如何修复背景，以便在此特定代码中不会滚动？
我已经尝试过body.setAttribute（＆＃34; backgroundAttachment＆＃34;，＆＃34; fixed＆＃34;）;但是它没有用。

<!-- Activate cloaking device
var randnum = Math.random();
var inum = 5;
// Change this number to the number of images you are using.
var rand1 = Math.round(randnum * (inum-1)) + 1;
images = new Array
images[1] = "bf1.jpg"
images[2] = "fifa17.jpg"
images[3] = "rocketleague.jpg"
images[4] = "civ6.jpg"
images[5] = "infinitewarfare.png"
// Ensure you have an array item for every image you are using.
var image = images[rand1]
// Deactivate cloaking device -->
</script>
</head>
<body>
<script>
<!-- Activate cloaking device
//document.write('<body background="' + image + '" text="white">');document.body.style.backgroundAttachment = "fixed";
var body=document.querySelector("body");
body.setAttribute("background", image);
body.setAttribute("text", "white");
body.setAttribute("backgroundAttachment", "fixed");
// Deactivate cloaking device -->
</script>
<img src="RANDOM-IMAGE-TO-MAKE-IT-POSSIBLE-TO-SCROLL.png" style="position:absolute; opacity:0.5; TOP:122px; LEFT:140px; width: 1000px; height: 1400px; object-fit: cover;" align="middle">
