<! DOCTYPE html>//get the current date by using the JavaScript Date object and output.     varDay = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]; varDate =NewDate (); varindex =Date.getday (); varMyyear =date.getfullyear (); varMymon = Date.getmonth () +1; varMyDate =date.getdate (); //The result is a long-channeling string bad processing, find the rule after the split into the array better operation Oh    varScorestr = "Xiao Ming: 87; Floret: 81; Little red: 97; Small day: 76; Xiao Zhang: 74; little: 94; Xiao XI: 90; Xiao Wu: 76; Dicky: 64; Small ord: 76"; vararr = Scorestr.split (":");    Arr.shift (); //Extract the scores from the array, then sum them up and output them.     varARR1 = [];  for(vari = 0; i < arr.length; i++) {Arr1[i]=parseint (Arr[i]); }    varSum =0; functionAdd (arr) { for(vari=0;i<arr.length;i++) {sum+=Arr[i]; }        returnsum; }    varEnd = Math.Round (Add (arr1)/arr1.length); document.write (myyear+ "year" +mymon+ "month" +mydate+ "Day" +day[index]+ "--class score is" +end);</script></body>
