直接上代码。最简单的！第一段是HTML代码和简单的样式。

   
     
            
      
                 <                  <%=DateTime.Now.ToString("yyyy") %>年                <%=DateTime.Now.ToString("MM") %>月                  >             
            
      日            
      一            
      二            
      三            
      四            
      五            
      六            
      
            
      
    
     

第二段是JS代码

dateData(3);            function dateData(type){                    var date = new Date();                        date = new Date($('#year').html(), parseInt($('#month').html()),0);            var currentMonth = date.getMonth()+1;        //当前月                        var currentYear = date.getFullYear();                        if(type == 0){                if(currentMonth == 0){                    currentYear = currentYear - 1;                    currentMonth = 11;                }else{                    currentMonth = currentMonth -1;                }            }else if(type == 1){                if(currentMonth == 11){                    currentYear = currentYear + 1;                    currentMonth = 0;                }else{                    currentMonth = currentMonth +1;                }            }                        date = new Date(currentYear, currentMonth,0);                        var currentMaxDay = new Date(date.getFullYear(), date.getMonth() + 1,0).getDate();  //当前月 - 最大天                        var prevMaxDay = new Date(date.getFullYear(), date.getMonth(),0).getDate();         //上一月                        var nextMaxDay = new Date(date.getFullYear(), date.getMonth() + 2,0).getDate();     //下一月                        date.setDate(1);                        var currentWeek = date.getDay();    //当月1日是星期几？                        if(currentWeek == 0){                currentWeek = 7;            }                        date = new Date(currentYear, currentMonth,0);                        var html = "";                        //遍历上一月            for(var i = prevMaxDay - currentWeek + 1; i <= prevMaxDay;i++){                html+= "" + i + "";            }                        //遍历当前月            for(var j = 1;j <= currentMaxDay;j++ ){                html+= "" + j + "";            }                        //遍历下一月            for(var j = 1;j <= 42 - currentMaxDay - currentWeek ;j++ ){                html+= "" + j + "";            }            $('#content').html(html);            $('#year').html(date.getFullYear());            $('#month').html(date.getMonth() + 1);            var width = ($('#TaskCalendar').width() - 2) / 7;            $('#TaskCalendar label').css({width:width,float:"left"});        }        $(window).resize(function() {            var width = ($('#TaskCalendar').width() - 2) / 7;            $('#TaskCalendar label').css({width:width,float:"left"});        });

OK！就这么多！
