基于JavaScript实现每日签到打卡轨迹功能

1. 核心文件 calendar.js 

var calUtil = { //当前日历显示的年份 showYear:2018, //当前日历显示的月份 showMonth:1, //当前日历显示的天数 showDays:1, eventName:"load", //初始化日历 init:function(signList){ calUtil.setMonthAndDay(); calUtil.draw(signList); }, draw:function(signList){ //绑定日历 var str = calUtil.drawCal(calUtil.showYear,calUtil.showMonth,signList); $("#calendar").html(str); //绑定日历表头 var calendarName=calUtil.showYear+"年"+calUtil.showMonth+"月"; $(".calendar_month_span").html(calendarName); }, //获取当前选择的年月 setMonthAndDay:function(){ switch(calUtil.eventName) { case "load": var current = new Date(); calUtil.showYear=current.getFullYear(); calUtil.showMonth=current.getMonth() + 1; break; case "prev": var nowMonth=$(".calendar_month_span").html().split("年")[1].split("月")[0]; calUtil.showMonth=parseInt(nowMonth)-1; if(calUtil.showMonth==0) { calUtil.showMonth=12; calUtil.showYear-=1; } break; case "next": var nowMonth=$(".calendar_month_span").html().split("年")[1].split("月")[0]; calUtil.showMonth=parseInt(nowMonth)+1; if(calUtil.showMonth==13) { calUtil.showMonth=1; calUtil.showYear+=1; } break; } }, getDaysInmonth : function(iMonth, iYear){ var dPrevDate = new Date(iYear, iMonth, 0); return dPrevDate.getDate(); }, bulidCal : function(iYear, iMonth) { var aMonth = new Array(); aMonth[0] = new Array(7); aMonth[1] = new Array(7); aMonth[2] = new Array(7); aMonth[3] = new Array(7); aMonth[4] = new Array(7); aMonth[5] = new Array(7); aMonth[6] = new Array(7); var dCalDate = new Date(iYear, iMonth - 1, 1); var iDayOfFirst = dCalDate.getDay(); var iDaysInMonth = calUtil.getDaysInmonth(iMonth, iYear); var iVarDate = 1; var d, w; aMonth[0][0] = "日"; aMonth[0][1] = "一"; aMonth[0][2] = "二"; aMonth[0][3] = "三"; aMonth[0][4] = "四"; aMonth[0][5] = "五"; aMonth[0][6] = "六"; for (d = iDayOfFirst; d < 7; d++) { aMonth[1][d] = iVarDate; iVarDate++; } for (w = 2; w < 7; w++) { for (d = 0; d < 7; d++) { if (iVarDate <= iDaysInMonth) { aMonth[w][d] = iVarDate; iVarDate++; } } } return aMonth; }, ifHasSigned : function(signList,day){ var signed = false; $.each(signList,function(index,item){ if(item.signDay == day) { signed = true; return false; } }); return signed ; }, drawCal : function(iYear, iMonth ,signList) { var myMonth = calUtil.bulidCal(iYear, iMonth); var htmls = new Array(); htmls.push("<div>"); htmls.push("<div>"); htmls.push("<div></div>"); htmls.push("</div>"); htmls.push("<div>"); htmls.push("<table>"); var d, w; for (w = 1; w < 7; w++) { htmls.push("<tr>"); for (d = 0; d < 7; d++) { var ifHasSigned = calUtil.ifHasSigned(signList,myMonth[w][d]); console.log(ifHasSigned); if(ifHasSigned){ htmls.push("<td>" + (!isNaN(myMonth[w][d]) ? myMonth[w][d] : " ") + "</td>"); } else { htmls.push("<td>" + (!isNaN(myMonth[w][d]) ? myMonth[w][d] : " ") + "</td>"); } } htmls.push("</tr>"); } htmls.push("</table>"); htmls.push("</div>"); htmls.push("</div>"); return htmls.join(''); } };

2. 页面Js引入

<script src="https://www.jb51.net/jquery.min.js"></script> <script src="https://www.jb51.net/~calendar.js"></script>

3.0 后台拉取会员已经签到的打卡轨迹，填充到表格中去。 

var signList=[{"signDay":"23"},{"signDay":"24"},{"signDay":"25"},{"signDay":"26"},{"signDay":"30"}]; //填充到日历表格中 calUtil.init(signList);
