将随机平铺图像加载到样式/背景中

Question

I currenly utilize this function to randomly fetch an image我目前使用这个 function 来随机获取图像

<script>
window.onload = choosePic;
var myPix = new Array(
"https://ry3yr.github.io/OSTR/Diarykeepers_Homepage/extrafiles/images/bgfiles/cool_stuff_anim.gif",
"https://ptgmedia.pearsoncmg.com/images/chap4_9780321996701/elementLinks/04fig15.jpg");
function choosePic() {
     var randomNum = Math.floor(Math.random() * myPix.length);
     document.getElementById("myPicture").src = myPix[randomNum];}
</script>

<style> body {background-image: url(myPicture);}</style>

<!--<img src="https://pt" width="305" height="312" id="myPicture">-->

However it won't load into the bg as part of the css.但是它不会作为 css 的一部分加载到 bg 中。
