火车票 节点操作


查找车次

function c(i){console.log(i);};ia=document.getElementsByClassName("number");len=ia.length;ti=0;for(var i=0;i<len;i++){if(ia[i].childNodes[0].nodeValue=="K457"){ti=i;};};c(ti);
车片预订
document.getElementsByClassName("no-br")[10].childNodes[0].click();
合并
function c(i){console.log(i);};ia=document.getElementsByClassName("number");len=ia.length;ti=0;for(var i=0;i<len;i++){if(ia[i].childNodes[0].nodeValue=="K457"){ti=i;};};c(ti); try{document.getElementsByClassName("no-br")[ti].childNodes[0].click();}catch(err){}

window.reload();


document.getElementById("fromStationText").value="长沙";
document.getElementById("toStationText").value="柳州";
document.getElementById("train_date").value="2018-02-10";
#一般第一次显示“查询超时”
document.getElementById("query_ticket").click();
function c(i){console.log(i);};ia=document.getElementsByClassName("number");len=ia.length;ti=0;for(var i=0;i<len;i++){if(ia[i].childNodes[0].nodeValue=="K457"){ti=i;};};c(ti); try{document.getElementsByClassName("no-br")[ti].childNodes[0].click();}catch(err){}

function gen_random_int(max){return Math.ceil(Math.random()*max);};function sleep(numberMillis) { var now = new Date(); var exitTime = now.getTime() + numberMillis; while (true) { now = new Date(); if (now.getTime() > exitTime) return; } };function sleep_max(max){numberMillis=gen_random_int(max);sleep(numberMillis);}

sleep(1000*60*3);
window.reload();

可以预定
document.getElementsByClassName("no-br")[10].childNodes[0].length==undefined

以下  没实现效果

// https://kyfw.12306.cn/otn/leftTicket/init
function c(i) {
    console.log(i);
};

function gen_random_int(max) {
    return Math.ceil(Math.random() * max);
};

function sleep(numberMillis) {
    var now = new Date();
    var exitTime = now.getTime() + numberMillis;
    while (true) {
        now = new Date();
        if (now.getTime() > exitTime) return;
    }
};

function sleep_max(max) {
    numberMillis = gen_random_int(max);
    sleep(numberMillis);
}

while (true) {
    document.getElementById("fromStationText").value = "长沙";
    document.getElementById("toStationText").value = "柳州";
    document.getElementById("train_date").value = "2018-02-10";

    for (var i = 0; i < 4; i++) {
        document.getElementById("query_ticket").click();
        sleep(1000 * 60 * 1);
        sleep_max(1000 * 60 * 1);
    }

    ia = document.getElementsByClassName("number");
    len = ia.length;
    ti = 0;
    for (var i = 0; i < len; i++) {
        if (ia[i].childNodes[0].nodeValue == "K457") {
            ti = i;
        }
        ;
    }

    c(ti);
    if (document.getElementsByClassName("no-br")[ti].childNodes[0].length == undefined) {
        try {
            document.getElementsByClassName("no-br")[ti].childNodes[0].click();
            break;
        } catch (err) {
        }
    } else {
        c("暂时无票");
    }

    sleep(1000 * 60 * 1);
    sleep_max(1000 * 60 * 3);
    window.location.reload();
}




以下ok

window.setInterval(function () {

    document.getElementById("fromStationText").value = "长沙";
    document.getElementById("toStationText").value = "柳州";
    document.getElementById("train_date").value = "2018-02-10";

    for (var i = 0; i < 3; i++) {
        document.getElementById("query_ticket").click();
    }

    ia = document.getElementsByClassName("number");
    len = ia.length;
    ti = -1;
    for (var i = 0; i < len; i++) {
        if (ia[i].childNodes[0].nodeValue == "K457") {
            ti = i;
        }
    }
    if (ti != -1 && document.getElementsByClassName("no-br")[ti].childNodes[0].length == undefined) {
        try {
            document.getElementsByClassName("no-br")[ti].childNodes[0].click();
        } catch (err) {
        }
    } else {
        console.log("暂时无票");
    }
}, 1000 * 30);

添加随机数


















window.setInterval(function () {

    document.getElementById("fromStationText").value = "长沙";
    document.getElementById("toStationText").value = "柳州";
    document.getElementById("train_date").value = "2018-02-10";

    // for (var i = 0; i < 3; i++) {
    document.getElementById("query_ticket").click();
    // }

    ia = document.getElementsByClassName("number");
    len = ia.length;
    ti = -1;
    for (var i = 0; i < len; i++) {
        if (ia[i].childNodes[0].nodeValue == "K457") {
            ti = i;
        }
    }
    if (ti != -1 && document.getElementsByClassName("no-br")[ti].childNodes[0].length == undefined) {
        try {
            document.getElementsByClassName("no-br")[ti].childNodes[0].click();
        } catch (err) {
        }
    } else {
        console.log("暂时无票");
    }
}, 1000 * 30);
