js 将日期转换成大写格式

function ConverToDate(date) {
    var chinese = ['0', '一', '二', '三', '四', '五', '六', '七', '八', '九'];
    var y = date.getFullYear().toString();
    var m = date.getMonth().toString();
    var d = date.getDate().toString();
    var result = "";
    for (var i = 0; i < y.length; i++) {
        result += chinese[y.charAt(i)];
    }
    result += "年";
    if (m.length == 2) {
        if (m.charAt(0) == "1") {
            result += ("十" + chinese[m.charAt(1)] + "月");
        }
    } else {
        result += (chinese[m.charAt(0)] + "月");
    } 
    if (d.length == 2) {
        result += (chinese[d.charAt(0)] + "十" + chinese[m.charAt(1)] + "日");
    } else {
        result += (chinese[d.charAt(0)] + "日");
    }
    return result;
