项目实战之基于JavaScript实现每日签到打卡轨迹功能

今天扣丁学堂HTML5培训老师给大家介绍一下关于js实现每日签到打卡轨迹功能的具体代码，希望对同学们学习HTML5开发有所帮助，下面我们一起来看一下吧。

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("
");
  htmls.push("
");
  htmls.push("
");
  htmls.push("
");
  htmls.push("
");
  htmls.push("");
  var d, w;
  for (w = 1; w <7; w++) {
  htmls.push("");
  for (d = 0; d <7; d++) {
   var ifHasSigned = calUtil.ifHasSigned(signList,myMonth[w][d]);
   console.log(ifHasSigned);
   if(ifHasSigned){
   htmls.push("");
   } else {
   htmls.push("");
   }
  }
  htmls.push("");
  }
  htmls.push("
" + (!isNaN(myMonth[w][d]) ? myMonth[w][d] : " ") + "
" + (!isNaN(myMonth[w][d]) ? myMonth[w][d] : " ") + "
");
  htmls.push("
");
  htmls.push("
");
  return htmls.join('');
 }
};

2、页面Js引入

3、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);
