How to implement the back force refresh function on WeChat web side (detailed tutorial)

This article mainly introduces the implementation code of the back force refresh function on the WeChat web side. Friends who need it can refer to it

The specific code is as follows:

<script>
  //生成uuid
  var uuidChars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz".split("");
  function uuid() {
    var r;
    var uuid = [];
    uuid[8] = uuid[13] = uuid[18] = uuid[23] = "-";
    uuid[14] = "4";
    for (i = 0; i < 36; i++) {
      if (!uuid[i]) {
        r = 0 | Math.random() * 16;
        uuid[i] = uuidChars[(i == 19) ? (r & 0x3) | 0x8 : r];
      }
    }
    return uuid.join("");
  }
  // 兼容 android
  history.replaceState(null, null, "/currentURL?a="+uuid());
  // 兼容 ios
  $(function () { 
     var isPageHide = false; 
     window.addEventListener(&#39;pageshow&#39;, function () { 
      if (isPageHide) { 
       window.location.reload(); 
      } 
     }); 
     window.addEventListener(&#39;pagehide&#39;, function () { 
      isPageHide = true; 
     }); 
  })
</script>

•The history object in h5 used by the android side, history.replaceState(null, null, "/currentURL?a=" uuid()); changes after the page is loaded The current url (spliced ​​with a uuid or random number), so that every time you go back, the browser will reload if it finds that the current url does not exist in the browser cache.
•But the ios side does not support the above method, so I used a piece of jquery code to solve it.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
