sessionStorage 存值出现刷新值消失

function clearTimeoutAll(call_name) {
  sessionStorage.setItem("last_call", call_name);
  console.log(call_name);
  $("#orderkantip").hide();
  for (var i = 0; i < timeouts.length; i++) {
    clearTimeout(timeouts[i]);
  }
  timeouts = [];


  /*    setTimeout("autoClickMaue()",5000);  */
}


function load_history_overviw(start, end) {
  clearTimeoutAll(arguments.callee.name);
  $("#kanbanID").empty();
  if (start != null) {
    sessionStorage.setItem("t0", start);
    sessionStorage.setItem("t1", end);
  }


  $("#kanbanID").load("productStatus/twoDetail.jsp");
}只需对参数进行非空判断即可
