idangerous swiper issue with dynamic content

问题

I am applying the idangerous swiper scrollbar plugin on a container whose content is dynamically loaded with ajax, I initialize the plugin after the ajax call, the issue is that the scroll doesn't work until I resize the browser. I have tested it with static content it's working fine, no need to resize the window but once I switch to dynamic content, the scroll won't work unit I resize the browser.

Here's how am initializing the plugin

var mySwiper = new Swiper('.swiper-container', {
        scrollContainer: true,
        mousewheelControl: true,
        mode: 'vertical',            
        scrollbar: {
            container: '.swiper-scrollbar',
            hide: true,
            draggable: false
        }
    });  

here's the html

<div class="swiper-container">
    <div class="swiper-wrapper">
        <div class="swiper-slide">
            <div class="searchList">
                //here's the dynamic content being loaded (a list of div elements)
            </div>
        </div>
    </div>
    <div class="swiper-scrollbar">
    </div>
</div>

swiper-container height is 100%

I found the solution, I added this function which I call after first initializing the plugin

function reinitSwiper(swiper) {
  setTimeout(function () {
   swiper.reInit();
  }, 500);
}

This fix was mentioned in another plugin and when I tried it with this swiper plugin it worked. It has something to do with the plugin not aware of the change that occurred to the DOM.

I've got a no-JS solution.

HTML

<div class="responsive-swiper-holder">

  <div class="responsive-swiper-shiv"></div>

  <div class="swiper-container">
      <div class="swiper-wrapper">
          <div class="swiper-slide">Slide 1</div>
          <div class="swiper-slide">Slide 2</div>
          <div class="swiper-slide">Slide 3</div>
      </div>
  </div><!-- .swiper-container -->

</div><!-- .responsive-swiper-holder -->

CSS

.responsive-swiper-holder {
  position: relative;
}

.responsive-swiper-shiv {
  padding-top: 31.25%;
}

.swiper-container {
  position: absolute;
  height: 100%;
  width: 100%;
  top: 0;
}

.swiper-wrapper, .swiper-slide {
  height: 100%;
}

Consequently this method will also work for making any div size responsively the way an image would. Scaling it's height with a locked aspect ratio of it's width.

The magic is that browsers treat margin/padding % values as a percentage of the width of the element even if you are padding the top or bottom of said element.

Hope this helps!

My fix for Swiper 3.x (I believe the above covers 2.x)

function fixSwiperForIE(swiper) {
    setTimeout(function () {
        swiper.onResize();
    });
}

回答4:

Updated for Change in Swiper documentation since .reInit is no longer a function.

function reinitSwiper(swiper) {
  setTimeout(function () {
   swiper.update();
  }, 500);
}

I just wanted to add that I also had trouble getting Swiper to work with dynamically loaded content through ajax. This is quite obviously because the content wasn't loaded yet when Swiper was intiated. I solved this by using swiper's own appending function instead of my own. This was on version 3.3.1, and it fixed it for me without needing to use setTimeout() or anything!

//quick and dirty creation of html to append
var imgHTML = "";
  $.each(imgArray, function (i, url) {
    imgHTML += '<div class="swiper-slide"><img src="' + url + '" alt=""/></div>';
  });

  //initiate swiper
  var mySwiper = new Swiper('.swiper-container', {
    // Optional parameters
    loop: true,
    autoHeight: true
  });

  mySwiper.appendSlide(imgHTML); //append the images
  mySwiper.update(); //update swiper so it redoes the bindings
  });

I hope this helps some people in need!
