Question

嗨我正在显示一个模式，当人打开我的网站工作正常但是当用户关闭时，模态开放课程不会被删除，不允许他们滚动。

    <div id="ageModal" class="modal fade" data-backdrop="static" data-keyboard="false" role="dialog" style="padding-right: 0px;">
    <div class="modal-dialog">
    <!-- Modal content-->
    <div class="modal-content" style="background-color: #c9c9f8;" >
            <div class="modal-header">
                <button type="button" class="close hide" data-dismiss="modal">&times;</button>

            </div>
            <div class="modal-body text-center" style="padding-top:10%">
               <h1>hi</h1>
                <div>
                    <button type="button" class="btn btn-default" id="ageVerifyYes">Yes</button>
                    <button type="button" class="btn btn-default" id="ageVerifyNo">No</button>
                </div>
                <div>
                    <input type="checkbox" id="rememberMeAge"> Remember Me
                </div>
                <div id="ageVerifyError" class="hide">
                    <p class="error-msg">You should agree</p>
                </div>
            </div>
            <div class="modal-footer hide">
                <button type="button" class="btn btn-default" data-dismiss="modal">Yes</button>
                <button type="button" class="btn btn-default">No</button>
            </div>
        </div>
    </div>
</div>
    <style type="text/css">
#ageModal .modal-dialog {
    width: 100%;

#ageModal .error-msg{
    color: #c00;
    padding: 10px;
}
.in{
    padding:0px!important;
}
</style>




<script type="text/javascript">

$(document).ready(function() {



    var isshow = sessionStorage.getItem('isshow');
if (isshow == null || isshow == '') {
    sessionStorage.setItem('isshow', 1);
    // Show popup here
    $('#ageModal').show();
}
else{
        //hide popup if opened once
        $('#ageModal').hide();
        $('.fade').hide();
    }
});

$('#ageVerifyNo').on('click', function(){
    $('#ageVerifyError').removeClass('hide');
});

$('#ageVerifyYes').on('click', function(){
    if($('#rememberMeAge').prop('checked') === true){
        setCookie('ageVerified',1,1);
    }
    $('#ageModal').modal('hide');
    $("body").removeClass("modal-open");
});

function setCookie(name,value,days) {

    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days*24*60*60*1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + (value || "")  + expires + "; path=/";
}

function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

function eraseCookie(name) {   
    document.cookie = name+'=; Max-Age=-99999999;';  
}

如果弹出窗口打开与否，我基本上会在会话中存储。它按预期工作，但即使在模态关闭后，模态打开类仍保留body标签。我确实试过$（＆＃34; body＆＃34;）。removeClass（＆＃34; modal-open＆＃34;）;但没有运气我也创造了另一个，并试图追加到那里，但同样的问题。因为我正在使用cdn

，所以无法编辑引导程序

Answer 1

试试这个

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

Answer 2

作为替代的快速解决方案，只需从
fade中删除<div id="ageModal" class="modal fade"...类。
此问题可能是由于在淡入淡出动画完全完成之前调用了modal（'hide'）

Answer 3

您的.show()和.hide()应为.modal('show')和.modal('hide')

Answer 4

ngDoCheck(){
        var x = $(document).find('.modal.show').length;
        if(x>0) {
            $('body').addClass('modal-open');
        } else {
            $('body').removeClass('modal-open');
        }

      }

modal-open不会从中删除
