jQuery联动日历的实例解析

一、要实现的功能：

1.点击上面的箭头，切换至上一个月，或下一个月，并且是联动的。

2.只要不是现实中的当月，那么显示的日期，都是灰色底。

二、分析：

1.当我们点击切换日期的箭头时，要改变顶部蓝色的年份和日期。

2.当我们点击切换日期的箭头时，下面TD的日期也要和上面显示的月份对应起来。

3.用一个判断，是否现实中的当月，来控制TD的背景色，是否为灰色

//点击更新前一个月
 $(".pre").live("click",function(){
  nowTitleDateM--;
  if(nowTitleDateM == 11){
    nowLastM = nowTitleDateM-1
    nextTitleDateY--
    nextTitleDateM = nowTitleDateM+1
    nextLastM = 1
  }else if(nowTitleDateM == 0){
    nowTitleDateY--
    nowTitleDateM = 12;
    nowLastM = nowTitleDateM-1;
    nextTitleDateM = 1;
    nextLastM = nextTitleDateM+1
  }else if(nowTitleDateM == 1){
    nowLastM = 12;
    nextTitleDateM = nowTitleDateM+1
    nextLastM = nextTitleDateM+1
  }else{
    nowLastM = nowTitleDateM-1
    nextTitleDateM = nowTitleDateM+1
    nextLastM = nextTitleDateM+1
  }  
  //天数和存放位置
  update(); 
  //插入到日期数的TD当中     
  insertTd();  
  //更新日期标题
  updateTitle();
 })
 //点击下一个月
