随机体背景图像 [英] Random body background-image

问题描述

我在网上尝试了几个教程，但似乎没有一个可以正常工作.我想我想做的很简单:

I've tried several tutorial on the web and none seems to work properly. What I'm trying to do is quite simple I think:

我需要在页面加载时随机显示 9 张不同的 .jpg 图像 - 作为背景.这应该很简单吧?

I have 9 different .jpg images that I need to randomly show up on page load - to be background. This should be fairly simple right?

谢谢，

编辑(抱歉，忘记附上代码 - 在网络上找到):

EDIT (Sorry, forgot to attach the code - found in the web):

$(document).ready(function(){

    bgImageTotal=9;

    randomNumber = Math.round(Math.random()*(bgImageTotal-1))+1;

    imgPath=('../img/bg/'+randomNumber+'.jpg');

    $('body').css('background-image', ('url("'+imgPath+'")'));

});

推荐答案

查看本教程:http://briancray.com/2009/12/28/simple-image-randomizer-jquery/

首先创建一个图像数组:

First create an array of images:

var images = ['image1.jpg', 'image2.jpg', 'image3.jpg', 'image4.jpg', 'image5.jpg'];

然后，设置一张随机图片作为背景图片:

Then, set a random image as the background image:

$('body').css({'background-image': 'url(images/' + images[Math.floor(Math.random() *      images.length)] + ')'});

应该没问题.
