实现原理，监听 storage

 // 监听 storage 变化
          window.addEventListener('storage',   (e)=>{
            console.log('e:',e)
            if (e.key === 'xxxx') {
                const params = JSON.parse(e.newValue);
         
            }
        });

触发 storage，这里必须 window.localStorage.setItem 才生效

   window.localStorage.setItem('xxxx',JSON.stringify({
               name:'1111',
              age:'18'
            }))
