纯js实现判断ip是否ping通

最近在做一个需求时要考虑到网络环境是否能够访问，于是写了一段代码

    function ping(address) {
    
      var img = new Image();
      var start = new Date().getTime();
      var hasFinish = false;
      img.onload = function() {
    
        if ( !hasFinish ) {
    
          hasFinish = true;
          console.log('Ping ' + address + ' success. ');
        }
      };
      img.onerror = function() {
    
          hasFinish = false;
          console.log('Ping ' + address + ' fail.. ');
      };
      img.src = address + '/?' + start;
      setTimeout(()=>{
    
        if(hasFinish){
    
          hasFinish = false
          console.log('There is a problem with your network, please refresh the page and try again.');
        }
      },1500)
    }
