Examples are as follows:
<script>
var imgs =["/cnblogs_com/xiaobo-Linux/1112236/o_2.jpg",
"/cnblogs_com/xiaobo-Linux/1112236/o_default.png",
"/cnblogs_com/xiaobo-Linux/1112236/o_3.jpg",
"/cnblogs_com/xiaobo-Linux/1112236/o_1.jpg",
"/cnblogs_com/xiaobo-Linux/1112236/o_4.jpg",
"/cnblogs_com/xiaobo-Linux/1112236/o_5.jpg",
"/cnblogs_com/xiaobo-Linux/1112236/o_6.jpg",
"/cnblogs_com/xiaobo-Linux/1112236/o_default",
];
var index=(()*8);
var img = imgs[index];
function time(){
="url("+img+")";
}
= function(){
time();
}
</script>
The above simple example of randomly switching background images in js settings is all the content I share with you. I hope you can give you a reference and I hope you can support me more.
