JS中时间格式化方法

function resetQuery() {
    var dt = new Date();
    var endTimeStr = formatDate(dt) ;
    $("#endTimeStr").val(endTimeStr);
    dt.setMonth( dt.getMonth()-2);
    var startTimeStr = formatDate(dt) ;
    $("#startTimeStr").val(startTimeStr);
    /* console.log( dt.toLocaleString() );
    alert(dt.toLocaleString()); */
}

function formatDate(date) {
    var myyear = date.getFullYear();
    var mymonth = date.getMonth() + 1;
    var myweekday = date.getDate();
 
    if (mymonth < 10) {
        mymonth = "0" + mymonth;
    }
    if (myweekday < 10) {
        myweekday = "0" + myweekday;
    }
    return (myyear + "" + mymonth);
}
