<div id="skills" class="sectionWrapperInner">
  <div>Slide 1</div>
  <div>Slide 2</div>
  <div>Slide 3</div>
</div>

I get error TypeError: b.$slides is null when i am trying to resize the window.

下面是我正在使用的jQuery Slick的代码

$(document).ready(function(){
     function slickIt(){
          if(!$('.sectionWrapperInner').hasClass('slick-initalized')){
              setTimeout(function(){
                  $('.sectionWrapperInner').slick({
                       responsive: [
                            {
                            breakpoint: 9999,settings: "unslick"
                            },{
                            breakpoint: 1199,settings: {
                                mobileFirst: true,slidesToShow: 4,slidesToScroll: 4,dots: true,focusOnSelect: true,infinte: true,}
                        },{
                            breakpoint: 640,slidesToShow: 2,slidesToScroll: 2,]
                  });
              },100)
          }
     }
     $(window).bind('resize',function(){
          slickIt();
     });
     slickIt();
});

任何想法,为什么我总是在调整屏幕大小.
