jquery – 删除模式背景之后某些浏览器大小(jasny bootstrap)

我正在使用带有链接链接的jasny bootstrap off-canvas菜单,以便浏览到点击的一月部分.当我点击锚点链接时,我添加了一个 jquery解决方案来关闭帆布外菜单.

JQUERY：关闭帆布菜单并导航到锚链接区域代码：

$('.navmenu-nav li a').on('click',function(){
   $(".backdrop").hide( 0,function() {});
    $("body").removeClass("bs.offcanvas");});

Problem The above code works great under 992px browser width when the off canvas menu is active,but when the browser width goes past
992px the off canvas menu becomes a fixed left menu,but the black
backdrop still appears when I click on the anchor link. I tried to use
the removeAttr data-target and data-toggle after 992px
width without success. I’m still very new at JQuery and I can’t seem
to figure this out.

当我在992px宽度上点击锚链接后,可以做什么来防止背景出现？

奖金：当我在992px宽度之后选择一个锚点链接时,菜单也似乎跳了起来,当关闭画布菜单变成固定的左侧菜单时,如何防止跳转？

JQuery的：

/Close Modal when navigating to anchor   */
$('.navmenu-nav li a').on('click',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");

 }
});

解决方法

我在你的小提琴中做了一些改变,现在你可以查看它 here.我想我已经解决了,现在它正在做你想要的.

>如果窗口宽度大于992,导航点击覆盖不会显示
>如果窗口宽度小于或等于992,它将按原样工作

请参阅jQuery代码：

// simulate modal opening
$('.nav-link').click(function(e) {
  if ($(window).width() > 992) {
    $('.backdrop').hide(0,false);
  }
  
	$('#navToggle').click();
});

$('.navmenu').on('show.bs.offcanvas',function() {
  if ($(window).width() <= 992) {
    $('.backdrop').fadeIn();
  }
});

$('.navmenu').on('hide.bs.offcanvas',function() {
  if ($(window).width() <= 992) {
    $('.backdrop').fadeOut();
  }
});


// close modal on resize
$(window).resize(function() {
  if ($(window).width() > 992) {
    $('.backdrop').hide(0,false);
    $('body').removeClass('bs.offcanvas');
  }
});

// switch active navigation link onclick
$('.nav a').on('click',function() {
  $('.nav').find('.active').removeClass('active');
  $(this).parent().addClass('active');
});

// close Modal when navigating to anchor
$('.navmenu-nav li a').on('click',function() {
  $('.backdrop').hide(0,false);
  $('body').removeClass('bs.offcanvas');
});
