[Javascript] Entering Letter grades Automatically at UMEG

Entering letter grades automatically at UMEG

Putting letter grades in UMEG with 300 + clicks is cumbersome and prone to mistakes, especially for large sized classes.

An  alternative is to use Canvas(elms) to convert grades into UMEG. However, the functions provided by Canvas are rather restrictive (and slow). And we don’t want to create numerous alarms to be sent to students.

So we can try using the following script at UMEG to fill out the grades automatically.

var t = document.getElementsByTagName(“table”)[5];
var trs = t.getElementsByTagName(“tr”);

// input the grades you want to enter following the order in UMEG (name – ascending order)
var grades = [“A+”, “C”, “D”];

function to_num(letter) {
var i = null;
var j = 2;
if (letter[0] == “A”) {
i = 1
} else if (letter[0] == “B”) {
i = 2
} else if (letter[0] == “C”) {
i = 3
} else if (letter[0] == “D”) {
i = 4
}
if (letter.slice(-1) == “+”) {
j = 1
} else if (letter.slice(-1) == “+”) {
j = 3
}
return [i, j]
}

// change num as the number of students in your class
var num = 374
for (var i = 0; i<num; i++) {
var str_ = “grd” + i
var letter = to_num(grades[i])
var grade = trs[9*i + 1].getElementsByTagName(“td”)[letter[0]*4-2 + letter[1]].getElementsByTagName(“input”)[str_]
grade.checked = false;
grade.checked = true;
console.log(i)
}
