javascript - 窗口调整大小功能不适用于标题导航

Question

我正在开发一个标题导航，左侧有 Logo ，右侧有个人资料图标，中间有一些导航链接。

有一个左侧滑动菜单，当窗口宽度小于 700px 时触发。我也在窗口调整大小事件上触发了向左滑动菜单。在调整窗口宽度大小时，主导航必须转移到响应式菜单容器。但是它不适用于窗口调整大小功能。

这是 codepen link我试过了

$("#sidebarCollapse").on('click', function () {
  $('#sidebar').toggleClass('active');
});  
$(".main-nav li a").on('click', function(){
  $(".main-nav li a").removeClass('active');
  $(this).addClass('active');
});  
 

// Menu Add Class Left
$(".hamburger-menu").click(function(){
  $(".mob-menu").toggleClass("slide-left");
});  

//  Menu Add Class Close    
$('.mdl-layout__obfuscator').click(function(){
  $(".mob-menu").removeClass("slide-left");
});  

var domWidth = $(window).width();
function moveElements() {
var mobMenu = $('.mob-menu'),
$mainNav = $('.main-nav'),
respNav = $('.resp-nav'),
mainHdr = $(".global-header");
  
if( domWidth < 700) {
  //alert(domWidth);
  $('.main-nav').appendTo('.resp-nav');
}
} . 

$(window).on('load resize',function() {
  // alert('hi');
  moveElements();   
  $(window).resize(function() {
    moveElements();
  });   

});

Answer 1

问题可能是因为这一行只发生了一次:

var domWidth = $(window).width();

您需要将该行代码放在您的 moveElements 函数中，以便它持续检查窗口的宽度。

此外，我建议不要使用“appendTo”来移动某些东西。像这样移动 DOM 的各个部分是很棘手的，你很容易弄得一团糟。最好使用 CSS 来移动某些东西的显示。或者，如果您不能单独使用 CSS 实现它 - 也许有两个实例，并根据需要显示/隐藏它们。
