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。
试试下面的代码:
$('.entry_details').dialog({
width:800,
height:500,
draggable: true,
title: entry.short_description,
closeText: "Zamknij",
open: function(){
// blokowanie scrolla dla body
var body_scroll = $(window).scrollTop();
$(window).on('scroll', function(){
$(document).scrollTop(body_scroll);
});
},
close: function(){
$(window).off('scroll');
}
});
最著名的答案很简单,即。
body{
height: 100%;
overflow-y: hidden;
}
但是,如果你想在子/孙子中打开一个模态并停止滚动,该如何解决呢?更长期的解决方案是使用props或存储在Angular/React中,并改变body标签的高度和溢出属性。
另一种解决方案是从子/孙子组件获取主体,并相应地改变其高度和溢出以停止滚动。
在我的例子中,我只是这样做的
if(isModalExpanded){
document.body.style.overflow = "hidden";
document.body.style.height = "100%";
}
else{
document.body.style.overflow = "auto";
document.body.style.height = "auto";
}
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%;
}

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
这个问题已经解决,
解决方案:只需打开bootstrap .css并按以下方式更改
body.modal-open,
.modal-open .navbar-fixed-top,
.modal-open .navbar-fixed-bottom {
margin-right: 15px;
}
to
body.modal-open,
.modal-open .navbar-fixed-top,
.modal-open .navbar-fixed-bottom {
/*margin-right: 15px;*/
}
