分享好物 B站分集视频教程集数时长统计脚本

可调倍速灵活自由版

步骤

一、在b站找到想看的分集视频

二、在该页面浏览器上方，右击，添加网页

三、复制如下代码，填入 `网址` 处

javascript: (function() {
    var hour = 0;
    var minute = 0;
    var second = 0;
    var txt = document.getElementsByClassName('cur-page')[0].innerHTML;
    var page = txt.match(/\/(\d+)/)[1];
    function f1() {
        hour = 0;
        minute = 0;
        second = 0;
        var min = 0;
        var sec = 0;
        if (document.getElementById('divChild')) {
            d.removeChild(document.getElementById('divChild'));
        }
        if (parseInt(input1.value) >= 1 && parseInt(input1.value) <= page && parseInt(input2.value) <= page && parseInt(input1.value) <= parseInt(input2.value)) {
            for (var i = parseInt(input1.value) - 1; i < parseInt(input2.value); i++) {
                var time = document.getElementsByClassName('duration')[i].innerHTML;
                var t = time.match(/\d+/g);
                if (t.length == 3) {
                    var h = t[0];
                    var m = t[1];
                    var s = t[2];
                } else {
                    var h = 0;
                    var m = t[0];
                    var s = t[1];
                }
                hour += parseInt(h);
                min += parseInt(m);
                sec += parseInt(s);
            }
            hour += parseInt(min / 60);
            minute = min - parseInt(min / 60) * 60 + parseInt(sec / 60);
            second = sec - parseInt(sec / 60) * 60;
            if (minute >= 60) {
                hour += parseInt(minute / 60);
                minute = minute - parseInt(minute / 60) * 60;
            }
            if (second >= 60) {
                minute = parseInt(second / 60);
                second = second - parseInt(second / 60) * 60;
            }
            if (input3.value != 1) {
                var total = hour * 3600 + minute * 60 + second;
                total = total / input3.value;
                hour = parseInt(total / 3600);
                minute = parseInt((total % 3600) / 60);
                second = total % 60;
            }
            var d1 = document.createElement('div');
            d1.style.cssText = "margin-top:15px";

            d1.appendChild(t1);
        } else {
            var d1 = document.createElement('div');
            d1.style.cssText = "margin-top:15px";

    function over() {

})();

四、回到b站，分集视频

五、在该页面(浏览器上方书签栏)，点击刚刚添加的书签

六、即可根据查询播放区间获取视频统计时长

效果图

简单粗暴版

步骤

一、复制代码

var ul = document.querySelector(".cur-list>.list-box"),
  liList = ul.getElementsByTagName("li"), // 获取列表的liList数组
  titleAry = [], // 存放标题
  times = 0, // 存放时间
  timesStr = ""; // 处理时间格式 h:m:s 这种

// 处理（获取）总时长
[].forEach.call(liList, (item) => {
  var a = item.getElementsByTagName("a")[0],
    title = a.title,
    div = a.getElementsByClassName("duration")[0],
    time = div.innerText.replace(
      /(\d+)\:(\d+)/,
      ($0, $1, $2) => Number($1) * 60 + Number($2)
    );
  times += Number(time);
  titleAry.push(title);
});

// 处理时间格式
((_) => {
  var h = parseInt(times / 3600),
    m = parseInt((times - h * 3600) / 60),
    ss = times - h * 3600 - m * 60, // 仅仅是验证秒的正确性
    s = times % 60;
    [h, m, s].forEach((item, index) => {
        item = item < 10 ? "0" + item : item;
        // 让[h, m, s]的最后一位时走esle
        index < 2 ? timesStr += item + ":" : timesStr += item;
   });
})();
console.log(titleAry); // 分P标题
console.log("总时长为：" + times + "S 即：" + timesStr);
