先上一個(gè)效果圖:
時(shí)間改為5月份的效果圖:
直接上代碼:

wxss:
.modalBox{ width: 100%; font-size: 32rpx; } .box{ margin: 0 auto; width: 630rpx; } .calendarTitle{ /* margin: 0 auto; width: 630rpx; */ width: 100%; height: 80rpx; line-height: 80rpx; text-align: center; border-bottom: 1rpx solid #ddd; } .calendarBox{ /* width: 630rpx; */ width:100%; margin: 0 auto; border:1rpx solid #ddd; } .week{ display: inline-block; width:90rpx; height: 80rpx; text-align: center; line-height: 80rpx; border-bottom: 1rpx solid #ddd; } .dateBtn{ width:100%; height: 80rpx; display: flex; justify-content: space-between; margin-top: 20rpx; } .dateBtn>button{ width: 45%; height: 100%; display:flex; justify-content: center; align-items: center; margin: 0; font-size: 36rpx; } /* 模態(tài)框 */ .modal-mask { width: 100%; height: 100%; position: fixed; top: 0; left: 0; background: #000; opacity: 0.5; overflow: hidden; z-index: 9000; } .modal-dialog { width: 85%; padding: 100rpx 30rpx 30rpx 30rpx; overflow: hidden; position: fixed; top: 20%; left: 0; right: 0; margin: 0 auto; z-index: 9999; background: rgba(255, 255, 255, 1); border-radius: 5rpx; }
js:
Page({ /** * 頁(yè)面的初始數(shù)據(jù) */ data: { showModal:true, weekLength:7, week:["日","一","二","三","四","五","六"], dayList:[], weekNum:0, tapThis:0, thisMonth:0, thisYear:0, dayIndex:0, chooseDate:"", }, getWeek(year,month,day){ var that = this; var d = new Date(); d.setFullYear(year); d.setMonth(month-1); d.setDate(1); var n = d.getDay(); var arr =[]; var Index=0; var dayN=1; for(var i = 0; i<day; i++){ arr.push(dayN++); } var now = new Date(); var nowYear = now.getFullYear(); var nowMonth = now.getMonth()+1; var nowDay = now.getDate(); var val = 1; if(year==nowYear){ if(month==nowMonth){ Index=arr.indexOf(nowDay); console.log(Index); val = nowDay; } } that.setData({ weekNum:n, dayList:arr, dayIndex:Index, tapThis:Index, thisMonth:month, thisYear:year, chooseDate:year+"-"+month+"-"+val, }) }, chooseDate(e){ var that = this; var n = e.currentTarget.dataset.index; var val = e.currentTarget.dataset.value; console.log(n); if(n>=that.data.dayIndex){ that.setData({ tapThis:n, chooseDate:that.data.thisYear+"-"+that.data.thisMonth+"-"+val, showModal:true, }) } }, /** * 彈出框蒙層截?cái)鄑ouchmove事件 */ preventTouchMove: function () { }, /** * 隱藏模態(tài)對(duì)話框 */ hideModal() { var that = this; that.setData({ showModal: true, }) }, showModalBtn(){ var that = this; that.setData({ showModal:false }) }, /** * 生命周期函數(shù)--監(jiān)聽(tīng)頁(yè)面加載 */ onLoad: function (e) { var that = this; that.getWeek("2018","04","31"); //使用方法: 在此函數(shù)內(nèi)傳入年、月、日(此月的天數(shù))即可。 } })
代碼設(shè)計(jì)思路:
1、此代碼是符合我們公司實(shí)際情況定制的,選擇哪個(gè)月份,需要傳遞哪個(gè)月份的參數(shù),比如我要2018-04的日歷選擇器,那么我需要在 getWeek() 中傳遞年,月,日(此月的總天數(shù))作為參數(shù),代碼會(huì)自動(dòng)計(jì)算出當(dāng)月的一號(hào)是星期幾并且排版好!
如果不知道此月的天數(shù) ,這里還提供如下代碼方便各位碼友計(jì)算出各個(gè)月份的天數(shù)
getDayNum(year,month){ //傳入?yún)?shù)年份 和 要計(jì)算的月份, 可以為字符串,也可以為數(shù)字。 var that = this; var d = new Date(); d.setFullYear(year); d.setMonth(month); d.setDate(0); console.log(d.getDate()); //d.getDate() 即為此月的總天數(shù)! },
2、具體思路就是:根據(jù)傳遞的參數(shù)計(jì)算出當(dāng)月的第一天為星期幾,然后從星期幾開(kāi)始排列,通過(guò)循環(huán){{總天數(shù)}}次,讓日期循環(huán)出來(lái)。然后再獲取當(dāng)前日期,判斷日歷彈窗與當(dāng)前月份是否吻合,如果吻合,就要將在當(dāng)前日期之前的日期都設(shè)置為不可點(diǎn)擊狀態(tài)。然后就是點(diǎn)擊獲取值,整個(gè)日歷流程完畢。
