vue项目实现会议预约（包含某天的某个时间段和某月的某几天）

一、一天的时间段预约

会议预约有以下操作：
1.点击预约按钮，弹窗最近一周的预约时间点（半小时一个点），预约时间为5:00到24:00;
2.超过当前时间的时间点不允许再预约，已经预约的时间不允许再预约，预约的时间段内有已经预约的时间点不允许预约；
3.预约时间为时间段，所以最少包含两个时间点，选中两个时间点时，两个时间点被选中，若两个时间点内有其他时间点，其他时间点也要被选中；
4.已经选中的时间点再次点击时，取消选中，

css部分

.top_style,.top_active{border:1px solid #AAA;padding:3px 20px;text-align:center;
}
.top_active{border-color:#02A7F0;color: #02A7F0;
}
.button_style{text-align:center;float:left;width: 80px;
}

js部分

1.点击预约时，记录下会议id及name，位置id及name，并把会议id，当前时间（0点~24点）传过去，后台需要根据时间返回时间点数组

	//预约addAppoint(val){this.isAppoint=true;this.appointAreaId=val.appointAreaId;this.appointAreaName=val.appointAreaName;this.positionId=val.positionId;this.positionName=val.positionName;this.getAppoint();let formData={appointAreaId:val.appointAreaId,startTime:this.getYMD(new Date())+' '+'00:00:00',endTime:this.getYMD(new Date())+' '+'23:59:59'}this.getAppointed(formData);},//每次打开预约弹窗时，默认选中当天getAppoint(){let arr = []for (let i = 0; i < 7; i++) {arr.push(this.dealTime(i))}arr[0].is_active=1;this.week=arr;this.dateNow=this.week[0].full;},

2.获取时间数组

//获取时间数组getAppointed(formData){appointTime(formData).then(res=>{this.timeArr=res.data.data;if(res.data.code==200){this.timeArr=res.data.data;}})},

时间数组格式为：时间点+状态；未选中状态为0，已经预约过的状态为1，不可预约(过期时间)的状态为2，当前预约(即点击时选中)的状态为3（这个状态为点击时判断，不要接口返回）

3.处理未来七天的函数

// 处理未来七天的函数dealTime(num){let time = new Date() // 获取当前时间日期let date = new Date(time.setDate(time.getDate() + num)).getDate() //这里先获取日期，在按需求设置日期，最后获取需要的let newDate=(date.toString()).padStart(2,"0");let month = time.getMonth() + 1 // 获取月份let newMonth=(month.toString()).padStart(2,"0");let day = time.getDay() //  获取星期let year=time.getFullYear();let full=year+'-'+month+'-'+date;switch (day) { //  格式化case 0:day = "星期日"breakcase 1:day = "星期一"breakcase 2:day = "星期二"breakcase 3:day = "星期三"breakcase 4:day = "星期四"breakcase 5:day = "星期五"breakcase 6:day = "星期六"break}let obj = {date: newDate,day: day,is_active: 0,month: newMonth,year:year,full:full,}return obj // 返回对象},

4.点击切换星期状态

//点击切换星期状态changWeek(val,index){for(let i=0;i<this.week.length;i++){this.week[i].is_active=0;}//星期切换时，其他星期状态重置为0，即未选中，当前星期状态为1，即选中this.week[index].is_active=1;let formData={appointAreaId:this.appointAreaId,startTime:val.full+' '+'00:00:00',endTime:val.full+' '+'23:59:59'};this.dateNow=val.full;//dateNow为当前选中时的日期（年月日）this.getAppointed(formData)},

5.选中时间点时，判断状态及改变状态

//选中时间点时，判断状态及改变状态
//appointTimeArr 保存点击的按钮的数组，即当前选中数组changTime(val,index){//当前选中数组的长度小于2时，即点击了1次、2次if(this.appointTimeArr.length<2){this.timeArr[index].status=3;点击按钮的状态设为3，即当前选中this.appointTimeArr.push(index);//当前选中数组的长度为2，即点击了2次if(this.appointTimeArr.length==2){//选中数组的俩个下标一样时，即同一个时间点点击了两次，即取消选中，则把状态都重置为0，并且清空选中数组if(this.appointTimeArr[0]==this.appointTimeArr[1]){this.timeArr[this.appointTimeArr[0]].status=0;this.appointTimeArr=[];}else{//选中数组的两个下下标不一样时，对数组进行排序，顺序排序，如若是[3,2]则改为[2,3]，开始时间点和结束时间点this.appointTimeArr=this.appointTimeArr.sort(function(a,b){return a-b});//求出开始时间和结束时间之间选中的时间点个数，let len=this.appointTimeArr[1]-this.appointTimeArr[0];//根据个数，把选中时间段内的时间的状态都改为3，即当前选中for(let i=0;i<len;i++){//将下选中数组内容的下标与时间数组的下标状态进行比对，若是有状态等于1的，即已有预约，则做出提示，并且把开始时间点和结束时间点重置为空，循环终止if(this.timeArr[this.appointTimeArr[0]+i].status==1){this.$message.warning("已预约过的时间不允许预约！")this.timeStart='';this.timeEnd='';break}else{将最终获取到的选中数组下标与时间数组进行比对，获取开始时间点和结束时间点，并且状态改为3，即当前选中this.timeArr[this.appointTimeArr[0]+i].status=3;this.timeStart=this.timeArr[this.appointTimeArr[0]].time;this.timeEnd=this.timeArr[this.appointTimeArr[1]].time;}}}}}else if(this.appointTimeArr.length=3){//当前选中数组的长度等于3时，即点击了3次，则把前两个状态改为0，即未选中，把第三次点击时的状态设为3，即当前选中for(let i=0;i<this.timeArr.length;i++){if(this.timeArr[i].status===3){this.timeArr[i].status=0;}}this.appointTimeArr=[];this.appointTimeArr.push(index);this.timeArr[index].status=3;}},

6.保存

saveAppoint(){//保存时，开始时间点和结束时间点必须存在，即选中数组的长度为2，否则做出提示，并且将选中的下标对赢得时间点状态重置为0，即未选中if(this.timeStart!=''&&this.timeEnd!=''){this.appointForm.appointAreaId=this.appointAreaId;this.appointForm.appointAreaName=this.appointAreaName;this.appointForm.positionId=this.positionId;this.appointForm.positionName=this.positionName;this.appointForm.remark=this.remark;//对开始时间和结束时间进行拼接，即当前选中星期对应的日期+当前选中时间点this.appointForm.startTime=this.dateNow+' '+this.timeStart;this.appointForm.endTime=this.dateNow+' '+this.timeEnd;appoint(this.appointForm).then(res=>{if(res.data.code==200){this.$message.success(res.data.message)this.remark='';this.isAppoint=false;this.isMeeting=falsethis.getList();}else{this.$message.error(res.data.message)}})}else{this.$message.error("请选择预约时间")for(let i=0;i<this.timeArr.length;i++){if(this.timeArr[i].status==2){this.timeArr[i].status=0}}}},

7.弹窗关闭

closeAppoint(){this.isAppoint=false//弹窗关闭时，星期重置，默认选中星期数组的第一个，即当前日期对应的星期；重置备注；重置当前星期对应的时间数组中的状态为3的时间点状态为0，即未未选中for(let i=0;i<this.week.length;i++){this.week[i].is_active=0;}this.week[0].is_active=1;this.remark='';for(let i=0;i<this.timeArr.length;i++){if(this.timeArr[i].status==3){this.timeArr[i].status=0;}}},

二、一月的天数预约（最少一天）

1.时间数组同样由后端返回，把每月的第一天和最后一天传给后端，后端接口返回日期数组，
格式也是time+status，0代表未选中，1代表已有预约，2代表不可预约，3代表当前选中
2.与时间点预约不同的是，天数预约可以选择一个时间点，即某个月的某一天，其他的逻辑基本都差不多了，剩下的就是一些代码的不同了
3.天数预约比较有意思的就是会用到日历！没错就是日历，一开始是想着使用一些什么日历插件的，但是考虑到日历插件能满足我目前需求的可能性不大，所以只好想着给他画出来！哈哈，去百度了亿篇博客，然后自己再汇总+修改，so，手绘的日历出来了，切换月份啊，显示数据啊都么得问题的，嘿嘿，针不戳针不戳~
