Js 处理将时间转换 “年-月-日”

//时间转换
function ChangeDateFormat(val) {
    if (val != null) {
        var date = new Date(parseInt(val.replace("/Date(", "").replace(")/", ""), 10));
        //月份为0-11，所以+1，月份小于10时补个0
        var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
        var currentDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();
        return date.getFullYear() + "-" + month + "-" + currentDate;
    }
    return "";
}
