3、js代码实现

;
(function($) {
	var Checkin = function(ele, options) { // ele代表元素自己，options不知道是干啥的…
		this.ele = ele;
		this.opt = options;
		this.defaults = {
			width: 452,
			height: 'auto',
			background: '#f90',
			radius: 10,
			color: '#fff',
			padding: 10,
			dateArray: [1, 2, 4], // 假设已签到的天数+1，也就是签到天数的下标
		};
		//$.extend()为jQuery类添加类方法，可以理解为添加静态方法
		//其实就是一个空对象(obj)，包含进了defaults跟opt对象，
		this.obj = $.extend({}, this.defaults, this.opt);  
	}

	Checkin.prototype.init = function() {
		var _self = this.ele,
			html = '',
			myDate = new Date(),
			year = myDate.getFullYear(),
			month = myDate.getMonth(),
			day = myDate.getDate(),
			weekText = ['日', '一', '二', '三', '四', '五', '六'];

			padding: this.obj.padding
		}).append("<div class='title'><p>" + year + '年' + (month + 1) + '月' + day + '日' + "</p><a class=\'checkBtn\' href=\"javascript:;\">签到</a></div>");



		$("<ul class='week clearfix'></ul><ul class='calendarList clearfix'></ul>").appendTo(_self);

		var monthFirst = new Date(year, month, 1).getDay(); // 这个月的第一天是周几，11月是周三
		var d = new Date(year, (month + 1), 0);  //这个得到的是这个月的总天数：例：2017.11.30，2017.12.31
		var totalDay = d.getDate(); //获取当前月的天数，这个月的总天数

		for (var i = 0; i < totalDay; i++) { // 23→四，24→五
			$li.eq(i + monthFirst).html(i + 1);  // 每号对应的格子，即对应的星期
			$li.eq(i + monthFirst).addClass('data' + (i + 1))

			if (isArray(this.obj.dateArray)) {  // 判断是否是数组

			}
		}
		//$li.eq(monthFirst+day-1).css('background','#f7ca8e')
        // 给当天的日期添加able-qiandao类，表明今日可签到，也仅有今日可签到
		_self.find($(".data" + day)).addClass('able-qiandao');
	}  // init初始化结束

	var isChecked = false;
	Checkin.prototype.events = function() {
		var _self = this.ele;

				that.obj.dateArray.push($(this).index());
				console.log(that.obj.dateArray);

				modal(_self); //显示弹窗
				isChecked = true;
			}
		});
		var checkBtn = _self.find(".checkBtn");
		checkBtn.click(function(event) {

	}
	var modal = function(e) {

		e.parents().find('.checkBtn').text("已签到");
	}

	// $.fn = $.prototype，扩展checkin对象
	$.fn.Checkin = function(options) {

	};
})(jQuery);

// 插件调用
$(".checkin").Checkin();
// 元素居中显示，与插件无关，根本自己需要修改；
$(".checkin").css('marginTop',parseInt(($(window).innerHeight()-$(".checkin").outerHeight())/2)+'px');
