在作业中插入额外文本的 Moodle 作业功能

Question

许多大学都有蓝卡计划，允许有特殊学习困难 (SpLD) 的学生用蓝卡标记他们的作业，因此导师会给予适当的考虑。

我们需要一种方法让学生更容易地用蓝卡标记他们的工作，我想出了以下脚本，它进入 Moodle 站点管理中的附加 HTML 部分，并与 Moodle 分配功能一起使用（请参阅前面的 post 以获得）。

首先，学生单击添加蓝卡的按钮，在提交评论字段中插入带有 "Blue Card" 字样的评论。提交表单时，JavaScript在评分table中查找评论，并在状态栏中添加标志，提醒导师审阅评论。然后导师可以显示评论并看到单词 "Blue Card"（这是阅读障碍评分指南的 link）。

Answer 1

/* MOODLE ASSIGNMENT BLUE CARD */

var MoodleAssignBlueCardButton =  '<input type="button" id="mabluecard" value="Flag with Blue Card" class="bluecard"/> <a href="http://www.brookes.ac.uk/students/wellbeing/dyslexia-spld/blue-marking-cards/"  target="_blank" title="What is the Blue Card scheme?">What\'s this?</a><br/>';

if (!document.getElementsByClassName('submissionstatustable')[0]) {
   /* do nothing */
} else {
    var assignTable = document.getElementsByClassName('submissionstatustable')[0];
    assignTable.insertAdjacentHTML('beforebegin', MoodleAssignBlueCardButton);
}

/* EVENT LISTENER FOR MOODLE ASSIGNMENT BLUE CARD BUTTON */
if (!document.getElementById('mabluecard')) {
   /* do nothing */
} else {
    document.getElementById("mabluecard").addEventListener('click', function () {  
        var commentbox = document.getElementsByClassName('comment-area')[0];
        var textarea = commentbox.getElementsByTagName('textarea')[0];
        if (!textarea.value) {
            textarea.value = ('<a href="http://www.brookes.ac.uk/students/wellbeing/dyslexia-spld/blue-marking-cards/" target="_blank" style="background-color: #99ccff">Blue Card</a>'); 
         } else if  (textarea.value == 'Add a comment...') {
               textarea.value = ('<a href="http://www.brookes.ac.uk/students/wellbeing/dyslexia-spld/blue-marking-cards/" target="_blank" style="background-color: #99ccff">Blue Card</a>'); 
       } else {
            textarea.value = ('<a href="http://www.brookes.ac.uk/students/wellbeing/dyslexia-spld/blue-marking-cards/" target="_blank" style="background-color: #99ccff">Blue Card</a>: ' + textarea.value);
         }
    /* save the comment */
    document.getElementsByClassName("comment-link")[0].click();
    var saveLink = document.getElementsByClassName("fd")[0].getElementsByTagName("a")[0];
     saveLink.click();
    });
}

/* flag the Blue Card submission in the Grading Table */
if (!document.getElementsByClassName('gradingtable')[0]) {
   /* do nothing */ 
} else {
    var table = document.getElementsByClassName('gradingtable')[0];
     var tbody = table.getElementsByTagName('tbody')[0];

     var comments = tbody.getElementsByClassName('c10');
         for (var i=0, len=comments.length; i<len; i++){
             if (comments[i].innerHTML.includes('Comments')){
              thisRow = comments[i].parentNode;
            thisRow.style.backgroundColor = '#ffffcc';
            statusCell = thisRow.getElementsByClassName("c5")[0];
             statusCell.innerHTML += ' <div style="background-color: #99bbff">Student has added comments, please review</div>';
            }
        }
    }

更新：为了让它在 Internet Explorer 11 中工作，我必须进行以下调整：

/* flag the Blue Card submission in the Grading Table */
if (!document.getElementsByClassName('gradingtable')[0]) {
   /* do nothing */ 
} else {
     var table = document.getElementsByClassName('gradingtable')[0];
     var tbody = table.getElementsByTagName('tbody')[0];
     var comments = tbody.getElementsByClassName('c10');
         for (var i=0, len=comments.length; i<len; i++){
             if (comments[i].innerText.search('Comments') > -1){
            thisRow = comments[i].parentNode; 
           alert('thisRow ' + thisRow);
            thisRow.style.backgroundColor = '#ffffcc';
            nameLink = thisRow.getElementsByTagName("a")[1]; 
            nameLink.insertAdjacentHTML('afterend', ' <div style="background-color: #99bbff">Student has added comments, please review</div>');
             }
        }
    }

还需要以下 CSS 才能使 "Add Blue Card" 按钮变为蓝色：

.bluecard {
  background-color: rgba(0, 0, 255, 1) !important;
  color: #fff;
  padding: 6px;
  border-radius: 6px;
}

这是因为 includes() method and the innerHTML() method 在 IE 中不起作用。
