打开移动菜单时如何禁用后台滚动? [英] How to disable scrolling in the background when the mobile menu is open?

问题描述

我正在建立一个具有导航菜单的移动响应网站. 当我到达菜单底部时-如果在到达菜单底部时继续滚动-它将在后台滚动页面. 如何禁用它?

I am building a mobile responsive website that has a nav menu. When I get to the bottom of the menu - If I continue scrolling when I reach the bottom of the menu - it scrolls the page in the background. How can I disable it?

到目前为止，这是我的jQuery代码:

This is my jQuery code so far:

// When the document is loaded...
$(document).ready(function() {

    $('#mob-menu-btn').click(function(){
        $('.sports').slideToggle("slow");
    })

    $('#sub-menu').click(function(){
        $('.sports2').slideToggle("slow");
    })

});

这是我的CSS:

    .list{
        width: 100%;
        overflow: hidden;
        overflow-y: auto;
        top: -10%;
        overflow: hidden;
        overflow-y: auto;
}


    .sports li{
        list-style-image:none;
        list-style-type: none;
        border-bottom: 2px solid #eeeeee;
        margin-bottom: 0px; 
        margin-left: 0px; 
        padding-top: 15px;
        padding-bottom: 15px;
        padding-left: 10px;
        width:100%;
        font-family: arial;
        text-decoration: none;
        overflow: hidden;
    }

推荐答案

打开菜单时，将位置设置为固定在主体上.当您关闭它时，请删除该属性.最好使用添加/删除类.

When menu is open, set position fixed to the body. When you close it, remove that property. Better use add/remove class.

 if($('#mob-menu').is(':visible'))
 {
    $('body').addClass("fixedPosition");
 }
 else
 {
    $('body').removeClass("fixedPosition");
 }

 .fixedPosition
 {
    position: fixed;
 }
