sessionStorage 刷新 传值消失

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");
}


只需对参数进行判断不为空就行
