  • 轻量级的日期插件--datebox

    jquery的日期插件有好几款,H5中的input也可以自带日期选择。但为什么要再写一个,有两个理由,一个是引用的文件太大,而有时候只需要很简单的功能,二个是想加一些自定义的效果不好改。

    我写的这个功能比较简单,可以换月,有预约效果,可以设定预约日期范围,压缩后1.4kb,先上个图,再慢慢解释:

    js代码:

    复制代码
    $.fn.datebox = function (options) {
        var config = {
            $valueEle: $("#outputTime"),
            $prev: $(".datetitle #up"),
            $next: $(".datetitle #down"),
            minDate:null,
            maxDate:null,
        }
        config = $.extend(config, options);
        Date.prototype.format = function (format) {
            var o = {
                "M+": this.getMonth() + 1, //month
                "d+": this.getDate(), //day
                "h+": this.getHours(), //hour
                "m+": this.getMinutes(), //minute
                "s+": this.getSeconds(), //second
                "q+": Math.floor((this.getMonth() + 3) / 3), //quarter
                "S": this.getMilliseconds() //millisecond
            }
            if (/(y+)/.test(format))
                format = format.replace(RegExp.$1,
                    (this.getFullYear() + "").substr(4 - RegExp.$1.length));
            for (var k in o)
                if (new RegExp("(" + k + ")").test(format))
                    format = format.replace(RegExp.$1,
                        RegExp.$1.length == 1 ? o[k] :
                            ("00" + o[k]).substr(("" + o[k]).length));
            return format;
        };

    公布了isLeap,next,prev,getdate,seleted 五个方法(看名字就不需要解释了吧)。默认今天是最小的预约时间。

    可以这样设定最大的可预约时间:

     var date = $(".datebox").datebox({maxDate:"2016-12-20"});

    换月的时候日期会自动切换到可预约的日期。

    demo下载:http://files.cnblogs.com/files/stoneniqiu/datebox.zip   样式不喜欢的可以自己去改动。功能上要增增渐渐也很方便。
