HTML SVG实现的Loading条

阅读(1976)

SVG支持 IE9及以上,可以内嵌到HTML中直接完成loading的动画加载效果。

好处在于:

  1. 无须依赖外部文件
  2. 矢量的,随意换大小
  3. 随意换颜色
<div class="P-loadingUI">
    <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="40px" height="40px" viewBox="0 0 50 50" style="enable-background:new 0 0 50 50;" xml:space="preserve">

        <animateTransform attributeType="xml"
          attributeName="transform"
          type="rotate"
          from="0 20 20"
          to="360 20 20"
          dur="0.5s"
          repeatCount="indefinite"/>
        </path>
    </svg>
</div>

效果如下:
