javascript - 浏览器调整大小中的宽度问题

Question

我有li元素，我使用javascriptposition:absolute定位它们。transform:translate()当浏览器窗口调整大小时，我需要重新定位它们，它工作正常，但是当媒体查询之间和之间的li宽度发生变化时，元素在某些屏幕尺寸下无法正确定位，这是因为元素的实际与它不同中计算。50%25%widthjavascript

HTML：

<div class="galleryList">
  <ul>
    <li class="filter-gallery">
      <a href="#">
        <img src="pics/g1.jpg" alt="">
      </a>
      </li>
      <li class="filter-gallery">
        <a href="#">
        <img src="pics/g2.jpg" alt="">
        </a>
      </li>
      <li class="filter-gallery">
        <a href="#">
          <img src="pics/g3.jpg" alt="">
        </a>
      </li>
      <li class="filter-gallery">
        <a href="#">
          <img src="pics/g4.jpg" alt="">
        </a>
      </li>
      <li class="filter-gallery">
        <a href="#">
          <img src="pics/g5.jpg" alt="">
        </a>
      </li>
      <li class="filter-gallery">
      <a href="#">
        <img src="pics/g6.jpg" alt="">
      </a>
      </li>
      <li class="filter-gallery">
      <a href="#">
        <img src="pics/g7.jpg" alt="">
      </a>
      </li>
      <li class="filter-gallery">
        <a href="#">
          <img src="pics/g8.jpg" alt="">
        </a>
        </li>
      </ul>
    </div>

CSS：

    img{
       max-width:100%;
    }
    .galleryList ul{
      position: relative;
    }
    .filter-gallery{
      width: 50%;
      position: absolute;
      top:0;
      left: 0;
      overflow: hidden;
    }
    @media screen and (min-width: 620px) {
      .filter-gallery{
        width: 25%;
      }
    }

jQuery :

    $(document).ready(function(){

      var filterItems = $(".filter-gallery") ,
      galleryList = $(".galleryList") ;

      positionItems(filterItems);

      function positionItems(filterItems){

        var totalFilterItemswidth = 0 , rows = 0 , newI = 0 , useNewI= false ,
        filterItemsHeight = filterItems.outerHeight() ,
        filterItemsWidth = filterItems.outerWidth() ,
        galleryListWidth = galleryList.outerWidth();

        console.log(filterItemsWidth , filterItems[0]); 

        //positioning filter items
        for(var i=0 ; i < filterItems.length ; i++){
          var currentElement = $(filterItems[i]) ,
          elementIndex = i ,
          x ,
          y = 0;

          if(totalFilterItemswidth == galleryListWidth){ // 1 row completed
            rows++;
            totalFilterItemswidth = 0; //start adding widths again for next rows
            newI = 0;
            useNewI = true;
          }

          if(useNewI){
            elementIndex = newI++;
          }

          y = filterItemsHeight * rows;
          x = elementIndex * filterItemsWidth ,

          currentElement.css({
            transform: "translate(" + x + "px ," + y +"px )" 
          });

          filterItemsWidth = filterItems.outerWidth();

          totalFilterItemswidth += filterItemsWidth;
        }

        galleryList.css({
          height : filterItemsHeight * (rows+1) + "px"
        });

        }

        $(window).resize(function(){
          positionItems(filterItems);
        });
    });

console.log()在某些屏幕尺寸中显示的宽度与实际宽度不同627px，当我再次调整窗口大小时，它工作正常。

我无法弄清楚为什么会发生这种情况以及如何解决它。

谢谢
