JS获取到本周的日期

<script type="text/javascript"> function makeDate() { var date = new Date(); var month = date.getMonth(); var week = date.getDay(); var month = month + 1; var day = date.getDate();
　　　　　　// week：周几，day：几号 var weekArr = [{week:‘‘,day:‘‘},{week:‘‘,day:‘‘},{week:‘‘,day:‘‘},{week:‘‘,day:‘‘},{week:‘‘,day:‘‘},{week:‘‘,day:‘‘},{week:‘‘,day:‘‘}]; var leftNum = week-1; // 本周内今天的前几天的数量 var rightNum = 7-week; // 本周内今天的后几天的数量
　　　　　　// 本周内今天的前几天 for(var i=0; i<leftNum; i++){ weekArr[i].week = week-(week-i)+1; if(i==0){ weekArr[i].day = day-week; }else{ weekArr[i].day = day-(week-i)+1; } }
　　　　　　// 本周内今天的后几天 for(var i=0; i<rightNum; i++){ weekArr[i+week].week = week+i+1; weekArr[i+week].day = day+i+1; }
　　　　　　// 今天 weekArr[week-1].week = week; weekArr[week-1].day = day; console.log(weekArr) } makeDate();</script>
