js 方法总结

  1.   格式化时间
 function format(str,fmt) {
        var usedDate = new Date(usedDay);
        var o = {
            "M+": usedDate.getMonth() + 1, //月份
            "d+": usedDate.getDate(), //日
            "h+": usedDate.getHours(), //小时
            "m+": usedDate.getMinutes(), //分
            "s+": usedDate.getSeconds(), //秒
            "q+": Math.floor((usedDate.getMonth() + 3) / 3), //季度
            "S": usedDate.getMilliseconds() //毫秒
        };
        if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (usedDate.getFullYear() + "").substr(4 - RegExp.$1.length));
        for (var k in o)
        if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
        return fmt;
    }
 
    var pattern = "yyyy-MM-dd";
    var usedDay = 1454112000000;
 
    usedDate=format(usedDay,pattern);

2.

var dialog = {
    title:'hi',
    show: function(){
        console.log(this.title);
    }
}
 
setTimeout(function(){
    dialog.show();
},5000)
