当模式打开时，防止BODY滚动 - Code

我想让我的身体在使用鼠标滚轮时停止滚动，而我的网站上的Modal(来自http://twitter.github.com/bootstrap)是打开的。

当模式被打开时，我试图调用下面的javascript片段，但没有成功

$(window).scroll(function() { return false; });

AND

$(window).live('scroll', function() { return false; });

请注意，我们的网站放弃了对IE6的支持，IE7+需要兼容。

对于Bootstrap，你可以尝试这样做(在Firefox, Chrome和Microsoft Edge上工作):

body.modal-open {
    overflow: hidden;
    position:fixed;
    width: 100%;
}

这个解决方案对我很有效:

var scrollDistance = 0; $(document).on("show.bs.modal", ".modal", function () { scrollDistance = $(window).scrollTop(); $("body").css("top", scrollDistance * -1); }); $(document).on("hidden.bs.modal", ".modal", function () { $("body").css("top", ""); $(window).scrollTop(scrollDistance); }); .content-area { height: 750px; background: grey; text-align: center; padding: 25px; font-weight:700; font-size: 30px; } body.modal-open { position: fixed; left: 0; width: 100%; } <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.css" rel="stylesheet"/> <script src="https://code.jquery.com/jquery-3.4.1.slim.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.js"></script> <div class="content-area"> Scroll Down To Modal Button<br/> <svg xmlns="http://www.w3.org/2000/svg" width="56" height="56" fill="currentColor" class="bi bi-arrow-down" viewBox="0 0 16 16"> <path fill-rule="evenodd" d="M8 1a.5.5 0 0 1 .5.5v11.793l3.146-3.147a.5.5 0 0 1 .708.708l-4 4a.5.5 0 0 1-.708 0l-4-4a.5.5 0 0 1 .708-.708L7.5 13.293V1.5A.5.5 0 0 1 8 1z"/> </svg> </div> <center class="my-3"> <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal"> Launch demo modal </button> </center> <div class="content-area"></div>  <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal title</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span> </button> </div> <div class="modal-body"> <p>Cras mattis consectetur purus sit amet fermentum.

基本上，当打开模态时，它会为主体添加一个负顶部，以在打开模态之前保持窗口滚动位置。关闭模态时，窗口滚动保持使用相同的值应用于顶部时，打开。这种方法可以防止身体滚动。

这是一把能用的小提琴

对于那些使用SharePoint 2013的人，有一个小提示。主体已经有overflow: hidden。你要找的是设置overflow:隐藏在id为s4-workspace的div元素上，例如。

var body = document.getElementById('s4-workspace');
body.className = body.className+" modal-open";

你可以试着设置body size为window size, overflow:当modal打开时隐藏

这招对我很管用:

$("#mymodal").mouseenter(function(){
   $("body").css("overflow", "hidden"); 
}).mouseleave(function(){
   $("body").css("overflow", "visible");
});

   $('.modal').on('shown.bs.modal', function (e) {
      $('body').css('overflow-y', 'hidden');
   });
   $('.modal').on('hidden.bs.modal', function (e) {
      $('body').css('overflow-y', '');
   });
