JavaScript实现移动端滑动选择日期功能

 $(page).on('touchmove','#touchMoveTime',function (event) { touchMove(event); }); scrollBarInit(); //初始化 function scrollBarInit() { var defaultValue = 3,maxValue = 30; var myDate = new Date(); var year = myDate.getFullYear(); var month = myDate.getMonth() + 1; //获取当前月份(0-11,0代表1月) var date = myDate.getDate(); var day = new Date(year,month,0); var daycount = day.getDate(); //获取本月天数： if((date + defaultValue) > daycount){ if(month == 12){ month = 1; year = year + 1; }else{ month = month + 1; } date = (date + defaultValue) - daycount; }else{ date = date + defaultValue; } if(month <10){ month = "0"+month; } if(date <10){ date = "0"+date; } $("#endTime").attr('value',year+'-'+month+'-'+date); var currentX = $("#touchMoveTime").width() * (0 / maxValue); $('#scroll_Track').css({width:currentX+"px"}); $('#scroll_Thumb').css({transform:'translate(' + currentX + 'px, 0)'}); }; function touchMove(event) { event.preventDefault(); if (!$('#scroll_Thumb') || !event.touches.length) return; var defaultValue = 3,maxValue = 30; var myDate = new Date(); var year = myDate.getFullYear(); var month = myDate.getMonth() + 1; //获取当前月份(0-11,0代表1月) var date = myDate.getDate(); var tran_currentX = ''; var startOffset = parseInt($('#touchMoveTime').offset().left); var endOffset = parseInt($('#touchRight').offset().left); var _limit = endOffset - startOffset; var touchMoveTimeOffsetLeft = $('#scroll_Track').offset().left; var touch = event.touches[0]; var endX = touch.pageX; var currentX = endX - touchMoveTimeOffsetLeft; var Timevalue = Math.round(maxValue * (currentX / $("#touchMoveTime").width())); //当前刻度值 if(Timevalue  maxValue){ Timevalue = maxValue; } if(currentX <_limit && currentx> 15){ $('#days').text(Timevalue); $('#scroll_Track').css({width:currentX+"px"}); if(currentX <20){ tran_currentX = 0 }else{ tran_currentX = currentX - 20; } $('#scroll_Thumb').css({transform:'translate(' + tran_currentX + 'px, 0)'}); var day = new Date(year,month,0); var daycount = day.getDate(); //获取本月天数 if((date + Timevalue) > daycount){ if(month == 12){ month = 1; year = year + 1; }else{ month = month + 1; } date = (date + Timevalue) - daycount; }else{ date = date + Timevalue; } if(month <10){ month = "0"+month; } if(date <10){ date = "0"+date; } $('#endTime').attr('value',year+'-'+month+'-'+date); } }
