上海交通大学自动评教脚本(Auto Grade）

Warning (2022/5/14)

现在教学信息服务网有检测脚本功能，每门课可以自动选客观题/填主观题，但是需要手动点击提交。

评教脚本使用指南

已知问题

• 脚本暂时不支持自动翻页，i.e.只支持自动评价前15门课，第二页之后的还是要手动评教。如果有需求，请在issue中提出。
• 如果用户网络延迟过高，可能导致脚本无法正常工作。

脚本概述

本脚本有两个版本：

• 全自动：开始运行后，所有的主观题会自动填入教师姓名+“老师辛苦了”，不需要做任何额外操作。如果你想要默认填入其他内容，在代码中搜索“老师辛苦了”，替换成其他内容即可。
• 半自动：用户需要手动输入每门课的主观题内容，浏览器会使用对话框提示用户何时输入。在一门课评教完成后，用户必须手动确认“评教成功”才能继续。

第一步

进入你的学生评价界面。

第二步

如果您想使用全自动版本，请复制如下代码：

var ungraded;
var numOfUngraded = $('tr:contains("未评")').length;

function waitForAppearance(element, callBack) {
    if($(".alert-modal").length) {
        return;
    }
    window.setTimeout( function() {
        if($(element).length){
            if(element == 'div.col-sm-8:contains("当前评价课程为")') {
                autoGrade();
            } else {
                waitForDisappearance();
            }
        }else{
            waitForAppearance(element, callBack);
        }
    }, 200);
}

function waitForDisappearance() {
    window.setTimeout( function() {
        if($(".success-modal").length == 0) {
            waitForRefresh();
        } else {
            waitForDisappearance();
        }
    }, 200);
}

function waitForRefresh() {
    window.setTimeout( function() {
        var num = $('tr:contains("未评")').length;
        if(num != numOfUngraded) {
            numOfUngraded = num;
            gotoNext();
        } else {
            waitForRefresh();
        }
    }, 5000);
}

function gotoNext() {
    ungraded = $('tr:contains("未评"):first');
    if(ungraded.length == 0) return;

    $("#tempGrid").setSelection(ungraded.attr("id"));

    waitForAppearance('div.col-sm-8:contains("当前评价课程为")', autoGrade);
}

function autoGrade() {
    $(".input-xspj-1 label input").prop("checked",true);
    let pjContent = $('#jsxm').html() + "老师辛苦了！";
    $("textarea.input-zgpj").text(pjContent);
    $("#btn_xspj_tj").click();
    $('#btn_ok').click();
    waitForRefresh();
}

gotoNext();

如果您想使用半自动版本，请复制如下代码：

var ungraded;
var numOfUngraded = $('tr:contains("未评")').length;

function waitForAppearance(element, callBack) {
    if($(".alert-modal").length) {
        return;
    }
    window.setTimeout( function() {
        if($(element).length){
            if(element == 'div.col-sm-8:contains("当前评价课程为")') {
                autoGrade();
            } else {
                waitForDisappearance();
            }
        }else{
            waitForAppearance(element, callBack);
        }
    }, 200);
}

function waitForDisappearance() {
    window.setTimeout( function() {
        if($(".success-modal").length == 0) {
            waitForRefresh();
        } else {
            waitForDisappearance();
        }
    }, 200);
}

function waitForRefresh() {
    window.setTimeout( function() {
        var num = $('tr:contains("未评")').length;
        if(num != numOfUngraded) {
            numOfUngraded = num;
            gotoNext();
        } else {
            waitForRefresh();
        }
    }, 5000);
}

function gotoNext() {
    ungraded = $('tr:contains("未评"):first');
    if(ungraded.length == 0) return;

    $("#tempGrid").setSelection(ungraded.attr("id"));

    waitForAppearance('div.col-sm-8:contains("当前评价课程为")', autoGrade);
}

function autoGrade() {
    $(".input-xspj-1 label input").prop("checked",true);
    let courseInfo = $('div.col-sm-8:contains("当前评价课程为")').text();
    courseInfo = courseInfo.substring(courseInfo.indexOf("当前"), courseInfo.indexOf(";"))
    $("textarea.input-zgpj").text(prompt(courseInfo + "，主观题填什么？"));
    $("#btn_xspj_tj").click();
    waitForAppearance(".success-modal", waitForDisappearance);
}

gotoNext();

第三步

回到学生评价界面，打开浏览器的控制台。如果您不知道快捷键，请右键点击页面空白处，在弹出菜单中点击检视/Inspect或含义类似的选项（因浏览器而异）。然后，会有一个内嵌窗口从您浏览器中弹出，在顶部的水平菜单中选择Console。

第四步

将代码粘贴到下方的输入框中。再按下回车键。

第五步

开始评教。目前脚本不会在评教结束时提示用户。如果想要终止自动评教，请刷新页面。

User Guide

Known issues

• This script only works for the first page of courses, namely the first 15 courses.
• The script might not work properly under unstable or extremely laggy network conditions.

Overview

There are two versions of the script:

• Auto: This version will automatically grade all ungraded courses non-stop, filling in the "主观题" section with pre-defined text. The default text is 教师姓名 + "老师辛苦了！". If you want something else, search for 老师辛苦了 in the code and replace it.
• Semi-auto: This version wil lnot automatically fill in the "主观题" section: a prompt will pop up asking you to fill in whatever you want to say about the course. And after grading a course, you will have to confirm "提交成功" in order to proceed.

Step 1

Enter "Students evaluation" page.

Step 2

For the auto version, copy the code snippet below:

var ungraded;
var numOfUngraded = $('tr:contains("未评")').length;

function waitForAppearance(element, callBack) {
    if($(".alert-modal").length) {
        return;
    }
    window.setTimeout( function() {
        if($(element).length){
            if(element == 'div.col-sm-8:contains("当前评价课程为")') {
                autoGrade();
            } else {
                waitForDisappearance();
            }
        }else{
            waitForAppearance(element, callBack);
        }
    }, 200);
}

function waitForDisappearance() {
    window.setTimeout( function() {
        if($(".success-modal").length == 0) {
            waitForRefresh();
        } else {
            waitForDisappearance();
        }
    }, 200);
}

function waitForRefresh() {
    window.setTimeout( function() {
        var num = $('tr:contains("未评")').length;
        if(num != numOfUngraded) {
            numOfUngraded = num;
            gotoNext();
        } else {
            waitForRefresh();
        }
    }, 5000);
}

function gotoNext() {
    ungraded = $('tr:contains("未评"):first');
    if(ungraded.length == 0) return;

    $("#tempGrid").setSelection(ungraded.attr("id"));

    waitForAppearance('div.col-sm-8:contains("当前评价课程为")', autoGrade);
}

function autoGrade() {
    $(".input-xspj-1 label input").prop("checked",true);
    let pjContent = $('#jsxm').html() + "老师辛苦了！";
    $("textarea.input-zgpj").text(pjContent);
    $("#btn_xspj_tj").click();
    $('#btn_ok').click();
    waitForRefresh();
}

gotoNext();

For the semi-auto version, copy the code snippet below:

var ungraded;
var numOfUngraded = $('tr:contains("未评")').length;

function waitForAppearance(element, callBack) {
    if($(".alert-modal").length) {
        return;
    }
    window.setTimeout( function() {
        if($(element).length){
            if(element == 'div.col-sm-8:contains("当前评价课程为")') {
                autoGrade();
            } else {
                waitForDisappearance();
            }
        }else{
            waitForAppearance(element, callBack);
        }
    }, 200);
}

function waitForDisappearance() {
    window.setTimeout( function() {
        if($(".success-modal").length == 0) {
            waitForRefresh();
        } else {
            waitForDisappearance();
        }
    }, 200);
}

function waitForRefresh() {
    window.setTimeout( function() {
        var num = $('tr:contains("未评")').length;
        if(num != numOfUngraded) {
            numOfUngraded = num;
            gotoNext();
        } else {
            waitForRefresh();
        }
    }, 5000);
}

function gotoNext() {
    ungraded = $('tr:contains("未评"):first');
    if(ungraded.length == 0) return;

    $("#tempGrid").setSelection(ungraded.attr("id"));

    waitForAppearance('div.col-sm-8:contains("当前评价课程为")', autoGrade);
}

function autoGrade() {
    $(".input-xspj-1 label input").prop("checked",true);
    let courseInfo = $('div.col-sm-8:contains("当前评价课程为")').text();
    courseInfo = courseInfo.substring(courseInfo.indexOf("当前"), courseInfo.indexOf(";"))
    $("textarea.input-zgpj").text(prompt(courseInfo + "，主观题填什么？"));
    $("#btn_xspj_tj").click();
    waitForAppearance(".success-modal", waitForDisappearance);
}

gotoNext();

Step 3

Return to Student Evaluation page, and open the console of your browser. If you do not now the keyboard shortcut, please right click the page, click Insepct or something of similar meaning in the pop-up menu. An embedded window will pop up in your browser. On the top menu bar, select Console.

Step 4

Paste the code in the input section and press Enter.

Step 5

The grading starts。Current, the user will not be informed of the end of evaluation。If you want to terminate the process, simply refresh the page.
