var totalTimes = 0;

var Next = function () {
    var questionId = answer[times]['questionId']
    console.log("questionId", questionId)
    $(`[id$=_${questionId}]`).click();
    setTimeout(
        function () {
            var strAns = answer[times]['answerNo'];
            var arrA = strAns.split('');
            for (a of arrA) {
                console.debug(a);
                $('input[value=' + a + ']').click()
            }
            times += 1;
            if (times < totalTimes) {
                Next();
            }
            else {
                console.debug('完成');
            }
        }, 1000);
};

var start = function () {
    console.debug('开始');
    let cookie = document.cookie;
    let matchArray = cookie.match(/_EXAM(\d+)_PAPER(\d+)_SERIES(\d+)/);
    let examId = matchArray[1];
    let paperId = matchArray[2];
    let seriesId = matchArray[3];
    let answerUrl = `http://www.faxuanyun.com//ess/service/getpaper?paperId=${paperId}&series=${seriesId}_answer`
    fetch(answerUrl, {
        "headers": {
