青果教务系统适配小爱课程表

前言：

课程表的适配主要是对dom层的提取归类处理，本人技术水平较低，这里简单分享下自己的代码

仓库地址小爱课程表

过程：

课程表的适配主要是通过操作scheduleHtmlProvider，scheduleHtmlParser，scheduleTimer函数完成的，他们的作用分别是获取dom，处理dom，设置课表节次时间。

首先获取课程表内容，这里我使用js获取接口内容。

scheduleHtmlProvider函数：

function scheduleHtmlProvider(iframeContent = "", frameContent = "", dom = document) {
    var xhr = new XMLHttpRequest();
    xhr.open('GET', 'http://jwgl.hist.edu.cn/wsxk/xkjg.ckdgxsxdkchj_data10319.jsp?params=eG49MjAyMiZ4cT0wJnhoPTIwMjEwMDAwNTExMg==', false);
    xhr.send();
    return xhr.responseText;

}

scheduleHtmlParser函数：

function scheduleHtmlParser(html){
    let course = [];
    const $ = cheerio.load(html, {decodeEntities: false}); // 避免中文乱码
    $(' tbody>tr ').each(function () {
        //大杂烩
        var name = $(this).eq(0).children(":eq(1)").text();
        //这是课程名字
        console.log("name"+name)
        var teacher = $(this).eq(0).children(":eq(5)").text();
        //这是教师名字
        var allData = $(this).eq(0).children(":eq(8)").text();
        //数据位置大杂烩
        var sumTime = allData.split(",");
        var sumLength = sumTime.length;
        //时间个数
        console.log("输出时间个数:"+sumLength);


        if (sumLength == 1) {

            console.log("allTime"+allTime)

            //在这里提前取出来单双周
            var flag = 0;

            if (sumTime[0].search("单")!=-1){
                flag = 1;
