//开始计时

初始化加载
写在table的done里面
  var table_sends= JSON.parse(localStorage.getItem('table_send_index')) || [];

                for(var i=0;i<table_sends.length;i++) {
                    var timerss=localStorage.getItem('timer_button_'+table_sends[i]);
                    if (timerss) {
                        startTimers(table_sends[i],parseInt(timerss))
                    }
                }
...

事件加载
```js
 if (layEvent == 'send_datas') {

                //startTimers
                

                var data_index=$(tr).attr("data-index");

                //定义总的数据组
                var table_send_index= JSON.parse(localStorage.getItem('table_send_index')) || [];
                table_send_index.push(data_index);
                localStorage.setItem('table_send_index', JSON.stringify(table_send_index));
            

                startTimers(data_index,120);
}
