1.日历组件
1.分析功能:日历基本功能,点击事件改变日期,样式的改变
1.结构分析:html
1.分为上下两个部分
2.上面分为左按钮,中间内容展示,右按钮
下面分为周几展示和日期展示
3.基本结构页面html书写
v-for="item in ['日','一','二','三','四','五','六']"
:key= item
>{{ item }}
class="every-day"
v-for="item in 42"
:key="item"
>{{ item }}

border:20px solid ;
border-color: transparent rgb(35, 137, 206) transparent transparent;
}

display: inline-block;
line-height: 40px;
text-align: center;
width: 310px;

}

color: #fff;
font-size: 14px;
text-align: center;
line-height: 20px;
}

margin: 0;
padding: 0;
display: inline-block;
height: 20px;
width: 60px;
}
.every-day{
display: inline-block;

}
.other-day{

}
.active-day{
/* padding: 2px */
/* border-sizing:content-box; */
border: 2px solid rgb(35, 137, 206);
}
4.一些事件以及逻辑
1.使得当前的日期为今天的日期
data(){
return{
year:null,
month:null,
day:null
}
},
created(){
this.getInitDate();
},
methods:{
getInitDate(){
const date = new Date();
this.year = date.getFullYear();
this.month = date.getUTCMonth() + 1;
this.day = date.getDate();
}
}
2.设置该月日期起始值(找到一号是在哪里)
beginDay(){
return new Date(this.year, this.mounth - 1, 1).getDay();
}
3.当月天数字体正常显示
v-if="item - beginDay >= 0 && item - beginDay <= curDays"
>{{ item - beginDay }}
4.当月天数之前的部分变灰,外加正常显示日期
注意几个数学问题:
1.当前月天数日期
2.上月剩余天数
3.此月显示的下月天数
v-if="item - beginDay > 0 && item - beginDay <= curDays"
>{{ item - beginDay }}
class="other-day"
v-else-if="item - beginDay <= 0"
>{{ item - beginDay + prevDays }}
class="other-day"
v-else>{{ item - beginDay -curDays }}
5.能知道当前日期,能点击其他日期,并且会有相应的变化
知道当前日期:
this.curDate = `${this.year}-${this.month}-${this.day}`
判断今天是不是当前日期,并且给一个样式:
'now-day':`${year}-${month}-${item - beginDays}` == curDate
当点击当月有的日期的时候会根据你的点击显示的日期发生变化
判断是点击的那一天:
'active-day':`${year}-${month}-${item - beginDay}` === `${year}-${month}-${day}`
点击这一天,绑定点击事件
@click="handleClickDay(item - beginDay)"
handleClickDay(day){
this.day = day
}
6.前后两个按钮的功能
handlePrev(){
if(this.month == 1){
this.month = 12
this.year--
}else{
this.month--
}
},
handleNext(){
if(this.month == 12){
this.month = 1
this.year++
}else{
this.month++
}
}
7.判断点击的是否为当月的最后一天
computedDay(){
const allDay = new Date(this.year, this.month, 0).getDate();
if(this.day > allDay){
this.day = allDay;
}
}
将这个函数分别在handlePrev(),handleNext()里面执行-------注意是this.computedDay();
完成
