定义颜色的唯一好的样式是CSS.因此，在JavaScript中执行此操作的唯一好方法是更改​​或添加元素的样式.最方便的方法之一是使用jQuery:
http://en.wikipedia.org/wiki/JQuery [ http://jquery.com/ [ ^ ].

您可以使用jQuery .addClass，.removeClass或.toggleClass方法:

The only good style of defining colors is CSS. Therefore, the only good way to do this in JavaScript is changing or adding the style of the element. And one of the most convenient way of doing this is using jQuery:
http://en.wikipedia.org/wiki/JQuery[^],
http://jquery.com/[^].

You can use the jQuery .addClass, .removeClass or .toggleClass methods:

myElement =

(" )； // 在HTML中用id ="myElement"标记元素的元素 className = " ; myElement.addClass(className); // 变红 myElement.removeClass(className); // 恢复以前的类，从而恢复CSS属性 // 或 myElement.toggleClass(className); // 切换它

("#myElement"); //find element where the element is marked with id="myElement" in HTML className = "yellowBackground"; myElement.addClass(className); //make red myElement.removeClass(className); //restore previous classes and hence CSS properies //or myElement.toggleClass(className); //toggle it

自然，您将需要CSS中的对应类:

Naturally, you would need the correspondent classes in CSS:

.yellowBackground { background-color: yellow; }
