我正在使用带有锚链接的jasny bootstrap非画布菜单,以便在点击时导航到1月部分。当我点击锚链接时,我添加了一个jquery解决方案来关闭画布外菜单。
JQUERY:关闭Off-Canvas菜单并导航到Anchor Link区号:
$('.navmenu-nav li a').on('click', function(){
$(".backdrop").hide( 0, function() {});
$("body").removeClass("bs.offcanvas");});
问题当关闭画布菜单处于活动状态时,上面的代码在992px浏览器宽度下运行良好,但当浏览器宽度超过时 992px关闭画布菜单成为固定的左菜单,但黑色 当我点击锚链接时,仍然会出现背景。我试着用 992px之后的 removeAttr 数据目标和数据切换 宽度没有成功。我仍然是JQuery的新手,我似乎无法做到 想出这个。
在992px宽度后单击锚点链接时,如何防止背景出现?
奖励:当我选择992px宽度后的锚点链接时,菜单似乎也会跳转,如果关闭画布菜单成为固定的左侧菜单,如何防止它跳转?
先决条件:
Bootstrap.min.css
Bootstrap.min.js
jasny-bootstrap.css
jasny-bootstrap.js
JQuery的:
/Close Modal when navigating to anchor */
$('.navmenu-nav li a').on('click', function(){
$(".backdrop").hide( 0, function() {});
$("body").removeClass("bs.offcanvas");
});
/Simulate Modal Opening */
$(".nav-link").click(function() { $("#navToggle").click() })
$('.navmenu').on('show.bs.offcanvas', function() {
$('.backdrop').fadeIn();
});
$('.navmenu').on('hide.bs.offcanvas', function() {
$('.backdrop').fadeOut();
});
/Close Modal on Resize */
$(window).resize(function() {
if ($(window).width() > 992) {
$(".backdrop").hide( 0, function() {});
$("body").removeClass("bs.offcanvas");
}
});

我已经对你的小提琴进行了一些修改,现在你可以检查它here。我想我已经解决了,现在它正在做你想做的事。
请在此处查看jQuery代码:
let Vehicle = {
debug() {
return 'Vehicle';
}
};
let Car = {
debug() {
return super.debug() + ' is a Car';
}
};

您可以使用媒体查询单独使用CSS解决此问题,并使用!important
强制优先于jquery插件的内联样式
@media (min-width: 992px) {
.backdrop {
display: none!important;
}
}
