如何在SlickJS滑块中设置默认活动元素

Question

我有滑动滑块女巫显示按日期排序的元素，我想预先选择最后一个（当前月份）为默认元素。 例如，如果我有

[01 2015年02 2015年03 2015年04 2015年05 2015年06 2015年]

我想显示06 2015年，当你刷卡向后变老坐骑。

基本上你在这里要做的是将初始幻灯片设置为当前月份。解决方案或多或少直截了当。例如可执行的正下方：

$('.myslider').slick({ 
 
    initialSlide: ((new Date).getMonth()) 
 
});

/* Slider */ 
 
.slick-slider 
 
{ 
 
    position: relative; 
 

 
    display: block; 
 

 
    -moz-box-sizing: border-box; 
 
     box-sizing: border-box; 
 

 
    -webkit-user-select: none; 
 
     -moz-user-select: none; 
 
     -ms-user-select: none; 
 
      user-select: none; 
 

 
    -webkit-touch-callout: none; 
 
    -khtml-user-select: none; 
 
    -ms-touch-action: pan-y; 
 
     touch-action: pan-y; 
 
    -webkit-tap-highlight-color: transparent; 
 
} 
 

 
.slick-list 
 
{ 
 
    position: relative; 
 

 
    display: block; 
 
    overflow: hidden; 
 

 
    margin: 0; 
 
    padding: 0; 
 
} 
 
.slick-list:focus 
 
{ 
 
    outline: none; 
 
} 
 
.slick-list.dragging 
 
{ 
 
    cursor: pointer; 
 
    cursor: hand; 
 
} 
 

 
.slick-slider .slick-track, 
 
.slick-slider .slick-list 
 
{ 
 
    -webkit-transform: translate3d(0, 0, 0); 
 
     -moz-transform: translate3d(0, 0, 0); 
 
     -ms-transform: translate3d(0, 0, 0); 
 
     -o-transform: translate3d(0, 0, 0); 
 
      transform: translate3d(0, 0, 0); 
 
} 
 

 
.slick-track
