JS动态生成年份和月份实例代码

function makeYear() {   var year = document.getElementById("year");   var my = new Date();   var endYear = my.getFullYear();// 获取当前年份   for (var i = 1900; i <= endYear; i++) {     year.options.add(new Option(i, i + '年'));   } } 

function makeMonth() {   var month = document.getElementById("month");   for (var i = 1; i <= 12; i++) {     /*      * if (i < 10) {         option.values='0'+i;         option.innerText='0'+i;      *  } else      *  {      *   option.values=i;      *   option.innerText=i;      * }      * month.appendChiled(option);      *      */     if (i < 10) {       month.options.add(new Option('0' + i, '0' + i));     } else {       month.options.add(new Option(i, i));     }   } }
