javascript - After clicking the physical return button on the phone on the WeChat page, does the page click event fail?

During the development process of the WeChat public account site, a page was cyclically bound to a click event. After switching to another page and returning through the physical return key of the phone, the click event became invalid. I don’t know why?

<code>$(function(){
  //点击事件
  var mapList=$(".map .loc-tag");
  $.each(mapList,function(index,item){
      mapList.eq(index).on('click',function(){
         ...
         //get请求
      });
  });
});</code>

Try event delegation

var hastouch = "ontouchstart" in window ? true : false,
start = hastouch ? "touchstart" : "click";

mapList.eq(index).on(start,function(){

<code>     ...
     //get请求</code>

});

I also encountered this problem when I was working on a project before.
