Jssor - 如何保持图像宽高比？

Question

有时照片长宽比与幻灯片容器不同,我看到照片将被拉伸以填充所有容器空间.

是否有任何选项可以避免这种情况,使照片长宽比不变？肯定会有一些空白,但照片中的形状不会改变.

Answer 1

请设置$ FillMode选项,0:streach,1:包含,2:cover,4:实际大小,5:包含大图像和小图像的实际大小.

值1或2或4将是保持纵横比的不错选择

<script>

    jQuery(document).ready(function ($) {
        var options = {
            $FillMode: 1,                                      //[Optional] The way to fill image in slide, 0 stretch, 1 contain (keep aspect ratio and put all inside slide), 2 cover (keep aspect ratio and cover whole slide), 4 actuall size, 5 contain for large image and actual size for small image, default value is 0
            $AutoPlay: true,                                   //[Optional] Whether to auto play, to enable slideshow, this option must be set to true, default value is false
            $DragOrientation: 3                                //[Optional] Orientation to drag slide, 0 no drag, 1 horizental, 2 vertical, 3 either, default value is 1 (Note that the $DragOrientation should be the same as $PlayOrientation when $DisplayPieces is greater than 1, or parking position is not 0)
        };

        var jssor_slider1 = new $JssorSlider$("slider1_container", options);
    });
</script>
