How to Use the Js time function getYear ()

The getYear () function is not recommended long ago, because it is incorrectly displayed in Firefox, And the getFullYear () function is recommended.
Firefox does not support the innerText attribute. You need to change it to textContent to receive the message.
Then, attach the code
Copy codeThe Code is as follows:
Var s, Sys ={}, ua = window. navigator. userAgent. toLowerCase ();
(S = ua. match (/msie ([\ d.] + )/))? Sys. ie = s [1]:
(S = ua. match (/firefox \/([\ d.] + )/))? Sys. firefox = s [1]:
(S = ua. match (/chrome \/([\ d.] + )/))? Sys. chrome = s [1]:
(S = ua. match (/opera. ([\ d.] + )/))? Sys. opera = s [1]:
(S = ua. match (/version \/([\ d.] +). * safari /))? Sys. safari = s [1]: 0;
// Test the browser version.
// If (Sys. ie) {document. write ('ie: '+ Sys. IE );}
// If (Sys. firefox) {document. write ('Firefox: '+ Sys. Firefox );}
// If (Sys. chrome) {document. write ('chrome: '+ Sys. Chrome );}
// If (Sys. opera) {document. write ('Opera: '+ Sys. Opera );}
// If (Sys. safari) {document. write ('safari: '+ Sys. Safari );}
Var today = new Date ();
Var day, date;
If (today. getDay () = 0) {day = "Sunday ";}
If (today. getDay () = 1) {day = "Monday ";}
If (today. getDay () = 2) {day = "Tuesday ";}
If (today. getDay () = 3) {day = "Wednesday ";}
If (today. getDay () = 4) {day = "Thursday ";}
If (today. getDay () = 5) {day = "Friday ";}
If (today. getDay () = 6) {day = "Saturday ";}
Date = "today is:" + (today. getFullYear () + "year" + (today. getMonth () + 1) + "month" + today. getDate () + "day" + day + "";
If (Sys. firefox)
{
Document. getElementById ('time _ id'). textContent = date;
