单击更改div的背景图像
[英]Change a background image of a div on click
问题描述
Okay, I think my head is being dense. 
好吧，我想我的头很密。 But I cant seem to get this to work. 但我似乎无法使它正常工作。 I'm doing a website for a photographer, and he wants to be able to let a user change the frame that they would like from a choice of 3. Easiest way I thought to do this was to create a div, and then have it change class based on a button click. 我正在为摄影师创建一个网站，他希望能够让用户从3的选择中更改他们想要的框架。我认为最简单的方法是创建一个div，然后使用它通过单击按钮更改类。 So it would change the background image. 因此它将改变背景图像。 However I cant get it to do this. 但是我无法做到这一点。 Any ideas would be well received, as I'm guessing theres probably a javascript version that does it quicker and easier. 任何想法都会受到欢迎，因为我猜可能会有一个javascript版本，它可以更快，更轻松地完成它。

className不是DOM元素中style对象的一部分，而是直接属性：
document.getElementById("pictureframe").className = 'wooden';

If you want to use some other class for style, than you probably need to go with something like this: 如果您想使用其他类作为样式，则可能需要执行以下操作：
function replaceClass(className) {
$('#pictureframe').removeClass('plain black wooden');
return $('#pictureframe').addClass(className);
}
This way you can keep class with styles http://jsfiddle.net/NjTea/5/ 这样，您可以使用样式http://jsfiddle.net/NjTea/5/
