove it when the modal was closed. I managed to resolve this by including the following callback:

$('body').removeClass('modal-open');

Answer №2

If you're experiencing issues, give this solution a shot:

$(document).on('hidden.bs.modal', '.modal', function () {
    $('.modal:visible').length && $(document.body).addClass('modal-open');
});

Answer №3

Check the body and html tags in your code; one of them may have acquired an inline style of overflow:hidden.

To fix this, update your CSS file with the following:

body {
  overflow: auto !important;
}

Alternatively, you can use:

html {
  overflow: auto !important;
}

I also noticed that it adds a padding-right style, which you may want to remove as well.

Answer №4

Don't forget to include the following in your body element style="overflow:auto;"

Answer №5

 $('html').removeClass("modal-open");

// The Bootstrap framework adds the modal-open class to the body element, which needs to be manually removed when the modal is closed for proper functionality.

Answer №6

Eliminate the scroll bar problem by including the following in your body CSS style.

I encountered the same issue and none of the solutions provided helped, so I took a different approach and realized that explicitly setting the CSS rule would guarantee the desired outcome.

body { padding-right: 0!important }

Answer №7

Here's the solution that worked for me:

$("body").css("overflow", "auto");

Answer №8

After identifying the issue, I wanted to share it in case others encounter the same problem. The modals were placed within an {{#if }} statement, causing them to disappear once a user logs in. By removing the modals from the if statement, the issue was resolved.

<template name="_navMenu">
    {{#if isLoggedIn}}
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false>My Profile <span class="caret"></span></a>
          <ul class="dropdown-menu" role="menu">
            <li><a href="#">My Profile</a></li>
            <li><a href="#">Edit Profile</a></li>
            <li class="divider"></li>
            <li><a href="#" id="logout-button">Logout</a></li>
          </ul>
        </li>
    {{else}}
        <li><a href="#">HOW IT WORKS</a></li>
        <li><a href="#" data-toggle="modal" data-target="#modalSignUp">SIGN UP</a></li>
        <li><a href="#" data-toggle="modal" data-target="#modalSignIn">LOG IN</a></li>
        <li><button class="btn btn-primary nav-button visible-xs-inline-block">Text Here</button></li>
    {{/if}}

    <!-- Modal -->
    <div class="modal fade" style="overflow-y: scroll;" id="modalSignIn" tabindex="-1" role="dialog" aria-labelledby="SignInLabel" aria-hidden="true">
      <div class="modal-dialog">
        <div class="modal-content">
          <div class="row">
              <div class="col-xs-8 col-xs-offset-2">
                {{> atFormModal state="signIn"}}
              </div>
          </div>
        </div>
      </div>
    </div>

</template>
