在網(wǎng)站開發(fā)過程中，我們用得很多的插件之一就是swiper,但是我們在做左右多個slider切換的時(shí)候，當(dāng)換到手機(jī)端上的時(shí)候，我們需要切換顯示的個數(shù)。如果下圖：

比如PC端一行顯示4個圖片：

JS:

 var swiper = new Swiper('.swiper-container', {
              slidesPerView: 4,
              spaceBetween: 30,
              loop: true,
               autoplay:true,
                speed: 500,
                // 如果需要分頁器
            pagination: {
              el: '.swiper-pagination',
              clickable :true,
            },
            
            // 如果需要前進(jìn)后退按鈕
            navigation: {
              nextEl: '.swiper-button-next',
              prevEl: '.swiper-button-prev',
            },
            });

但是顯示在手機(jī)上不能顯示4個，需要顯示1個或者兩個。

    var swiper = new Swiper('.swiper-container', {
                slidesPerView: 1,
                spaceBetween: 30,
                loop: true,
                 autoplay:true,
                  speed: 500,
                  // 如果需要分頁器
              pagination: {
                el: '.swiper-pagination',
                clickable :true,
              },
              
              // 如果需要前進(jìn)后退按鈕
              navigation: {
                nextEl: '.swiper-button-next',
                prevEl: '.swiper-button-prev',
              },
              });

那么我們就可以通過JS來監(jiān)聽窗口的大小變化來調(diào)用不同的代碼。

代碼如下：

 //打開網(wǎng)頁時(shí)的寬度，必須保留
var windowsize = $(window).width();
  if( windowsize > 768 ) {             //  屏寬1330觸發(fā)
              //主體
           var swiper = new Swiper('.swiper-container', {
              slidesPerView: 4,
              spaceBetween: 30,
              loop: true,
               autoplay:true,
                speed: 500,
                // 如果需要分頁器
            pagination: {
              el: '.swiper-pagination',
              clickable :true,
            },
            
            // 如果需要前進(jìn)后退按鈕
            navigation: {
              nextEl: '.swiper-button-next',
              prevEl: '.swiper-button-prev',
            },
            });
           //主體
           
      }else{
           
            //主體        
          var swiper = new Swiper('.swiper-container', {
                slidesPerView: 1,
                spaceBetween: 30,
                loop: true,
                 autoplay:true,
                  speed: 500,
                  // 如果需要分頁器
              pagination: {
                el: '.swiper-pagination',
                clickable :true,
              },
              
              // 如果需要前進(jìn)后退按鈕
              navigation: {
                nextEl: '.swiper-button-next',
                prevEl: '.swiper-button-prev',
              },
              });
            //主體

      }



  //監(jiān)測網(wǎng)頁時(shí)的寬度變化，以及實(shí)時(shí)更新     
$(window).resize(function() {
  windowsize = $(window).width();
      if( windowsize > 768 ) {             //  屏寬1330觸發(fā)
              //主體
           var swiper = new Swiper('.swiper-container', {
              slidesPerView: 4,
              spaceBetween: 30,
              loop: true,
               autoplay:true,
                speed: 500,
                // 如果需要分頁器
            pagination: {
              el: '.swiper-pagination',
              clickable :true,
            },
            
            // 如果需要前進(jìn)后退按鈕
            navigation: {
              nextEl: '.swiper-button-next',
              prevEl: '.swiper-button-prev',
            },
            });
           //主體
           
      }else{
           
            //主體        
          var swiper = new Swiper('.swiper-container', {
                slidesPerView: 1,
                spaceBetween: 30,
                loop: true,
                 autoplay:true,
                  speed: 500,
                  // 如果需要分頁器
              pagination: {
                el: '.swiper-pagination',
                clickable :true,
              },
              
              // 如果需要前進(jìn)后退按鈕
              navigation: {
                nextEl: '.swiper-button-next',
                prevEl: '.swiper-button-prev',
              },
              });
            //主體

      }
  });

以上是用JS來寫的。現(xiàn)在提供另一方法 就是swiper自帶的效果：

 var swiper = new Swiper('.swiper-container', {
              slidesPerView: 4,
              spaceBetween: 30,
              loop: true,
               autoplay:true,
                speed: 500,

                // 如果需要分頁器
            pagination: {
              el: '.swiper-pagination',
              clickable :true,
            },
            
            // 如果需要前進(jìn)后退按鈕
            navigation: {
              nextEl: '.swiper-button-next',
              prevEl: '.swiper-button-prev',
            },
            
            //響應(yīng)式個數(shù)          
            breakpoints: {               
            //當(dāng)寬度小于等于640時(shí)顯示
              640: { 
                slidesPerView: 1,
                spaceBetween: 20
               },
            //當(dāng)寬度小于等于768時(shí)顯示
              768: {
                slidesPerView: 3,
                spaceBetween: 30
               },
            //當(dāng)寬度小于等于992時(shí)顯示
              992: {
                slidesPerView: 4,
                spaceBetween: 30
               }   
            }  

            });
