JS Built-in Object Processing _ print student transcripts simple to achieve _javascript skills

Task:

1. Get the current date through the built-in object of JS

var date=new date ();

var year=date.tostring (). Slice (11,15);
document.write (year.tostring () + "year");

var month=date.getmonth ();
month=month+1;
if (month<10) {

document.write ("0" +month+ "month");
} else{
document.write (month+ "Month"); 
}

var day=date.tostring (). Slice (8,10);
document.write (day+ "Day");

var weekday=["Day", "one", "two", "three", "four", "five", "six"];
var week=date.getday ();
document.write ("Week" +weekday[week]);

2. Better operation of the string in an array

var scorestr = "Xiao Ming: 87; Floret: 81; Xiao Hong: 97; Little day: 76; little Zhang: 74; small: 94; Xiao XI: 90; Xiao Wu: 76; Dicky: 64; Xiaoman:";
var scorearr=scorestr.split (";");

3. Rub the score out of the array, sum the whole and output

function Getnum (str) {
var str1=str.replace (/[*0-9]/ig, "");
Return Str.replace (STR1, "");
}

 

var num=0, Len=scorearr.length;
for (Var i=0;i<len;i++) {
var num1=getnum (Scorearr[i]);
Num+=number (NUM1);
}
Num=parseint (Num/len);
document.write ("--the average class is divided into:" +num);

Here's my chart of effects:
