js 時(shí)間格式轉(zhuǎn)毫秒數(shù)

    var time= (new Date("2015/03/30 12:00:00")).getTime(); //得到毫秒數(shù)
    //下面格式的時(shí)間需要轉(zhuǎn)換：
    var time = '2015-03-30 12:00:00';
    time = time .replace(new RegExp("-","gm"),"/");
    var times = (new Date(time )).getTime(); //得到毫秒數(shù)
    //毫秒數(shù)轉(zhuǎn)化為時(shí)間
    var time = (new Date("2015/03/30 12:00:00")).getTime(); //得到毫秒數(shù)
    var newTime = new Date(time ); //就得到普通的時(shí)間了
