<图片及GT; src（活动源） [英] <picture> src (active source)

问题描述

有没有办法在不使用视口宽度/像素密度的情况下在javascript中检索< picture> 元素当前使用的源？

Is there a way to retrieve a <picture> element's currently used source in javascript without using the viewport width / pixel density?

与类似的内容< select>：已选择

任何人都可以这个？

推荐答案

< picture> 元素仍然是实验性的，所以我认为还没有API来获取活跃源。但是，我确实为< picture> 规范找到了以下问题，期望该元素具有 currentSrc 元素。

The <picture> element is still experimental so I do not think there is an API to get the "active" source yet. I did however find the following issues for the <picture> spec expecting the element to have a currentSrc element.

currentSrc 是我也会有的行为预计但目前它还没有在Chrome或FireFox中实现。

currentSrc is the behaviour I also would have expected but currently it is simply not implemented in Chrome or FireFox.
