JS 獲取當前年份，月份

function doHandleDate() {
var myDate = new Date();
var tYear = myDate.getFullYear();
var tMonth = myDate.getMonth();

var m = tMonth + 1;
if (m.toString().length == 1) {
m = "0" + m;
}
return tYear +'-'+ m;
}
function doHandleYear(tYear) {
var myDate = new Date();
var tYear = myDate.getFullYear();

return tYear;
}
function doHandleMonth() {
var myDate = new Date();
var tMonth = myDate.getMonth();

var m = tMonth + 1;
if (m.toString().length == 1) {
m = "0" + m;
}
return m;
}

 //獲取完整的日期
 var date=new Date;
 var year=date.getFullYear(); 
 var month=date.getMonth()+1;
 month =(month<10 ? "0"+month:month); 
 var mydate = (year.toString()+month.toString());

注意，year.toString()+month.toString()不能寫成year+month。不然如果月份大於等於10，則月份為數字，會和年份相加，如201210，則會變為2022，需要加.toString()
