javascript - 响应式侧边栏推送菜单

Question

我有一个关于响应式侧边栏菜单的问题。首先我会给你一个 DEMO 来自 codepen.io

如果您更改浏览器宽度，那么您可以在右上角看到绿色按钮。当您单击此按钮时，红色背景颜色的 div 将打开。但与此同时，如果您将 bowser 宽度从 640px 更改为 900px，则红色 div 不会返回原始区域。

我该如何修复它，有人可以在这方面帮助我吗？

HTML

<div class="test_container">
  <div class="left">
      <div class="left_in"><div class="aa">ss</div></div>
  </div>
  <div class="r click_open_close">Click To Show Slide sLeft In</div>
  <div class="right"><div class="bb"></div></div>
</div>

JS

$('.click_open_close').click(function() {
  $('.left').animate({
    left: "0%"
  }, 200);
  $('.right').animate({
    right: "-30%"
  }, 200);
});

Answer 1

试试这个

 $(document).ready(function(e) {

 $('.click_open_close').click(function() {
   $('.left').animate({
     left: "0%"
   }, 200);
 });

 });

 $(window).resize(function(e) {
     var windoww = $(window).width();
     if(windoww < 840){
         location.reload(); //or set whatever animation you want to do for the sidebar gets back in place
     };
 });
